IBM System z10 is the latest line of IBM mainframes. It was announced on February 26, 2008, and represents the first model powered by the z10 quad core processing engines.
There are five models of z10 Enterprise Class, the E12, E26, E40, E56, and E64, each of machine type 2097. The machines are powered by multi-chip modules (MCMs) called "books" of Processing Units (PUs). The E12, E26, E40, and E56 have books with 17 PUs each, and the E64 has one book with 17 PUs and three with 20 PUs.
The number of configurable PUs is indicated in the model designation (e.g., the E26 have 26 configurable PUs). Depending on model these PUs can be configured as Central Processors (CPs), System Assist Processors (SAPs), Integrated Facility for Linux (IFL) processors, z Application Assist Processors (zAAPs), z10 Integrated Information Processors (zIIPs), or Internal Coupling Facility (ICF) processors.
The base system comes with 16 GiB of memory, expandable up to 1.5 TiB for the E56 and E64 systems. In addition to customer specified memory, all systems always come with a 16 GiB dedicated Hardware System Area, off limits to customer memory. All systems also come with decimal floating-point and cryptographic units in each core.
The System z10 adds 192-bit and 256-bit Advanced Encryption Standard (AES) in addition to the 128-Bit AES support already available on the z9.
The z10 Enterprise Class (EC) will deliver an estimated 50% higher capacity per PU than its predecessor the System z9 EC, and approximately 70% more for the whole 64-way z10 EC E64 system compared to the previous 54-way z9 EC S54 system.
It will support the new z/OS v1.10 operating system which will be released in September 2008.
