IBM Z10 EC - Manual (Page 13)

z10 EC preplanning improvements are designed to avoid
planned outages and include:
• Flexible Customer Initiated Upgrades
• Enhanced Driver Maintenance
– Multiple “from” sync point support
• Reduce Pre-planning to avoid Power-On-Reset
– 16 GB for HSA
– Dynamic I/O enabled by default
– Add Logical Channel Subsystems (LCSS)
– Change LCSS Subchannel Sets
– Add/delete Logical partitions
• Designed to eliminate a logical partition deactivate/
activate/IPL
– Dynamic Change to Logical Processor Defi nition –
z/VM 5.3
– Dynamic Change to Logical Cryptographic Coproces-
sor Defi nition – z/OS ICSF
Additionally, several service enhancements have also
been designed to avoid scheduled outages and include
concurrent fi rmware fi xes, concurrent driver upgrades,
concurrent parts replacement, and concurrent hardware
upgrades. Exclusive to the z10 EC is the ability to hot swap
ICB-4 and Infi niBand hub cards.
Enterprises with IBM System z9 EC and IBM z990 may
upgrade to any z10 Enterprise Class model. Model
upgrades within the z10 EC are concurrent with the excep-
tion of the E64, which is disruptive. If you desire a con-
solidation platform for your mainframe and Linux capable
applications, you can add capacity and even expand your
current application workloads in a cost-effective manner. If
your traditional and new applications are growing, you may
fi nd the z10 EC a good fi t with its base qualities of service
and its specialty processors designed for assisting with
new workloads. Value is leveraged with improved hardware
price/performance and System z10 EC software pricing
strategies.
The z10 EC processor introduces IBM System z10
Enterprise Class with Quad Core technology, advanced
pipeline design and enhanced performance on CPU inten-
sive workloads. The z10 EC is specifi cally designed and
optimized for full z/Architecture compatibility. New features
enhance enterprise data serving performance, industry
leading virtualization capabilities, energy effi ciency at
system and data center levels. The z10 EC is designed
to further extend and integrate key platform characteris-
tics such as dynamic fl exible partitioning and resource
management in mixed and unpredictable workload envi-
ronments, providing scalability, high availability and Quali-
ties of Service (QoS) to emerging applications such as
WebSphere, Java and Linux.
With the logical partition (LPAR) group capacity limit on
z10 EC, z10 BC, z9 EC and z9 BC, you can now specify
LPAR group capacity limits allowing you to defi ne each
LPAR with its own capacity and one or more groups of
LPARs on a server. This is designed to allow z/OS to
manage the groups in such a way that the sum of the
LPARs’ CPU utilization within a group will not exceed the
group’s defi ned capacity. Each LPAR in a group can still
optionally continue to defi ne an individual LPAR capacity
limit.
The z10 EC has fi ve models with a total of 100 capacity
settings available as new build systems and as upgrades
from the z9 EC and z990.
The fi ve z10 EC models are designed with a multi-book
system structure that provides up to 64 Processor Units
(PUs) that can be characterized as either Central Proces-
sors (CPs), IFLs, ICFs, zAAPs or zIIPs.
Some of the signifi cant enhancements in the z10 EC that
help bring improved performance, availability and function
to the platform have been identifi ed. The following sections
highlight the functions and features of the z10 EC.
