z/Architecture

The z10 BC continues the line of upward compatible main- frame processors and retains application compatibility since 1964. The z10 BC supports all z/Architecture®-com- pliant Operating Systems. The heart of the processor unit is the IBM z10 Enterprise Quad Core processor chip run- ning at 3.5 GHz, designed to help improve CPU intensive workloads.

The z10 BC, like its predecessors, supports 24, 31, and 64-bit addressing, as well as multiple arithmetic for- mats. High-performance logical partitioning via Processor Resource/Systems Manager™ (PR/SM™) is achieved by industry-leading virtualization support provided by z/VM.

A change to the z/Architecture on z10 BC is designed

to allow memory to be extended to support large (1 mega- byte (MB)) pages. Use of large pages can improve CPU utilization for exploiting applications.

Large page support is primarily of benefi t for long-running applications that are memory-access-intensive. Large page is not recommended for general use. Short-lived processes with small working sets are normally not good candidates for large pages.

Large page support is exclusive to System z10 running either z/OS or Linux on System z.

z/Architecture operating system support

Delivering the technologies required to address today’s IT challenges also takes much more than just a server; it requires all of the system elements to be working together. IBM System z10 operating systems and servers are designed with a collaborative approach to exploit each other’s strengths.

The z10 BC is also able to exploit numerous operating sys- tems concurrently on a single server, these include z/OS, z/VM, z/VSE, z/TPF, TPF and Linux for System z. These operating systems are designed to support existing appli- cation investments without anticipated change and help you realize the benefi ts of the z10 BC. z10 BC—the new business equation.

z/OS

August 5, 2008, IBM announced z/OS V1.10. This release of the z/OS operating system builds on leadership capa- bilities, enhances time-tested technologies, and leverages deep synergies with the IBM System z10 and IBM System Storage™ family of products. z/OS V1.10 supports new capabilities designed to provide:

•Storage scalability. Extended Address Volumes (EAVs) enable you to defi ne volumes as large as 223 GB to relieve storage constraints and help you simplify storage management by providing the ability to manage fewer, large volumes as opposed to many small volumes.

•Application and data serving scalability. Up to 64 engines, up to 1.5 TB per server with up to 1.0 TB of real memory per LPAR, and support for large (1 MB) pages on the System z10 can help provide scale and performance for your critical workloads.
