improved management, performance and availabililty

Tru64 UNIX and TruCluster Server software Version 5.1B delivers support for AlphaServer systems including EV7-based systems up through 32 processors. This major release of the operating environment also provides enhancements to increase performance and availability, as well as increase ease-of-management for Tru64 UNIX in single systems and in clusters, with enhancements to the industry-leading TruCluster Server software.

Version 5.1B-1 is required for 64-processor GS1280 and DS15 systems: that update release further improves key features of the operating environment. HP recommends remaining current with updates and patch kits of its operating systems for best performance and most economical support.

When should customers move to Tru64 UNIX V5.1B?
Customers purchasing Tru64 UNIX with their EV7-based AlphaServer systems will receive Version 5.1B. Customers clustering an EV7-based AlphaServer system with existing AlphaServer systems will need to upgrade all other members of the cluster to Tru64 UNIX V5.1B.

Customers running memory-intensive applications on Alpha EV6-based AlphaServer systems including databases should consider upgrading for performance increases. Applications that currently run on Version 5 of Tru64 UNIX require no changes or recompilation to run on version 5.1B.

HP has extended the duration of support for some prior versions of Tru64 UNIX. Tru64 UNIX V5.1B is the version HP will support for the long-term.

Performance boosts with no changes required: scaling for power
Tru64 UNIX V5.1B allows customers to scale up to 32 processors and 256 GB of memory. Its support for EV7-based systems’ big memory pages results in faster applications, particularly database applications. Both in single systems and clusters, Tru64 UNIX continues to excel in Oracle9i database performance: ask your sales rep for performance data.

Expanding availability and resiliency, securely
For maximum system and application availability, Tru64 UNIX V5.1B detects CPU component failures and takes them off line, allowing customers to take action on their schedule without disrupting operations. And to make things easier for our customers, we have integrated SSH into V5.1B to make security as configurable and transparent as customers need it.

Easier management, built-in flexibility
Single-system management enhancements with Tru64 UNIX V5.1B include increased flexibility in configuring networks, allowing customers to deploy their wireless connectivity infrastructure more quickly. For flexibility now, extending without limits into the future, we’re shipping both IPv4 and IPv6 internet protocol stacks with Tru64 UNIX V5.1B: customers can run both at the same time, enabling no-downside preparation for the next phase of IP addressing.

Support for EV7-based AlphaServer systems

How many processors does Tru64 UNIX V5.1B support in the new EV7-based AlphaServer systems?

By system model, here are the specifics:

  • AlphaServer ES47 - 2 or 4 processors
  • AlphaServer ES80 - 2, 4, 6 or 8 processors
  • AlphaServer GS1280 - 2, 4, 6, 8, 16, or 32 processors

performance: Support for the EV7-based AlphaServer systems’ big memory pages accelerates memory intensive applications as commonly found with database applications and in the HPTC market.

  • The popular SSH secure shell utilities are now bundled with the OS, bringing the quality assurance and ongoing support appropriate for commercial UNIX deployment.
  • Security hardening and ease of use enhancements.
  • Pseudo random number generation.
  • Directory enabled authentication via LDAP.
  • Common Data Security Architecture (CDSA) and IPsec now integrated with the OS.
  • Logical Storage Manager (LSM) will now support fast plex re-attach by writing on the reattached device only the parts that have been changed (in its mirror) since its detachment, not the entire image of the device. This results in significant performance increases.
  • Support for Enterprise Volume Manager (EVM) V2.0 provides the framework to do software snapshots and cloning. With this functionality, system administrators do not need to take their application environment offline during the creation of a snapshot/clone, but they can still maintain data integrity. AdvFS provides Freeze/Thaw support to enable consistent clone or snapshot operations.
  • Support for Enterprise and VersaStor provides storage virtualization across a SAN and expansion of storage volumes.
  • AdvFS is enhanced to provide selectable background automatic disk defragmentation using the Vfast feature.

IPv6 networking
  • Tru64 UNIX V5.1B ships both IPv4 and IPv6 stacks, which can both run simultaneously, to continue your current network configuration while preparing for future expansion.
  • Mobile IP support provides a home agent to enable Tru64 UNIX to be a server for mobile nodes. In addition, support for mobile laptops enables forwarding traffic from the home agent to mobile laptops.
  • Wireless connectivity: A home agent provides server functionality to enable wireless devices to be serviced by a Tru64 UNIX server. This expands the concept of the network from a wired network to also include wireless connectivity.
Availability (with TruCluster Server V5.1B)
  • CPU and certain PCI card indictment: Tru64 UNIX V5.1B serviceability features allow the system to automatically detect failing CPU and certain PCI boards, to avoid system crashes. Specifically regarding PCI cards, as of Tru64 UNIX Version 5.1B, one can indict the KGPSA PCI Adapter card on the EV7-based AlphaServer systems as well as the GS80, GS160, GS320, ES45 and DS25 systems. Customers can, therefore, experience maximum system availability until they are ready to service these components at their most convenient time.
  • Memory troller: The memory troller pro-actively locates and scrubs correctable memory errors prior to the operating system or application reading the memory. It maps bad pages out so they will not be reused, preserving high system and data availability.
  • CFS load balancing infrastructure: Balances the file system load across multiple nodes
  • CFS mount affinity: Mount and serve specific file systems providing flexibility for large NFS client installations
  • Automatic fail-back based on time of day
  • Faster software upgrades

Other new features
  • Reduced boot time for the AlphaServer GS series systems
  • Support for 48 new printers
  • Printing management via SysMan
  • Support for latest Unicode standard
  • Support for latest Java and Java FastVM version
  • System management and serviceability enhancements
