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PRF features have been withdrawn from z/VM V5.1.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.
