IBM manual Z10 EC Model

z10 EC Model

The z10 EC has been designed to offer high performance and effi cient I/O structure. All z10 EC models ship with two frames: an A-Frame and a Z-Frame, which together sup- port the installation of up to three I/O cages. The z10 EC will continue to use the Cargo cage for its I/O, supporting up to 960 ESCON® and 256 FICON channels on the Model E12 (64 I/O features) and up to 1,024 ESCON and 336 FICON channels (84 I/O features) on the Models E26, E40, E56 and E64.

To increase the I/O device addressing capability, the I/O subsystem provides support for multiple subchannels sets (MSS), which are designed to allow improved device connectivity for Parallel Access Volumes (PAVs). To sup- port the highly scalable multi-book system design, the z10 EC I/O subsystem uses the Logical Channel Subsystem (LCSS) which provides the capability to install up to 1024 CHPIDs across three I/O cages (256 per operating system image). The Parallel Sysplex Coupling Link architecture and technology continues to support high speed links pro- viding effi cient transmission between the Coupling Facility and z/OS systems. HiperSockets provides high-speed capability to communicate among virtual servers and logi- cal partitions. HiperSockets is now improved with the IP version 6 (IPv6) support; this is based on high-speed TCP/ IP memory speed transfers and provides value in allowing applications running in one partition to communicate with applications running in another without dependency on an external network. Industry standard and openness are design objectives for I/O in System z10 EC.

The z10 EC has fi ve models offering between 1 to 64 pro- cessor units (PUs), which can be confi gured to provide a highly scalable solution designed to meet the needs of both high transaction processing applications and On Demand Business. Four models (E12, E26, E40 and E56) have 17 PUs per book, and the high capacity z10 EC Model E64 has one 17 PU book and three 20 PU books. The PUs can be characterized as either CPs, IFLs, ICFs, zAAPs or zIIPs. An easy-to-enable ability to “turn off” CPs or IFLs is available on z10 EC, allowing you to purchase capacity for future use with minimal or no impact on software billing. An MES feature will enable the “turned off” CPs or IFLs for use where you require the increased capacity. There are a wide range of upgrade options avail- able in getting to and within the z10 EC.

The z10 EC hardware model numbers (E12, E26, E40, E56 and E64) on their own do not indicate the number of PUs which are being used as CPs. For software billing pur- poses only, there will be a Capacity Identifi er associated with the number of PUs that are characterized as CPs. This
