IBM Z10 BC manual

Additionally, several service enhancements have also been designed to avoid unscheduled outages and include continued focus on fi rmware quality, reduced chip count on Single Chip Module (SCM) and memory subsystem improvements. In the area of scheduled outage enhance- ments include redundant 100Mb Ethernet service network with VLAN, rebalance of PSIFB and I/O fanouts, and single processor core sparing and checkstop. Exclusive to the System z10 is the ability to hot swap ICB-4 and Infi niBand hub cards.

Enterprises with IBM System z9 BC and IBM z890 may upgrade to any z10 Business Class model. Model upgrades within the z10 BC are concurrent. If you desire a consolidation platform for your mainframe and Linux capable applications, you can add capacity and even expand your current application workloads in a cost-effec- tive manner. If your traditional and new applications are growing, you may fi nd the z10 BC 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 BC software pricing strategies.

The z10 BC 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 BC is designed to further extend and integrate key platform characteristics such as dynamic fl exible partitioning and resource management in

mixed and unpredictable workload environments, provid- ing scalability, high availability and Qualities of Service (QoS) to emerging applications such as WebSphere, Java and Linux.

With the logical partition (LPAR) group capacity limit on z10 BC, z10 EC, 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 BC has one model with a total of 130 capacity settings available as new build systems and as upgrades from the z9 BC and z890.

The z10 BC model is designed with a Central Processor Complex (CPC) drawer with Single Chip Modules (SCM) that provides up to 10 Processor Units (PUs) that can

be characterized as either Central Processors (CPs), IFLs, ICFs, zAAPs or zIIPs.

Some of the signifi cant enhancements in the z10 BC 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 BC.
