Availability Functions

With the z10 BC, signifi cant steps have been taken in the area of server availability with a focus on reducing pre- planning requirements. Pre-planning requirements are minimized by delivering and reserving 8 GB for HSA so the maximum confi guration capabilities can be exploited. And with the introduction of the ability to seamlessly include such events as creation of LPARs, inclusion of logical subsystems, changing logical processor defi nitions in an LPAR, and the introduction of cryptography into an LPAR. Features that carry forward from previous generation pro- cessors include the ability to dynamically enable I/O, and the dynamic swapping of processor types.

Hardware System Area (HSA)

Fixed HSA of 8 GB is provided as standard with the z10 BC. The HSA has been designed to eliminate planning for HSA and makes all the memory purchased by customers available for customer use. Preplanning for HSA expansion for confi gurations will be eliminated as HCD/IOCP will, via the IOCDS process, always reserve:

•2 Logical Channel Subsystems (LCSS), pre-defi ned

•30 Logical Partitions (LPARs), pre-defi ned

•Subchannel set 0 with 63.75k devices

•Subchannel set 1 with 64K-1 devices

•Dynamic I/O Reconfi guration – always enabled by default

•Concurrent Patch – always enabled by default

•Add/Change the number of logical CP, IFL, ICF, zAAP, zIIP, processors per partition and add SAPs to the con- fi guration

•Dynamic LPAR PU assignment optimization CPs, ICFs, IFLs, zAAPs, zIIPs, SAPs

•Dynamically Add/Remove Crypto (no LPAR deactivation required)

Redundant I/O Interconnect

In the event of a failure or customer initiated action such as the replacement of an HCA/STI fanout card, the z10 BC is designed to provide access to your I/O devices through another HCA/STI to the affected I/O domains. This is exclu- sive to System z10 and System z9.

Enhanced Driver Maintenance

One of the greatest contributors to downtime during planned outages is Licensed Internal Code (LIC) updates. When properly confi gured, z10 BC is designed to permit select planned LIC updates.

A new query function has been added to validate LIC EDM requirements in advance. Enhanced programmatic internal controls have been added to help eliminate manual analy- sis by the service team of certain exception conditions.

With the z10 BC, PR/SM code has been enhanced to allow multiple EDM ‘From’ sync points. Automatic apply of EDM licensed internal change requirements is now limited to EDM and the licensed internal code changes update pro- cess.

There are several reliability, availability, and serviceability (RAS) enhancements that have been made to the HMC/SE based on the feedback from the System z9 Enhanced Driver Maintenance fi eld experience.

•Change to better handle intermittent customer network issues

•EDM performance improvements

•New EDM user interface features to allow for customer and service personnel to better plan for the EDM

•A new option to check all licensed internal code which can be executed in advance of the EDM preload or activate.
