Current Version: Discontinued Product

Editions:

Data Center Edition
Enterprise Edition
Departmental Edition
Business Edition
Base Edition
Non-Stop Clusters Edition (NSC)

Note: SCO has renamed OpenUnix 8 back to UnixWare 7. The most current version of which is UnixWare 7.1.3. It provides a return to the UnixWare name that is trusted around the world as the premier UNIX Operating System for the Intel(R) Architecture. UnixWare 7.1.3 continues to be the right choice for companies who place a high value on the scalability, reliability and security inherent in UNIX technology based systems. While continuing the tradition of backwards compatibility for UnixWare applications, UnixWare 7.1.3 also runs Linux applications that comply with the LSB specification. Thus both UnixWare and Linux applications can run simultaneously on the same trusted SVR5 kernel. This dual capability of UnixWare 7.1.3 is unmatched in the industry.

The following information on UnixWare 7, NSC Edition is being left here for informational purposes only.

SCO UnixWare Non-Stop Clusters Edition (Discontinued)

UnixWare 7 NonStop Clusters Release 7.1.1+IP, the newest release of SCO's award winning high availability software, significantly broadens hardware support, making it easier and less expensive to deploy the most advanced clustering software for Intel® systems. This release features standard IP as the interconnect, removing the need for any proprietary hardware. All standard Intel processor-based servers can now be easily built into powerful clustered systems at an affordable price. SCO has now opened the market for enterprise-class clustering into small and medium sized businesses.

UnixWare 7 NonStop Clusters provides totally dependable access to your business-critical data and applications. UnixWare 7 NonStop Clusters software links together individual "nodes" -- whole computers, each running its own copy of the operating system kernel - such that they act and appear as a single system. If one node goes down, or if an application fails on a particular node, processes are actively migrated and resumed. If a node needs to be taken off-line, for maintenance or upgrading, the rest of the cluster continues to service its users. Other nodes in the cluster take care of new connections or instances of applications. In this way, downtime -- planned or unplanned -- is eliminated.

On its own, UnixWare 7 blends the performance, reliability, availability and scalability benefits of UNIX systems with the economies of Intel processors. Years ahead of any other Intel processor-based clustering technology, UnixWare 7 NonStop Clusters lets you exploit these benefits to a whole new level.

UnixWare 7 NonStop Clusters'; Single System Image (SSI) improves the functionality of UNIX clusters by reducing the visibility of the underlying cluster implementation. This actually reduces the associated management and application design complexity. With SSI, multiple cluster nodes appear as a single system to users, administrators, and applications.

Unique fail-over technology means individual computers or nodes inside the cluster automatically take over should another node fail. This yields exceptionally high availability, minimizing or even eliminating expensive downtime. In normal operation, processes are shared among nodes automatically, dynamically balancing the load. Although the cluster is made up of individual nodes, applications, users and administrators see a single system. This fundamental design philosophy brings close to 1:1 scalability -- dramatic performance and scalability for networking, applications and transaction throughput.

Most UnixWare applications will run unchanged. However, applications can be optimized for UnixWare 7 NonStop Clusters. Administrators can write simple scripts to better take advantage of cluster extensions for controlled availability and scalability. Software vendors can adapt their standard UnixWare 7 applications to take full advantage of its availability and scalability features, straight out of the box.

Unlike traditional high-availability and scalability products, UnixWare 7 NonStop Clusters is a true Single System Image technology where all nodes of a cluster appear and function transparently as a single system to applications, devices, users and administrators. SSI means the whole cluster can be managed from a single console, using familiar, standard UNIX system commands.

UnixWare 7 blends the performance, reliability, availability and scalability benefits of UNIX systems with the economies of Intel processors. Years ahead of other Intel processor-based clustering technology, UnixWare 7 NonStop Clusters lets the enterprise exploit these benefits to a whole new level.

Features:

2 - 12 node single system image clusters on standard Intel processor-based servers
High availability through fail-over between nodes
Dynamic load balancing and process migration between nodes
Most UnixWare applications can run unmodified (cluster unaware) and can be optimized to exploit cluster features
Single System Image (SSI) file systems, devices, applications are accessible transparently across the cluster
File systems and devices accessible transparently across the entire cluster

Benefits:

High availability -- when downtime is intolerable, eliminate it
Price/performance -- price/performance benefits of UNIX Systems on Intel processors
Lower cost of management -- manage all nodes in the cluster from a single console
Power when you need it -- add a node, add more power without downtime
Application scalability -- linear scaling of some applications surpassing 95% efficiency for each additional node
Huge range of applications -- most UnixWare applications run better unchanged

Technical Specifications:

UnixWare 7 NonStop Clusters (Release 7.1.1) requires certification of complete cluster configurations. Please contact us for the current supported hardware list. As guidance, these configurations include:
