IBM subsequent week will debut its subsequent generation X-architecture to enhance the fortunes of its Intel-primarily based servers in the cloud computing and big records markets, in line with sources generic with the company’s plans.
The X6 architecture, which additional evolves the X5 architecture’s conception of disaggregating processors from reminiscence in large racks of servers, is a complete remodel of a standard server rack with tremendously elevated density and server performance. X6 is built around a “mid-plane structure” that also borrows from Intel Corp.’s QuickPath Internconnect (QPI) know-how to permit quick reminiscence-to-reminiscence transfer quotes, sources noted.
The renewed emphasis on Intel servers follows speculation final 12 months that IBM became searching its Intel-based xSeries of servers around, largely as a result of earnings on the road have been falling and the know-how was fitting too commoditized for IBM’s liking.
The upcoming X6 employs the conception of “books,” or modules, which contain an Intel processor and/or twin in-line memory modules (DIMMs). There should be a Compute ebook with a CPU and up to 24 DIMMs and a Storage publication that can also be stuffed with up to 6.four terabytes of xFlash storage with as much as 12.eight terabytes of Serial attached SCSI (SAS), in keeping with sources.
“This isn’t trivial stuff to tug off. This (structure) makes it possible for storage-to-memory and reminiscence-to-reminiscence to work at in regards to the identical velocity. be sure to easily be able to do just about any compute or reminiscence intensive project completely in reminiscence,” based on an East-coast-based mostly consultant generic with IBM's X6 strategy, who requested anonymity.
probably the most talents benefits of the brand new structure is enabling company clients, specifically those within the financial services and pharmaceutical industries, to make more valuable use of analytics and large databases on the departmental degree in terms of productiveness and cost savings.
“probably the most complaints individuals have about all these I/O hungry purposes is the way to push analytics and large databases down so departments can work with them. however with (IBM’s) use of flash reminiscence, it feels like they can try this, and retailer (clients) a bunch of money,” the advisor referred to.
“you could now take your present storage and put that in the background like a 2nd tier of storage since you aren’t working with spindles or rotating drives anymore,” noted one IBM insider who requested anonymity.
IBM next week will claim that the new architectural advancements should still result, on normal, in reductions of 43% with three times lessen latency for a lot of IT stores, sources stated.
“that you could without delay entry 3 times the amount of reminiscence through this reminiscence channel storage, which is in fact flash reminiscence,” in keeping with the East coast IT consultant. “so that you will get very low latency on account of the way they have got built-in caching technology with the memory bus.”
Some observers believe the brand new X6 structure might supply the series a hipper technology photo, thereby attracting greater hobby amongst expertise consumers.
“The xSeries is still a plausible enterprise however it does need a shot in the arm for certain. I believe they see this announcement as doing just that,” stated one industry observer who requested anonymity.X6 elements consist of higher resiliency
the brand new architecture additionally introduces a stronger diploma of resiliency, including an greater capacity to intelligently identify and work round failures and admins to take preventative steps to relevant them. IT specialists can carry out a number of distinctive system management tasks the usage of digital equipment, which should aid hold IT support costs down, based on sources.
QPI is an architecture first put into chips by means of Intel in 2008. It has additionally been used in IBM xSeries servers before. It allows for memory-to-reminiscence connections between chips inside a server to boost performance. within the case of X6, this technology is also being used to join disks, both Flash and Serial attached SCSI (SAS), to the CPU at the velocity of memory.
QuickPath Interconnect additionally permits CPUs to entry reminiscence in a system other than that which is without delay connected to the chip, the use of what’s referred to as some extent-to-aspect connection. element-to-aspect connections are unbiased from one an extra and do not require a shared communications bus, which can turn into a bottleneck.
Now with X6, large amounts of direct-connected Flash and spinning disk storage can be packed into an xSeries box, with reminiscence-quick efficiency. Direct-attached storage (DAS), once considered an ancient-school means of storing statistics, has seen a revival in contemporary years for every little thing from high-performance databases utilized in facts analytics to scale-out architectures used via cloud computing carrier providers.
greater, excessive-reminiscence servers can even be universal in virtualization retail outlets as a result of virtual machines that share a bigger pool of supplies come across less rivalry, in response to Bob Plankers, virtualization and cloud architect at a massive Midwestern institution.
Plankers' store runs mainly Dell hardware, and while the X6 seems fascinating, he stated, it doubtless gained’t be ample to immediate a swap in providers.
