Supporting EV7-based Alpha systems and delivering enhanced performance, availability and serviceability to Tru64 UNIX users across the AlphaServer systems family

Continuing to deliver as published in our roadmap for Tru64 UNIX, HP is now shipping Tru64 UNIX and TruCluster Server software V5.1B-2, the second minor update to Tru64 UNIX Version 5.1B.

HP recommends upgrading Tru64 UNIX systems to the latest version Tru64 UNIX V5.1B-2 for the longest, lowest-cost support and optimal performance and functionality, and clustering where you have 2 or more systems for lower system management costs with higher availability.

It remains true that vast majority of independent software vendors (ISVs) have committed to continue support for existing applications on Tru64 UNIX Version 5.1B and its updates. In fact, over 80% of the key commercial application providers have committed to release their latest version on Tru64 UNIX in 2004.

Tru64 UNIX V5.1B-2 delivers complete binary compatibility with existing Tru64 UNIX Version 5.1 applications, with no need for software recertification.

What’s New in Tru64 UNIX V5.1B-2

Tru64 UNIX V5.1B-2 delivers enhancements which improve system and cluster performance, availability and serviceability. Here are the key new features in Tru64 UNIX V5.1B-2, grouped by their benefit to your environment:

Inclusive patch kits

The 5.1B-2/PK4 kit marks a new way of delivering Tru64 UNIX fixes. In it we have introduced the concept of an all or nothing installation. This optimization radically reduces the amount of time required to install a Patch kit.

Faster boot times with clustered logical storage manager (CLSM)

With this new code optimization, member nodes in a cluster boot up to 60% faster than before, as was the experience of a key Tru64 UNIX customer in their high-performance technical computing environment. Individual customer results will vary, depending on the size and number of active members in the cluster.

Improved Memory Channel performance during peak system utilization

The Memory Channel Subsystem has been enhanced to support parallel Memory Channel input processing, which increases peak performance, and ensures more continuous data supply to CPUs. During peak system utilization, the enhanced concurrency produces increased resource availability, via additional input threads working in parallel. Parallel Memory Channel input improves performance during peak demands, with no performance degradation during normal system utilization.

Unified buffer cache scaling

With Version 5.1B-2 we introduce Unified Buffer Cache Scaling, which greatly improves large SMP and NUMA system performance.

Because EV7-based systems are PCI-X systems with MSI-capable devices and drivers, customers will see better performance from reduced locks, especially in large configurations.

Improved cluster efficiency for bad disk detection and handling

Improved cluster efficiency for bad disk detection and handling mitigates the risk of unplanned downtime and reduces the system overhead to run this self-healing feature on your Tru64 UNIX V5.1B-2 systems. Now, bad devices are identified and handled nearly twice as fast.

Worldwide language support enhancements

With V5.1B-2 we have taken the opportunity to update the various localized messages. We have also improved the over all performance of the Asian TTY subsystem under heavy loads. In addition we have enhanced support of Chinese characters together with improved iconv converters for Japanese mainframe codesets.

Networking improvements

V5.1B-2 updates support of Mobile IPv6 to the latest Networking RFCs. In addition the IPv6 Advanced API now conforms to RFC 3542.

Associated products

With V5.1B-2 we have bundled in many updated versions to the various applications which we refer to as Associated Products. These applications have been identified as having a close affinity with the Tru64 UNIX operating system and are thus widely used among our user base. The following applications have all been updated as of V5.1B-2:

  • Advanced Server for UNIX
  • TruCluster Server
  • Worldwide Language Support
  • LDAP Client Utilities
  • OpenLDAP
  • DataDirect (ODBC/JDBC Driver)
  • Mozilla
  • Worldwide Language Support
  • Tru64 UNIX to HP-UX Software Transition Kit
  • Perl
  • CollguiExtended System V Legato Networker
  • Motif 2.1 Secure Web Server
  • UniCensus check
  • Visual Threads
  • WEBES UniCensus check
  • Visual Threads

ISV partnerships and bundled software from HP and ISVs

Tru64 UNIX has entered into an extended commitment with DataDirect Technologies to ensure that Tru64 UNIX customers will have access and support on ODBC and JDBC drivers for at least the next 6 years. This will also ensure cross-platform interoperability between various databases which may or may not reside on Tru64 UNIX.

In addition, we have also bundled into V5.1B-2 the following ISV and HP offerings:


Did you hear?

In May 2004, HP communicated important updates to Tru64 UNIX users:

  • Refreshed the Tru64 UNIX roadmap with increased detail for the next Tru64 UNIX update release, Version 5.1B-3.
  • Extended availability of Prior Version Support with Sustaining Engineering (PVS-SE) for Tru64 UNIX Versions 4.0F, 4.0G, and 5.1A.
  • Announced that HP-UX 11i v2 now supports the HP StorageWorks MA8000, EMA12000 and EMA16000 HSG80-based fiber channel controllers.
