Availability Digest
the Availability Digest Parallel Sysplex – Fault Tolerance from IBM April 2008 IBM’s Parallel Sysplex, HP’s NonStop server, and Stratus’ ftServer are today the primary industry fault-tolerant offerings that can tolerate any single failure, thus leading to very high levels of availability. The Stratus line of fault-tolerant computers is aimed at seamlessly protecting industry- standard servers running operating systems such as Windows, Unix, and Linux. As a result, ftServer does not compete with the other two systems, Parallel Sysplex and NonStop servers, which do compete instead in the large enterprise marketplace. In this article, we will explore IBM’s Parallel Sysplex and its features that address high availability. IBM’s Parallel Sysplex IBM’s Parallel Sysplex systems are multiprocessor clusters that can support from two to thirty-two mainframe nodes (typically S/390 or zSeries systems).1 A Parallel Sysplex system is nearly linearly scalable up to its 32-processor limit. A node may be a separate system or a logical partition (LPAR) within a system. The nodes do not have to be identical. They can be a mix of any servers that support the Parallel Sysplex environment. The nodes in a Parallel Sysplex system interact as an active/active architecture. The system allows direct, concurrent read/write access to shared data from all processing nodes without sacrificing data integrity. Furthermore, work requests associated with a single transaction or database query can be dynamically distributed for parallel execution based on available processor capacity of the nodes in the Parallel Sysplex cluster. Parallel Sysplex Architecture All nodes in a Parallel Sysplex cluster connect to a shared disk subsystem.