“You even have pitfalls to bigger servers – it capability you have loads of eggs in one basket, too,” Plankers mentioned.
another IT professional said he preferred what he heard of the new alterations to the architecture, which may help the efficiency of 1 critical utility in his ambiance it is certainly disk I/O intensive. despite the fact, an aggressive movement to flash storage may show too expensive right now.
“At this point there continues to be too much of a financial premium to go to flash, so they wouldn’t be making the movement with anything like this now," spoke of Nigel Fortlage CIO, Social enterprise chief with GHY international, in Winnipeg Canada."but with engineering changes similar to these, i would agree with entertaining a know-how like this within the next few years.”
newsIBM Opens home windows .web, Xeon MP excessive-end Benchmarking with a Roar
The benchmark, published ultimate week, was the primary check showing the performance of Intel's new Xeon MP chips on a device with more than four processors.
IBM used eight 1.6-GHz Xeon MPs on one in all its eServer xSeries 440s. The x440 is IBM's modular new server that contains four-processor bricks that can also be combined to create SMP servers of as much as 16 processors. When the sixteen-processor capability ships, IBM can be the primary important OEM to offer an Intel-based server domestically of greater than eight processors apart from Unisys, which has bought 32-processor servers for a few years.
premiere Intel-primarily based 8-manner
IBM's influence on the TPC-C confirmed greater than a 30 % uncooked efficiency growth over the old optimal eight-processor outcomes -- Dell PowerEdge and HP ProLiant methods each operating windows 2000 Datacenter and 900-MHz Intel Pentium III Xeons. The IBM device hit ninety two,398 transactions per minute on the TPC-C benchmark (tpmC). Dell's mark, set final August, was 69,901 tpmC. HP's effect, posted in February, become 69,169 tpmC.
robust against 8-means Unix techniques
The x440 also held its personal against eight-processor midrange RISC systems from IBM and Bull, both operating IBM's AIX working device. The eServer x440 reached 92,398 transactions per minute on the TPC-C benchmark (tpmC), which is third at the back of the one hundred and five,025 tpmC result carried out with each IBM's eServer pSeries 660 and the Bull Escala PL800R. The Unix benchmarks have been published closing September.
top of the line 8-manner in expense/efficiency
The IBM xSeries pulled far from the container on expense/efficiency, although. Its $7.70/tpmC was less than Dell ($eight.forty six), HP($9.forty three), the IBM pSeries ($23.45) and Bull ($25.forty one).
developing an IBM-Unisys Smackdown
The benchmark additionally offers IBM a robust scalability story versus the 800-pound gorilla in home windows-based scalability -- the 32-processor Unisys ES7000 -- for now. Unisys has the most excellent home windows-primarily based SMP influence on the TPC benchmark so far with its November posting of as a result a hundred sixty five,219 tpmC.
For awhile, IBM can play up the incontrovertible fact that its eight-manner can present more suitable than half that efficiency at a bit over one-third the fee/transaction. extra sweetening the IBM story is the headroom obtainable when it ships 16-manner programs.
besides the fact that children, Unisys has already unveiled its next era of CMP servers, and subsequent month is determined to beginning shipping two models tuned for the Xeon MP processor, including one mannequin with a extra aggressive fee that may still put it in tighter competition with IBM on that entrance.
IBM's proprietary method with the "Summit" chipset that undergirds its x440 servers gives it a head beginning within the eight-method, Intel-based area. No business-typical eight-processor chipset is presently transport for the Xeon MP for rival organizations like HP or Dell to plug into server designs.
The choice of the beta code of home windows .internet Datacenter Server does put IBM's benchmark influence at risk.
The server techniques in the back of benchmarks submitted to the TPC must be purchasable within six months. IBM put a Jan. 21, 2003 availability date on its outcomes. Microsoft has only promised to RTM home windows .net Server by the conclusion of the year. Any delay may cause IBM to should withdraw the outcome.
Scott Bekker is editor in chief of Redmond Channel associate journal.
Three years and one hundred-million greenbacks later, IBM has introduced its eServer X3 architecture servicing Intel Xeon processor-based mostly servers with guide for Intel's newest dual core sixty four-bit processor.
X3, with its "hurricane" chip, is the third generation of massive Blue's commercial enterprise X-architecture and increases 4-manner performance by way of 38 % over the previous era. The ensuing xSeries servers are designed to support sixty four-bit and 32-bit functions simultaneously, letting businesses progressively migrate to sixty four-bit on a necessity best foundation.
determining to be slightly less popular in its design, IBM turned to its mainframe prowess. hurricane -- greater specially well-known as the XA-64e chipset -- reduces memory latency, improves response time and typical device efficiency with an integrated processor and reminiscence controller.
