Technology Exploitation

•z/VM 5.1 supports the z890 and the z990 including:

–Four Logical Channel SubSystems (LCSSs) on the z990 and two on the z890

–Transparent sharing of internal and external channel types across LCSSs

–Open Systems Adapter-Express Integrated Console Controller (OSA-ICC) function

–Crypto Express2 for z/OS and Linux guests

–OSA-Express2 Gigabit Ethernet (GbE) and 10 GbE

–FICON Express2 requires PTF for HCM/HCD APAR VM63610

–FCP LUN Access Control for added control of SCSI devices and is supported by z/VM V5.1 on the z990 and z890 with the PTF for APAR VM63328.

–Up to 24 real processor engines in a single z/VM image on a z990 satisfi es the Statement of Direction made on May 13, 2003.

•IPv6 support for guest LANs has been enhanced to allow the z/VM TCP/IP stack to be confi gured for IPv6 networks connected through an OSA-Express and OSA- Express2 operating in QDIO mode. The stack can be confi gured to provide static routing of IPv6 packets and to send IPv6 Router Advertisements. In addition, sup- port is being provided to help application developers to develop socket applications for IPv6 communications.

Systems Management Improvements

The Performance Toolkit for VM has been enhanced in z/VM V5.1 to provide functional equivalence to the Perfor- mance Reporting Facility (PRF) priced, optional feature, thereby virtually eliminating the need for separate products

(PRF and RealTime Monitor (RTM)) to help manage your performance more effi ciently. Other new function includes

•High-level Linux reports based on application monitor records created by SUSE LINUX Enterprise Server 8 (SLES 8)

•New reports for SCSI disks

•Support for application monitor records created by SLES 9 with the PTF for APAR VM63580

Note: Delivery of equivalent function to PRF in the Performance Toolkit for VM satisfi es the Statement of Direction made on May 13, 2003 to remove the RTM and PRF features in a future release of z/VM. The RTM and PRF features have been withdrawn from z/VM V5.1. These features are still available with z/VM V4.4 but cannot be licensed with z/VM V5.1.

For further information see the z/VM Reference Guide, GM13-0137.
