IBM Z10 BUISNESS CLASS Z10 BC - Manual (Page 15)

Timed Interconnect Multiplexer (STI-MP) card. There are
two types of HCA fanout cards: HCA2-C is copper and
is always used to connect to I/O (IFB-MP card) and the
HCA2-O which is optical and used for customer Infi niBand
coupling.
The z10 BC has been designed to offer high performance
and effi cient I/O structure. The z10 BC ships with a single
frame: the A-Frame which supports the installation of up
to four I/O drawers. Each drawer supports up to eight I/O
cards, four in front and four in the rear, providing support
for up to 480 channels (32 I/O features).
To increase the I/O device addressing capability, the I/O
subsystem has been enhanced by introducing support
for multiple subchannels sets (MSS), which are designed
to allow improved device connectivity for Parallel Access
Volumes (PAVs). To support the highly scalable system
design, the z9 BC I/O subsystem uses the Logical Chan-
nel SubSystem (LCSS) which provides the capability to
install up to 512 CHPIDs across the I/O drawers (256 per
operating system image). The Parallel Sysplex Coupling
Link architecture and technology continues to support
high speed links providing effi cient transmission between
the Coupling Facility and z/OS systems. HiperSockets
provides high speed capability to communicate among
virtual servers and logical partitions. HiperSockets is now
improved with the IP version 6 (IPv6) support; this is based
on high speed TCP/IP memory speed transfers and pro-
vides value in allowing applications running in one partition
to communicate with applications running in another with-
out dependency on an external network. Industry standard
and openness are design objectives for I/O in z9 BC.
The z10 BC has one model, the E10, (Machine Type 2098)
offering between 1 to 10 processor units (PUs), which
can be confi gured to provide a highly scalable solution
designed to meet the needs of both high transaction pro-
cessing applications and On Demand business. The PUs
can be characterized as either CPs, IFLs, ICFs, zAAPs,
zIIPs or option SAPs. An easy-to-enable ability to “turn
off” CPs or IFLs is available on z10 BC, 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 BC.
The z10 BC hardware model number (E10) on its own does
not indicate the number of PUs which are being used as
CPs. For software billing purposes only, there will be a
Capacity Indicator associated with the number PUs that
are characterized as CPs. This number will be reported
by the Store System Information (STSI) instruction for soft-
ware billing purposes only. There is no affi nity between the
hardware model and the number of CPs.
z10 BC capacity identifi ers
nxx, where n = subcapacity engine size and xx = number
of CPs
• Total 130 Capacity Indicators for “software settings”
• A00 for systems with IFL(s) or ICF(s) only.
Memory DIMM sizes: 2 GB and 4 GB
• Maximum physical memory: 256 GB per system
– Minimum physical installed = 16 GB of which 8 GB is
for Fixed HSA
• For 8 to 32, 4 GB increments, from 32 to 248, 8 GB
increments