IBM's virtual XceL4v Dynamic Server Cache has produces latency so low that L4 cache became now not blanketed in the design.
different technical facets of the chipset include: Embedded DRAM with an built-in snoop filter and remote listing; energetic PCI-X 2.0 as much as 266 MHz; DDR2-primarily based memory support and three scalability ports related to the I/O hub, every maxing out at 6.four GB/s.
IBM additionally dropped in its Virtualization Engine expertise to optimize server consolidation and supply superior commercial enterprise utility efficiency. The business's claims of a 38 % raise in performance were benchmarked the usage of 64GB of memory and recorded the use of the TPC-C performance scale.
"the new xSeries product family in response to X3 attracts from their mainframe abilities and gives unheard of benefits for customers looking for the most subtle capabilities and performance from their application purposes," talked about Susan Whitney, established manager for eServer xSeries, IBM techniques and expertise community.
a large scale roll out of the IBM eServer xSeries 366 server will happen inside the next 90 days, synchronized with the release of new sixty four-bit working methods from Microsoft, red Hat and Novell. Pricing for the x366 starts off at $6,999 USD and is subject to the phrases of IBM's pay–as-you-go server family "investment insurance plan" mannequin.

Windows Server 2008 R2 provides several new benefits that help organizations better administer their networking environment. These new features provide better file and data management, better performance monitoring and reliability tracking tools to identify system problems and proactively address issues, a new image deployment tool, and a whole new set of Group Policy Objects that help administrators better manage users, computers, and other Active Directory objects.Improvements in the Group Policy Management
Windows Server 2008 R2 introduces over 1,000 new Group Policy Objects specific to Windows Server 2008 R2 and Windows 7, along with several new components that expand on the core capabilities of Group Policy management that have been part of Windows 2000/2003 Active Directory. The basic functions of Group Policy haven't changed, so the Group Policy Object Editor (gpedit) and the Group Policy Management Console (GPMC) are the same, but with more options and settings available.
As mentioned earlier, the Group Policy Management Console can either be run as a separate MMC tool, or it can be launched off the Features branch of the Server Manager console tree, as shown in Figure 1.7. Group policies in Windows Server 2008 R2 provide more granular management of local machines, specifically having policies that push down to a client that are different for administrator and non-administrator users.
Additionally, applications can now query or register with a network location awareness service within Group Policy management, which provides the identity where a user or computer object resides. As an example, a policy can be written that allows users to have access to applications and files if they are on a local network segment, but blocks users from accessing the same content when they are on a remote segment for security and privacy reasons. This addition to group policies adds a third dimension to policies so that now administrators can not only define who and what someone has access to, but also limit their access based on where they are.
Group policies are covered in detail in Chapter 27, "Group Policy Management for Network Clients," as well as in Chapter 19, "Windows Server 2008 R2 Group Policies and Policy Management."Introducing Performance and Reliability Monitoring Tools
Windows Server 2008 R2 introduces new and revised performance and reliability monitoring tools intended to help network administrators better understand the health and operations of Windows Server 2008 R2 systems. Just like with the Group Policy Management Console, the new Reliability and Performance Monitor shows up as a feature in the Server Manager console. By clicking on the Performance Diagnostic Console, the tool shows up in the right pane, as shown in Figure 1.8.
Figure 1.8 Windows Reliability and Performance Monitor.
The new tool keeps track of system activity and resource usage and displays key counters and system status on screen. The Reliability Monitor diagnoses potential causes of server instability by noting the last time a server was rebooted, what patches or updates were applied, and chronologically when services have failed on the system so that system faults can potentially be traced back to specific system updates or changes that occurred prior to the problem.
By combining what used to be three to four tools into a single console, administrators are able to look at system performance, operational tasks, and historical event information in their analysis of a server problem or system operations instability. You can find more details on performance and reliability monitoring in Chapter 34.Leveraging File Server Resource Manager
File Server Resource Manager (FSRM) was a feature pack add-in to Windows 2003 R2 and has been significantly improved with the release of Windows Server 2008 R2. FSRM is a quota management system of files on network shares across an enterprise. Rather than allowing employees to copy the entire content of their laptop to a network, or potentially back up their MP3 audio files onto a network, FSRM provides the ability to not only limit the amount of content stored on network shares, but also to set quotas (or limit storage altogether) on certain file types. So, a user could be limited to store 200GB of files on a network share, but of that limit, only 2GB can be allocated to MP3 files.
