SCO UNIXWARE 7 NONSTOP CLUSTERS

SCO, Compaq ServerNet-less clusters

The Santa Cruz Operation is introducing a edition of Non stop Clusters for Intel packing containers that does not need Compaq's proprietary ServerNet interconnects.

needing handiest two 100Mbps Ethernet adaptors to allow heartbeat communications, and in a position to run on bog ordinary white box PCs, this latest edition of NSC is probably the most cost-effective true datacentre type clustering that now they have viewed on the hunble computing device.

SCO is asking $7799 for a two-node bundle of UnixWare NSC 7.1.1+IP. UnixWare NSC is presently bought through Compaq and licensee Fujitsu Siemens for clusters of up to 6 nodes (that's forty eight CPUs the use of normal Intel Profusion eight-way bins) but ServerNet is mandatory. No greater, although.

SCO does suggest that bigger configurations than two nodes need to use ServerNet switches. As earlier than, NSC gives a single device graphic for administrative applications, and requires no changes to applications. as an example, Oracle 8i want simplest be kicked off from a customized script to turn into cluster conscious. This doesn't observe to Oracle Parallel Server, which isn't supported by way of UnixWare NSC.

It marks whatever thing of a metamorphosis of heart for Compaq, too. They questioned if Q hadn't let one among its crown jewels slip into the fingers of field shifters? No, SCO says, there'll be joint promotional undertaking and it widens the expertise base for NSC.

through the conclusion of the 12 months UnixWare NSC will help as much as sixteen nodes (128 CPUs) and Gigabit Ethernet. the new two node, IP-based NSC is as a result of ship on July.

despite some slips in its roadmap, UnixWare remains method ahead of different Intel clusters. Microsoft looks like leaving Wolfpack, aka Microsoft Cluster Server, the place it is on the mortuary slab, and becoming a member of solar in an SMP scaling race. home windows 2000 DataCenter version will scale to 2 or four nodes. This isn't the heady stuff it changed into promising 4 or five years ago.

What's worse is that Oracle has no intention of producing a cluster-mindful database for home windows 2000, and Microsoft's own applications are most effective simply getting circular to be cluster mindful, and best in ingredients.

Open source Linux clustering for actual database and TP jobs abounds, with SGI and SuSE co-ordinating work on porting SGI's FailSafe to Linux. And work on a shared-every thing, VAX-like distributed lock supervisor may still undergo fruit against the conclusion of the 12 months. this could ultimately be the lynchpin for cluster file methods, until FailSafe - which is additionally in keeping with a DLM - hasn't scooped up the mindshare via then. ®

UnixWare NonStop Clusters is an example of Compaq proposing its purchasers with the maximum efficiency and most scalable Intel-based techniques within the trade.”

Compaq first delivered the NonStop Cluster software know-how to fulfill the needs of its Telecommunications shoppers, on its Compaq ProLiant server-primarily based Integrity XC platform in January 1998. Compaq’s Tandem Division continues to promote NonStop Clusters direct to the telecommunications valued clientele.

UnixWare NonStop Clusters expertise provides both high availability and superb system scalability. every node of a cluster can feature independently of alternative nodes; or purposes can take competencies of load balancing, system and software fail-over and process migration all over the cluster. purposes can run unmodified in a cluster, or effective cluster-mindful functions may also be created. These may consist of parallel databases, web servers and multi-tiered purposes like on line Transaction technique (OLTP) and business useful resource Planning (ERP).

AMORE allows the retrieval of web documents similar to a user-specified image or keywords. A web crawler is used to gather relevant documents from the Internet and COIR is then used to index all of the images contained and referenced in those documents. COIR retrieves similar images based on attributes such as color, shape and texture. AMORE also incorporates a heuristic algorithm to assign keywords to images retrieved, which allows users to specify a keyword to search for images on the web.

