IBM® PowerVM® 3.1.2

IBM PowerVM 3.1.2, which delivers industrial-strength enterprise virtualization for IBM AIX®, IBM i, and Linux® environments on IBM POWER® processor-based systems, has been enhanced with additional capabilities including optimized Live Partition Mobility (LPM).

PowerVM VIOS 3.1.2 offers:

  • NPIV acceleration: VIOS has enhanced Fibre Channel NPIV to provide multiqueue support. NPIV multiqueue provides improved performance, including more throughput, reduced latency, and higher IOPS, by spreading the I/O workload across multiple work queues.

    Note: In addition to VIOS 3.1.2, the following requisites are required for the full performance benefits of NPIV multiqueue support:

    • 16 GB or 32 GB Fibre Channel adapter - Feature codes EN1A, EN1B, EN1C, EN1D, EN2A, and EN2B.
    • AIX 7.2 technology level 5, or later.
    • Power® 9 systems with FW940, or later.
  • Fibre Channel Congestion Control (NPIV): SAN switch status gets sent back to the host software, including multipathing, enabling better and faster pathing decisions.
  • VIOS Secure Boot (tamper-proof image): FW-assisted verification of the authenticity of the VIOS digitally signed boot image and boot process. This requires Hardware Management Console (HMC) 950.
  • VIOS Maintenance Tool (HMC): Validate VIOS redundancy, backup, and restore.
  • LPM support for multiple client virtual Fibre Channel (VFC) adapters (NPIVs) mapped to a single physical FC port (IBM i only).
  • SSP resiliency enhancements.

IBM NovaLink 1.0 media will be delivered electronic only.

IBM Virtual HMC (vHMC) 9.2.950

IBM vHMC 9.2.950 gives clients the ability to use their own hardware and server virtualization to host the IBM-supplied HMC virtual appliance. Additional enhancements include the following:

  • Support for additional I/O adapters
  • Platform KeyStore enablement
  • Validation of VIOS maintenance mode
  • VIOS backup and restore from HMC and store VIOS backups in HMC
  • Multithreaded support for LPM performance improvements
  • UI enhancements, including DLPAR add/remove adapter for vSCSI/vFC in VIOS or client VMs
  • Transport protocol TLSv1.1 support removed from all HMC communication channels
  • DSA key authentication disabled

The following cipher protocols are disabled in all crypto policy levels:

  • DH with parameters < 1024 bits
  • DH with parameters < 1024 bits
  • RSA with key size < 1024 bits
  • RSA with key size < 1024 bits
  • Camellia
  • ARIA
  • SEED
  • IDEA
  • Integrity-only cipher suites
  • TLS CBC mode cipher suites using SHA-384 HMAC
  • AES-CC

IBM Cloud® Management Console

  • IBM Cloud Management Console (CMC) support for dedicated processor VMs in IBM Power Enterprise Pools 2.0.
  • IBM Power Private Cloud Solution and Enterprise Pools 2.0 supports up to 1,500 virtual machines and up to 48 systems in a pool managed by a single CMC, with up to 500 virtual machines supported per HMC.