FSRM, shown in Figure 1.9, in Windows Server 2008 R2 has been improved to allow the nesting of quotas to ensure the most restrictive policy is applied. Quotas can also transcend subfolders, so as new folders are created, or as policies are applied at different levels in a folder hierarchy, the policies still apply, and the rules are combined to provide varying levels of quota allocation to user data. Additionally, quotas are now based on actual storage, so if a file is compressed when stored, the user will be able to store more files within their allocated quota.
File Server Resource Manager is covered in detail in Chapter 28.Leveraging the Best Practice Analyzer
Included in Windows Server 2008 R2 is a built-in Best Practice Analyzer. Found in the Server Manager console tool, the Best Practice Analyzer runs a series of tests against Active Directory roles, such as the Hyper-V role, the DNS role, and the Remote Desktop Services role, to assess whether the role has been installed and configured properly and to compare the installation with tested best practices.
Some of the results from the Best Practice Analyzer could tell an administrator they need to add more memory to a server, to move a role to a separate server to improve role optimization, or to shift a database to a different drive on the server to distribute disk performance demands on the system. More details on the Best Practice Analyzer are covered in Chapter 20.Introduction of Windows Deployment Services
Windows Server 2008 introduced a new tool called Windows Deployment Services (WDS), which was effectively an updated version of the Remote Installation Services (RIS) that has been available for the past several years. Unlike RIS, which was focused on primarily scripted installations and client images, WDS in Windows Server 2008 R2 can distribute images of Windows 7 clients or Windows Server 2008 R2 servers in a significantly more flexible and modifiable deployment process.
Like with RIS, Windows Deployment Services allows a client system to initiate a Preboot Execution Environment (PXE), effectively "booting" to the WDS server to see a list of images that can be deployed on the system. Alternately, an organization can create a Windows PE boot disc and have an image initiated from a CD or DVD.
With Windows Server 2008 R2 and Windows 7, the image can be created in Windows Imaging (WIM) format, which allows for the injection of patches, updates, or even new code to a WIM file without even booting the image file. This provides the organization with more than just static images that get pushed out like in RIS, but rather a tool that provides ongoing and manageable updates to image files.
WDS also supports the imaging of Windows 2003 servers and Windows XP client systems in the same manner that RIS did in terms of pushing out images or using an unattend script file to send images to systems.
Windows Deployment Services is covered in detail in Chapter 26, "Windows Server 2008 R2 Administration Tools for Desktops."
With the latest version of the Windows OS, Windows 7, LabVIEW users can unlock new technologies.
Instead of adding significantly new or different functionality in Windows, Microsoft improved many of the features introduced in Windows Vista, refined the usability of the shell, and increased the system responsiveness and performance. These changes, combined with a focus on hardware and software compatibility, make Windows 7 a strong candidate for the latest test and measurement applications. This article will explain how applications written within the NI LabVIEW graphical development environment can take advantage of Windows 7 and the latest computing platforms to increase data throughput, improve performance, and take advantage of technologies such as 64-bit, USB data acquisition (DAQ), and PCI Express.1. Increasing Throughput with NI USB DAQ and Windows 7
Commercial vendors are already shipping computers with Windows 7. These computers offer the same benefits in overall performance and multiple cores as well as provide the latest bus technologies, including multiple PCI Express and Hi-Speed USB slots.
Microsoft has invested significantly in USB improvements for Windows 7. These improvements, such as the elimination of unnecessary timers, selective hub suspension, and lower enumeration time for USB flash devices, increase the performance of USB test and measurement devices. In recent benchmark testing, the new NI CompactDAQ chassis obtained a 10 percent increase in overall attainable bandwidth with Windows 7, compared to the same hardware running on Windows XP. The increased hardware performance, combined with the multicore optimization of both the Windows 7 OS and LabVIEW software, resulted in a performance increase of up to 20 percent during high-speed or multifunction I/O measurements.
Figure 1. Due to several improved features, the Windows 7 OS isa reliable program for measurement applications written with LabVIEW software.
Back to Top2. High-Performance Measurements with PXI Express and Multicore
Microsoft has restructured much of Windows 7 to perform more system tasks concurrently in order to benefit from increasingly common multicore processors. A key example is the Microsoft rearchitecture of the graphics device interface (GDI), which was designed to improve responsiveness when multiple applications are running simultaneously. This rearchitecture results in fewer sequential obstacles, which can provide a more responsive user interface and better overall system performance of multithreaded measurement applications.
