The Integrity VM V4.0 release introduces new 11i v3 accelerated storage and networking products to improve the overall I/O performance for Integrity VM. Accelerated Virtual I/O (AVIO) products provide up to a 60% reduction in service demand and as much as twofold improvement in throughput over the existing fully virtualized storage and networking Integrity VM solutions. Performance depends on the application workload and, in general, is better with larger message sizes.

The following list describes enhancements to Integrity VM for this release:

  • Support for HP-UX 11i v3 as a VM Host – including features of HP-UX 11i v3, such as long user names, host names, and PIDs

  • Guests can run any of the following operating systems:

    • HP-UX 11i v2 (0609 or later)

    • HP-UX 11i v3 — 0703, 0709, 0803, and 0809

    • Windows 2003 (Enterprise or Datacenter edition) SP2

    • Red Hat Linux Enterprise Edition Advanced Server Release 4 update 5

    • SUSE Linux Enterprise Server (SLES) for HP Integrity servers SLES 10 update 1

  • AVIO supports the following new features:

    • HP-UX 11i v3 guests

    • File backing stores for 11i v2 and 11i v3 guests

    • Asynchronous event support for better guest manageability

    • Performance scaling for multi vCPU configurations

  • HP SIM/VMAN — Facilitates the display and management of Integrity VM MSE server groups. An API is supported to set and get the name of the MSE server group.

  • 8 vCPUs — Increases scalability of Integrity VM to 8 virtual CPUs, which allows running guests with up to 8 vCPUs to be configured. .

  • Proximity support — New hardware division in cells. Cells are divided into two or more Front Side Buses (FSBs), called a proximity. Threads on the same FSB/proximity have better performance for in-cache locking than those on separate FSBs. When Integrity VM detects this hardware feature, the scheduler must place multi-CPU guests on the same FSB.

  • Disk management and CLI improvements.

  • Performance measurements improvements — Addition of the hpvmsar utility to measure performance.

  • APIs for management of Integrity VM Server groups and distributed guests.

  • Legacy and agile device-naming support — Add agile device-naming support provided by HP-UX 11i v3.

  • Automatic cell balancing — When the host is predominantly cell local memory, or the guest has the sched_preference flag set to “cell”, Integrity VM automatically pick the best fitting locality domain for the new guest. For applications that may perform better with interleaved memory (such as a massively-threaded Java™ configuration), you can override cell selection by specifying ilm.

  • Large page (64K) support on host — Provides support for 11i v3 larger base-page sizes.

  • IPv6 support on HP-UX 11i v2 and 11i v3 guests and HP-UX 11i v3 VM Host— Provides IPv6 support in Integrity VM Version 4.0.

  • Per-guest capping functionality — Provides support for a new type of capping that allows you to set a limit on how much of a CPU a virtual machine can use.

  • OL* AddOnHost — Provides OL* handlers to Integrity VM such that when a cell is added, both the processors and the memory in the cell are added and become available to the host.

  • Concurrent dump — Allows an HP-UX crash dump to be captured on multiple I/O devices using simultaneously occurring I/O operations in parallel on all the configured dump devices.