SYMANTEC INTROS VISUAL CAFE FOR JAVA, ENTERPRISE EDITION

Cupertino, CA — As Jon Cornetto reported for InfoWorld Electric, Symantec has introduced Visual Cafe for Java, Enterprise Suite, which will reportedly allow developers to build and deploy distributed Java applications on multiple platforms. The new environment is designed to look and feel like the company’s single-tier development tools, sporting a drag-and-drop interface and the usual collection of wizards and class browsers — plus an interaction editor that allows visual implementation of JavaBeans components.

The tool automatically tracks each piece of a distributed application as it is being built so that the developer sees the application as a whole, instead of fragmented parts. This tracking is done from one location to allow distributed debugging from one machine. Based on an open platform, the new product supports a wide variety of middle-tier application servers and object request brokers. This platform independence allows debugging across multiple platforms and virtual machines, including Sun Solaris, HP-UX, IBM AIX, and Windows NT. For more information visit http://www.symantec.com

COMPAQ SHIPS PROLIANT SERVERS WITH PENTIUM II XEON PROCESSORS

DR. DOBBS JOURNAL MAKES VISUAL PROGRAMMING FREELY AVAILABLE

San Mateo, CA — Although true visual programming has been touted as the future of software development, few programmers have had experience with it, let alone know what it is. Addressing this need, Dr. Dobb’s Journal magazine is releasing with its September 1998 issue a special version of the Prograph visual programming language. Prograph is a true visual language from Pictorius, Inc. (Halifax, Nova Scotia) which allows programmers to create executable software by directly manipulating graphical representations of programs. Most available software tools that call themselves “visual” are traditional text-based languages with a graphical integrated development environments.

Get IT Done: Use server clustering as a high availability solution

Learn how clustering can benefit your network as well as how to set it up.

High availability (HA) is the buzzword of the day, but what does it mean? Often applied to Web services, it refers to the capability of a network service to “be there when you need it”—regardless of hardware or software problems.

HA may sound suspiciously similar to an old, more familiar friend: fault tolerance. And the two have something else in common: Both can be achieved by implementing intentional, carefully planned redundancy in a system. Fault-tolerant disk solutions, such as RAID, use multiple disks that are managed together and can continue to function after the failure of one disk. Likewise, the most popular means of providing HA is clustering—the use of multiple servers, managed as an entity that will continue to function if one server goes down.

In this Daily Feature, they will take a look at what server clustering is, how to determine whether you need it, and what it can do for your network.

What is server clustering?A server cluster, also called a server farm, consists of two or more computers that function, are managed, and appear to the network users as a single entity. Each of the computers that belong to the cluster is called a node.

What a server cluster doesClustering makes mission-critical applications available when needed. These include:

  • Web services
  • Databases, accounting programs, and other essential business applications
  • File and print services
  • E-mail and other communication services
  • Cluster typesServers can be clustered to provide only fault tolerance, or the cluster can be configured to provide for high performance by spreading the processing load across multiple machines. In the second model, the nodes are all online simultaneously. In the first, which they will focus on here, only one node, called the primary node, is online. The secondary node “sits and waits” unless or until the primary node fails, at which point it takes over and continues to provide the resources. The whole process is transparent to the users. Let’s look at the details of this process.

    How clustering worksTo implement clustering, you must have at least two servers that are connected to the same network and running clustering software (discussed later in this article). Depending on the method used, you may also need a shared disk or disk array, to which both servers are connected.

    Disk sharingThere are three methods of making the information on disk (application programs, user data) available to all the servers in the cluster. The earliest method was called shared disks, which required special cables and switches. The biggest drawback was the necessity for applications to be modified for use in these situations.

    Another method uses disk mirroring. Each of the servers has a separate physical disk. Software copies all data written to the disk on one server to the disks of the other nodes. Mirrored disks provide great redundancy but are somewhat difficult to manage. The biggest problem is that at some time before the data is replicated to the other disks, the nodes will not all have identical data. If a failure occurred exactly at that point, there would be a problem.

    Microsoft and a number of other cluster services vendors use a method called shared nothing. Every node has its own disks, but if a failure occurs, the clustering software can “transfer ownership” of a disk. It has the same advantages as shared disks, but does not require special applications.