Multithreaded software assigns independent, asynchronous processes to separate threads, which can be executed in parallel by separate computer cores. Computer processors are no longer getting faster; instead, the processor manufacturers are adding more cores onto a single chip. For LabVIEW programmers, it is common to create multiple computationally intensive tasks in a single application that can run in parallel; this is as simple as drawing two loops on a block diagram. LabVIEW and NI drivers, such as NI-DAQmx, are multithreaded, which helps test engineers easily create high-performance acquisition and analysis applications without manually spawning and managing separate threads. DAQ applications written in LabVIEW and use NI hardware on a multicore computer benefit from the improvements in Windows 7 and are designed to further optimize the use of multicore processors.
Measurements that require high throughput and fast performance are prompting engineers to use new technologies such as multicore processors and PXI Express to meet increasing demands for speed. The new NI X Series DAQ devices natively support PCI Express and PXI Express, which offer dedicated bidirectional bandwidth of up to 250 MB/s. NI also offers many additional PXI Express modular instruments for high-precision, high-frequency measurements. Engineers can use these technologies with Windows 7, which supports the latest buses and improves support for multicore processing to remove restrictions and improve data throughput of their measurement applications.
Figure 2. Benchmarks performed with NI CompactDAQ revealed as much as a 20 percent increase in data throughput on Windows 7.
Back to Top3. Understanding the Difference Between 32-Bit and 64-Bit Versions of Windows 7
Windows 7 is the third Microsoft OS to support 64-bit processors. Although 32-bit versions of Windows continue to be the most popular and offer the most native compatibility with applications, 64-bit hardware and software are available. When upgrading to Windows 7, it is important to be aware of the potential benefits and considerations of 64-bit versus 32-bit in order to select the appropriate platform.
The new 64-bit version of LabVIEW 2009, which is available for download from ni.com, is the first version of LabVIEW to offer native compatibility with 64-bit operating systems (Vista and Windows 7 only). Measurement applications that run natively on 64-bit hardware and software can take advantage of a larger amount of physical memory than 32-bit systems, which is beneficial for applications that are processing large amounts of contiguous data. Access to additional memory can easily increase system performance by eliminating the need to swap processes in and out of page files on hard drives, which are much slower than physical memory and cache. Along with increased physical memory, additional registers on a 64-bit processor can increase execution speed of applications by as much as 20 percent, depending on how the code is written. However, only LabVIEW 2009 core software, the NI Vision Development Module, and most NI drivers offer native support for a 64-bit version of Windows. Non-native support for 32-bit versions of applications is made possible by an emulation later known as Windows on Windows (WoW); however, this does adversely impact execution speed and performance.
Test and measurement applications created to analyze large data sets, which are synonymous with high-channel-count systems and fast sampling rates, may benefit from the switch to a 64-bit version of Windows 7. However, a majority of LabVIEW applications will not inherently benefit from switching to 64-bit versions.
Figure 3. With Windows 7, the performance of a LabVIEW application with four parallel loops on a quad-core machine experienced as much as a 10 percent performance increase compared to Windows XP.
Back to Top4. The Microsoft OS Support Life Cycle
The introduction of Windows 7 is especially relevant given that Microsoft officially discontinued sales of Windows XP in June 2008. Windows XP, which was released more than nine years ago, continues to be the most popular OS on the market. A recent survey of National Instruments customers indicates that more than 80 percent of their test and measurement applications are still running on Windows XP, while less than 10 percent have adopted Windows Vista. Now that Windows 7 is available, customers have the opportunity to upgrade older PC measurement hardware to take advantage of the latest multicore processors and bus technologies including PCI Express, which provides higher throughput and increases overall system performance.
Back to Top5. Ensuring Hardware and Software Compatibility
Microsoft has clearly indicated that Windows Vista device drivers work correctly on Windows 7 and that the company is not introducing any new compatibility requirements to the driver model. This policy is designed to avoid the same incompatibility problems users experienced when Windows Vista first debuted. (Many common devices did not work or would not install.)
In addition to the compatibility mode option, which helps applications “think” they are running in an older version of Windows, Microsoft is turning to new virtualization technologies in the Windows 7 Professional and Ultimate versions to eliminate the risk that software cannot run on Windows 7. With a new Windows 7 mode, known as Windows XP Mode, users can emulate the popular Windows XP OS. This may present LabVIEW programmers with the easiest possible mechanism for running older applications.
