PUs defi ned as Internal Coupling Facilities (ICFs), Inte-
grated Facility for Linux (IFLs), System z10 Application
Assist Processor (zAAPs) and System z10 Integrated Infor-
mation Processor (zIIPs) are no longer grouped together in
one pool as on the IBM eServer
™
zSeries
®
890 (z890), but
are grouped together in their own pool, where they can be
managed separately. The separation signifi cantly simpli-
fi es capacity planning and management for LPAR and can
have an effect on weight management since CP weights
and zAAP and zIIP weights can now be managed sepa-
rately. Capacity BackUp (CBU) features are available for
IFLs, ICFs, zAAPs and zIIPs.
LAN connectivity has been enhanced with the introduction
of the third generation of Open Systems Adapter-Express
(OSA-Express3). This new family of LAN adapters have
been introduced to reduce latency and overhead, deliver
double the port density of OSA-Express2 and provide
increased throughput. The z10 BC continues to support
OSA-Express2 1000BASE-T and GbE Ethernet features,
and
supports IP version 6 (IPv6) on HiperSockets. While
OSA-Express2 OSN (OSA for NCP) is still available on
System z10 BC to support the Channel Data Link Control
(CDLC) protocol, the OSA-Express3 will also provide this
function.
Additional channel and networking improvements include
support for Layer 2 and Layer 3 traffi c, FCP management
facility for z/VM and Linux for System z, FCP security
improvements, and Linux support for HiperSockets IPv6.
STP enhancements include the additional support for NTP
clients and STP over Infi niBand links.
Like the System z9 BC, the z10 BC offers a confi gurable
Crypto Express2 feature, with PCI-X adapters that can
be individually confi gured as a secure coprocessor or
an accelerator for SSL, the TKE workstation with optional
Smart Card Reader, and provides the following CP Assist
for Cryptographic Function (CPACF):
• DES, TDES, AES-128, AES-192, AES-256
• SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
• Pseudo Random Number Generation (PRNG)
z10 BC is designed to deliver the industry leading Reli-
ability, Availability and Serviceability (RAS) customers
expect from System z servers. RAS is designed to
reduce all sources of outages by reducing unscheduled,
scheduled and planned outages. Planned outages are
further designed to be reduced by reducing preplanning
requirements.
z10 BC preplanning improvements are designed to avoid
planned outages and include:
• Reduce pre-planning to avoid POR
– “Fixed” HSA amount
– Dynamic I/O enabled by default
– Add Logical Channel Subsystem (LCSS)
– Change LCSS Subchannel Sets
– Add/Delete logical partitions
• Reduce pre-planning to avoid LPAR deactivate
– Change partition logical processor confi guration
– Change partition crypto coprocessor confi guration
• CoD – Flexible activation/deactivation
• Elimination of unnecessary CBU passwords
• Enhanced Driver Maintenance (EDM) upgrades
– Multiple “from” sync point support
– Improved control of channel LIC levels
• Plan ahead memory
• Concurrent I/O drawer add/repair