    Your beating heartAll this is very well and good, but in order for a clustering solution to offer HA, the software must be able to automatically detect the failure of the primary node and transfer its responsibilities to a secondary node, without human intervention.

    A popular means of detecting the “death” of a cluster node is by checking its “heartbeat.” The heartbeat is a high-speed link between the cluster members, over which they exchange status information and monitor one another’s activity. Each node typically has a NIC that is used for this connection (called “heartbeat traffic”) in addition to the NIC with which it connects to the network.

    Do they have a quorum?Another important issue, especially when there are more than two nodes in a cluster, is which node “owns” a resource and which one will take over providing that resource if the owning node fails.

    One way to handle this, as implemented by Microsoft’s cluster services, is the concept of a quorum resource (a shared physical disk). Only one node can own this resource at a given time, but any node in the cluster has access to it. The disk used as the quorum resource must support hardware-based lockout. This disk is used to store the cluster log and database for cluster management.

    Failover and failbackIt is important to understand the terminology associated with clustering before you attempt to evaluate your clustering options or implement a clustering solution.

    Failover occurs when a cluster resource fails. If it is a single application that fails, the cluster service tries to restart it—first on the same node and then, if that doesn’t work, on another node. If the primary node goes offline, the cluster software will failover all the applications. This occurs automatically when the cluster software detects the failure of a node or application. Administrators can also manually initiate the failover process.

    Failback refers to the ability of the cluster software, after a failover, to restore the resources back to the node that was originally hosting them when that node comes back online.

    Clustering software allows administrators to set policies governing whether failback is allowed.

    Clustering softwareThere are a number of vendors providing clustering software. Some operating system vendors include clustering support in their high-end network operating systems. Third-party vendors offer add-on clustering solutions. The following are only a few of the many server-clustering implementations available.

    Microsoft cluster servicesMicrosoft released their clustering solution, code name “Wolfpack,” as Microsoft Cluster Server (MSCS) with the Windows NT 4.0 Enterprise Edition. It also provided an API for the cluster service, which allowed for third-party applications that would be able to failover or restart to another cluster node when the primary node failed.

    Windows 2000 Advanced Server and Datacenter Server include an updated and improved version of MSCS, called Windows 2000 Cluster Services. Advanced Server supports two-node failover, and Datacenter Server supports four-node failover. IP load balancing and COM-based applications are supported, as well.

    More on MSFor more information about Microsoft’s cluster services, see the Microsoft site for NT or Windows 2000. Novell cluster servicesNovell NetWare 5.x supports clustering, using the NDS-enabled Novell Cluster Services. Up to 32 nodes can be deployed in a server cluster, and the product ensures distributed failover, even if multiple nodes fail. This keeps any individual node from becoming overloaded.

    Clients are transparently reconnected to a remaining server when the node to which they are connected fails, and users’ mapped drives are even preserved. Novell uses what it calls “split-brain detection” to ensure that more than one surviving node will not attempt to mount the same disk volume of a node that has failed. The Cluster Interconnect Protocol (CIP) is used to verify node status.

    More on NovellFor more information about Novell’s Cluster Services, see the Novell Web site. NSI Software’s GeoClusterGeoCluster is a third-party product that offers some advantages over other clustering implementations. GeoCluster is integrated with MSCS and provides a model in which each node has its own copy of all data, with real-time replication that occurs on a continuous basis over a LAN, VLAN, or SAN connection. Servers do not have to be located in close geographic proximity to one another.

    For more information about GeoCluster, see the NSI Software Web site.

    Cluster services for Linux and UNIXThere are many clustering products available to provide HA networking for Linux and UNIX servers, as well. These include:

    ConclusionIs server clustering for you? Many of the popular clustering solutions are expensive, and the requirement for redundant hardware adds to the cost. However, if you have network applications that absolutely, positively must be available on a daily basis, downtime can have a huge impact on your bottom line.

    Evaluate the estimated loss in revenue and productivity of having your mission-critical applications and data offline and compare it to the cost of implementing a clustering solution. You may find that just a few days or hours without those services could equal or exceed the cost of creating a HA solution for your network. Not to mention the value of your peace of mind: priceless.