Back to Top6. NI Product Compatibility
With early access to Windows 7, National Instruments has already ensured that the majority of NI application software, including LabVIEW 2009, LabVIEW SignalExpress 2009, and DIAdem 11.1 SP1 – as well as the November version of the NI Device Drivers DVD – already supports Windows 7. Additionally, NI is committed to releasing Windows 7 support for NI LabWindows™/CVI, Measurement Studio, and NI TestStand before the end of 2009. Customers interested in transitioning their measurement and automation systems to Windows 7 in order to take advantage of the new productivity and performance benefits can upgrade today.

The Precision 5820 Tower is Dell's second-most powerful desktop workstation—which, judging by the $5,567 test model they received, is akin to saying the Boeing 747-8 is only the second-biggest airliner in the world. (Precision 5820 models start at $1,249.) It's an evolution of the Precision 5810 Tower, which they reviewed to high praise back in 2015. Dell's pricier Precision 7820 looks similar but offers dual processors, whereas the Precision 5820 offers "just" one: In their test unit, a monster 10-core Intel Xeon W-2155, alone a $1,185 option and requiring an upgrade to Windows 10 Pro for Workstations. They mock-configured a competing HP Z4 with a near-identical loadout, and it came up to $7,118. On paper, the Precision 5820 is a better value and a total beast for pro applications that can take advantage of its specialized memory, pro-grade Quadro/Radeon Pro graphics, ISV certifications, and Xeon horsepower.Laser-Focused on Business
Spiffy, curvy designs aren't a top priority for power-tower workstations like the Precision 5820 Tower. The black-and-silver exterior of this unit has a sober, serious look. You'll have trouble getting its massive 16.5-by-6.9-by-20.4-inch (HWD) hulk of a chassis to blend in anywhere outside a black-box convention.
Sturdy metal carry handles on the front and rear help if you have to move this 34-pound beast around. You'll appreciate them; lugging this tower is like moving a suitcase full of ingots. It can stand upright or even sit on its side, the latter courtesy of rubber feet on its right panel. The metal case is strong enough that you can rest a monitor on top. The front panel has a honeycomb pattern for air intake.
Tool-less access to the interior is courtesy of a switch on the left side panel. The internal components are laid out neatly, as is the wiring. The massive Intel "Skylake-W"-based motherboard has the CPU in the center. It's topped by a tall air cooler, and straddled by eight RDIMM slots for specialized error-correcting DDR4-2666 ECC memory.
The RAM configuration in the review unit I'm looking at comprises eight 8GB DIMMs (64GB total). The memory is running in quad-channel mode for serious bandwidth, and this RAM upgrade adds $1,378 to the base model's 8GB setup. For a "mere" $3,327 over their 64GB setup, you can max out the Precision 5820 Tower with a staggering 256GB of RAM. The review unit is powered by a swappable 950-watt power supply in the top of the chassis, allowing for headroom should you care to configure with more than one video card.
The motherboard offers plenty of room for expandability. You get two PCI Express (PCIe) x16 slots in full x16 bandwidth for graphics cards, one PCIe x16 wired internally as an x8 slot, another wired as x4, and one final PCIe x16, wired for x1. There's even a single old-school PCI slot. You can install PCIe cards without screws or tools; a clip holds down a retainer bar that keeps cards in place.
For storage, the motherboard has eight SATA ports, plus one extra that's allocated to an optical drive. If you want an M.2 slot for high-speed SSDs, however, you'll need to opt for one or more of Dell's PCIe Ultra-Speed cards.
The review unit I have in hand has the Dell Ultra-Speed Duo card, which has two M.2 Type-2280 slots on it, one of which is occupied by a 512GB PCIe drive with NVMe support. On their unofficial Crystal DiskMark benchmark testing (using a 50MiB cluster size), the drive delivered 2,188MBps read and 1,363MBps write speeds. Those aren't record-breaking numbers, but that doesn't detract from the fact that it's very fast storage. (A Dell Ultra-Speed Quad card, with four M.2 slots, is also an option.)
Dell offers the Precision 5820 Tower in configurations with up to 24TB of storage. With aftermarket drives, you can go higher than that, even, on the internal storage. The chassis fits up to six 2.5-inch or five 3.5-inch drives, plus the mentioned M.2 SSDs. Given the ready availability of 10TB 3.5-inch hard drives, your only limit is your budget.
