Z10 Ec Models - IBM System z10 EC Reference Manual

The z10 EC has been designed to offer high performance
and efficient I/O structure. All z10 EC models ship with
two frames: an A-Frame and a Z-Frame, which together
support the installation of up to three I/O cages. The z10
EC will continue to use the Cargo cage for its I/O, support-
ing up to 960 ESCON and 256 FICON
®
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 efficient 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.

z10 EC Models

The z10 EC has five models offering between 1 to 64 pro-
cessor units (PUs), which can be configured 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)
channels on the 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.
