Notice Regarding Specialty Engines (e.g., zIIPs, zAAPs andIFLs):

Any information contained in this document regarding Specialty Engines ("SEs") and SEeligible workloads provides only general descriptions of the types and portions of workloadsthat are eligible for execution on Specialty Engines (e.g., zIIPs, zAAPs, and IFLs). IBMauthorizes customers to use IBM SE only to execute the processing of Eligible Workloads ofspecific Programs expressly authorized by IBM as specified in the “Authorized Use Table forIBM Machines” provided atwww.ibm.com/systems/support/machine_warranties/machine_code/aut.html (“AUT”).

No other workload processing is authorized for execution on an SE.

z/VM Version 6 Release 3Large Memory Support

Real memory limit raised from 256 GB to 1 TB

– Proportionately increases total virtual memory based on tolerable over-commitment levels and workload dependencies

– Removes reorder completely

– Virtual machine memory limit remains unchanged at 1 TB


– Virtual machine memory limit remains unchanged at 1 TB

– Paging DASD utilization and requirements change

– Improves ability to reserve storage for users and segments

Expanded storage continues to be supported with a limit of 128 GB

– But our runs show it is better to spend that storage on central


z/VM Version 6 Release 3HiperDispatch

Improved processor efficiency

– Better n-way curves

• Supported processor limit of 32 remains unchanged

– Better use of processor cache to take advantage of cache-rich system designof more recent machines


of more recent machines

Two components:

– Dispatching affinity

– Vertical CPU management

z/VM Version 6 Release 3xCAT to be shipped and installed with z/VM xCAT Extreme Cloud Administration Toolkit

Allows for Provisioning

Function added to xCAT that will be ready for z/VM 6.3

– Capture – ability to capture a virtual machine into an image that can bedeployed at a later time.

– Deploy – ability to deploy an image from previously captured image data.


– Deploy – ability to deploy an image from previously captured image data.

– Export – ability to export an image from a local repository for retention ortransmission elsewhere.

– Import – ability to import an image (possibly created elsewhere) into thelocal image repository.

– Delete Image – ability to remove an image from a local image repository.

– List – ability to discover images in a local image repository and informationabout the images. This is of primary use to xCAT.

SMAPI xCAT Open Stack IBM Tivoli Products


z/VM Version 6 Release 3Other Items

Enhanced dump – speed is improved for both ECKD and SCSI

FCP data router – lets guest exploit “DMA” capability in FCP card

Improvements in exploiting DS 8000, especially in PPRC unit checks

LGR can move a guest that uses a port-based VSWITCH

Support for OSA-Express5S devices

Improvements in VSWITCH recovery and stall prevention


Guest exploitation of Crypto Express4S

SSL server upgrade to z/OS 1.13 equivalency

Linux dump can now include the NSS

z/VM 6.3 cannot be managed by Unified Resource Manager (see SOD)

We intend to have z/VM 6.3 evaluated wrt EAL 4+ and FIPS CMVP (see SOD)

z/VM 6.3 is the last XSTORE release (see SOD)

z/VM 5.4 customers: zEC12 and zBC12 are your last processors (see SOD)

With z/VM 6.3 we want our customers to know that theyare the focus of the release

• z/VM 6.3 continues the investment into virtualization onSystem z such that it allows customers to easily deployadditional virtual server workload on System z.

Key Takeaways


additional virtual server workload on System z.

• Efficiency is a key attribute of the release. Memoryscalability to 1 TB and HiperDispatch to use our CPUsmore effectively

• Consumability or ease of system use continues to be avery important aspect as we look to an open standardsinterface and to an enhanced GUI for systemmanagement