Four of the 3.5-inch drive bays are accessible by removing the right-side grillework portion of the front panel. The drives themselves are hot-swappable; just pull the release handle and slide out the caddy. To add another 2.5- or 3.5-inch drive, you'd need to sacrifice the 5.25-inch optical bay, which came occupied in this test unit by an 8x DVD burner in the tester reviewed here. Alternately, you can always go with external drives to expand the storage, especially if you spring for an optional PCIe expansion card with two Thunderbolt 3 ports.Connected to the Nines
Like power and gravitas, ports and slots are something the Precision 5820 Tower has no shortage of.
The front of the test unit here has a full array: a headphone/microphone combination jack, two Type-C USB 3.0 ports (the topmost one supporting PowerShare, for device charging over USB with the system powered down), a pair of Type-A USB 3.0 ports, a full-size SD card slot, and the power button.
On the rear, the ports on the motherboard's panel include six Type-A USB 3.0 ports, onboard Ethernet, PS/2 mouse and keyboard ports, a serial port, and microphone line-in (blue) and audio line-out (green) ports. The rest of the ports back here will vary depending on the configuration you opt for. The tester machine received at PC Labs makes use of an Nvidia Quadro P4000 graphics card, and thus had four DisplayPort video-out connectors. It also has an Intel PCIe network card with a single Ethernet port, plus another PCIe card with two Type-C USB 3.1 ports and a DisplayPort video-in connector.
Dell's $99.99 KM717 keyboard and mouse combo is included in the price of this review unit. Both devices wirelessly connect through a single USB dongle, each powered by a pair of included AAA batteries.
The keyboard has an aluminum deck and an attractively thin profile. Its major feature is its ability to remember a connection for up to three devices. A switch at the top right allows you to shift among 2.4GHz wireless and two Bluetooth channels. Aside from that, this keyboard is no-frills. It lacks backlighting, and the tactile feedback from the keys is very shallow. The typing angle isn't adjustable.
The arc-shaped mouse is designed to fit the palm of your hand. Its optical sensor is located along the front edge. In addition to the two main mouse buttons and the scroll wheel, it also has one button on either side. The mouse is usable overall, but it isn't designed for larger hands. Overall, we'd probably pass on this keyboard/mouse combo at its current price. You can do better from third parties for the money.Sky-High Parts: Xeon and Quadro Power
In the Precision 5820 Tower, Dell offers a variety of Intel Xeon W-class processors. Introduced in the second half of 2017, these CPUs sport four to 18 cores. The 10-core Xeon W-2155 CPU in their review model effortlessly powers through any task. Each core runs at 3.3GHz, with the capability to Turbo Boost up to 4.5GHz. The top-end processor choice is the 18-core Xeon W-2195, although it's clocked lower; each core runs at just 2.3GHz, with a Turbo Boost up to 4.3GHz. As noted earlier, you can step up to the Precision 7820 for dual CPU support if you need even more power.
Now, if you know you need a Xeon chip, you certainly have your business-specific reasons. A major one mandating why you'd spend extra for a Xeon is if you need support for Error Correcting Code (ECC) memory. This is mainly a concern in situations where not a single bit in calculations can be wrong, such as in certain scientific, architectural, financial, or aeronautical calculations. Another is sheer uptime engineering; Xeons are designed for constant cranking in environments such as high-demand servers or render stations. If that's not key for you, and you simply need heavy multi-threaded power, it would be significantly cheaper to stick with a consumer-class Core i7 chip, available in Dell's OptiPlex business desktops. (Intel's enthusiast-minded Core X-Series is also an option.)
Beyond ECC for professional users, of course, are ISV certifications. These are stamps of approval, of a sort, for specific professional-grade applications in fields such as media production, engineering, and architecture, which guarantee that the hardware will run up to snuff with the software. With high-end workstations like this one, it's a complex interplay between the system maker and the relevant software makers. Dell's list of partners for its Precision workstations can be found here, and it includes a list of partners that includes expected players like Adobe, Autodesk, Avid, and Dassault Systems. (Dell also offers a software-level optimization service that tweaks the workstation for specific ISV-certified applications.)
In many cases, specific ISV suitability ties in to graphics horsepower, and Dell offers the Precision 5820 with a formidable assortment of AMD Radeon Pro and Nvidia Quadro professional graphics cards. This tower can accept two of them, with each PCIe x16 slot supporting up to 300-watt graphics cards. The test unit I was loaned for review has one highly potent Quadro P4000 with 8GB of memory. Combined with the Xeon W-2155 CPU and 64GB of memory, this Precision 5820 configuration is fit to handle any demanding creative task with aplomb, including rendering CGI imagery and authoring virtual-reality simulations.
The standard warranty on the Precision 5820 is three years with onsite service. Up to a five-year warranty with next-day onsite service is available. Windows 10 Pro for Workstations, required for harnessing the 10-core CPU in their review unit, is cleanly installed, with just a few Dell apps present.
Cooling isn't an issue for the Precision 5820. Two internal 80mm fans, a 120mm fan, and the two fans in the power supply draw cool air in the front and send it out the rear. The fans are well-behaved, running quietly during their performance tests.Let's Fire Up the Big Iron
It goes unsaid that the Precision 5820 has little trouble with their benchmark suite. Anything in need of CPU power won't find a 10-core Xeon W-2155 CPU lacking, although there are faster machines out there.
When you're looking at raw CPU grunt, offerings from Intel in its Core X-Series and AMD in its Ryzen Threadripper line serve up well more than 10 cores and 20 addressable threads. For one, the overclocked 18-core Intel Core i9-7980XE Extreme Edition (a $2,000 CPU) in the Falcon Northwest Talon (2018) more than doubles the Precision 5820's score in the CPU-centric Cinebench R15 benchmark, and it is predictably faster in the video-encoding test Handbrake.
Another example is from the AMD side of the aisle. The 16-core AMD Ryzen Threadripper 1950X in the Alienware Area-51 Threadripper Edition also exceeds the Precision 5820's score, but it falls behind in Handbrake. Compared to the old Haswell-era 10-core Xeon E5-2687W v3 in the Precision 5810, however, their Precision 5820 is significantly faster. It's noteworthy that, excluding the Dells, the other machines in this comparison are for gaming, not professional work.
See How They Test Desktops
The Nvidia Quadro P4000 in the Precision 5820 takes a back seat in these entertainment-driven benchmarks, especially next to the pair of GeForce GTX 1080 Ti graphics cards in the Velocity Micro Raptor Z95 (2017). The Quadro's strength lies in its professional application support; it's designed for rendering and complex situations using applications such as AutoCAD. As noted, the Precision 5820 can be configured with up to dual Quadro or AMD Radeon Pro GPUs for the ultimate performance.A Few Workstation-Specific Tests
We also subjected the Precision 5820 to several workstation-minded tests, including Cinebench R15 OpenGL and POV-Ray 3.7 to test its professional hardware.
Its 157-frame-per-second (fps) showing in Cinebench outpaced that of the MSI WT73 Mobile Workstation, which was equipped with a Quadro P5000 (albeit the mobile version). Thanks to its 10-core CPU, the Precision 5820 did remarkably well in the CPU-dependent POV-Ray 3.7 test, completing the all-cores test run in a time of just 61.3 seconds. Although not an apples-to-apples comparison, the Core i7-7820HK quad-core CPU in the aforementioned MSI notebook stood at 160.6 seconds. In the same benchmark, the Dell also achieved 4,107 pixels per second (pps), handily outpacing the 1,622 pps score from the MSI.
I also ran the Creo, Maya, and SolidWorks viewsets in SPECviewperf, with the Dell tower ringing up at 150fps, 217fps, and 151fps, respectively. (See much more about SPECviewperf here; it's predominantly a workstation-graphics test that simulates a variety of pro-application workloads.) PC Labs had not reviewed a desktop workstation with the Quadro P4000 or P5000 to date; the closest thing was the mobile version of the Quadro P5000 in the aforementioned MSI workstation laptop. The results of two of the sets were close enough to call a virtual tie; the Maya test, however, saw a twofold advantage for the desktop P4000 card.Sky-High Limits, Just Mind Your Budget
The Precision 5820 Tower is a highly capable business workstation. Their approaching-$6,000 test unit is several times the price of the base system, but it is far from the most expensive configuration you can order. Nonetheless, the 10-core Intel Xeon W-2155 processor, Nvidia Quadro P4000 graphics card, and 64GB of quad-channel ECC memory made short work of their benchmark tests. On top of all that, it runs quietly and has excellent expandability.
If you need professional hardware to get the job done, consider the Precision 5820 Tower—in your specific, custom config, suited to your apps of choice—as your partner in crime. Just keep the options within reason for what you do, or you'll need to plan a bank heist before you can hoist this weighty power tower to your desk.Dell Precision 5820 Tower
