Change history

Version 2.2.3-101583

Severity:

  • Added Adapters Noted Below Only: 100 - New Function Only/No fixes
  • Legacy Only Adapters: 40 - Moderate Impact/Low Probability of Occurrence
  • Mixed Legacy and Added Adapters: 10 - High Impact/High Probability of Occurrence

Enhancements:

Added Support for:

  • 320 GB High IOPS SLC Adapter for IBM System x (81Y4535)
  • 640 GB High IOPS MLC Adapter for IBM System x (81Y4531)
  • 640 GB High IOPS SLC Duo Adapter for IBM System x (81Y4539)
  • 1.28 TB High IOPS MLC Duo Adapter for IBM System x (81Y4527)

New Features:

  • Improved continuous write performance
  • Decreased memory utilization
  • Reduced groomer induced latency spikes (not an issue for most workloads)
  • Improved write endurance for all products.
  • Thermal monitoring and preemptive performance throttling / shutdown in over temp conditions to prevent thermal damage to IBM High IOPS SSD PCIe Adapters. See the user guides for further details.
  • 4k sector sizes, along with existing 512b sectors on most platforms.
  • Support for hosting a page file/ swap partition.
  • Parallel attach on driver load when auto_attach enabled (default), most platforms.
  • Parallel scan of all drives after a dirty shutdown.
  • Trim/Discard enabled by default.
  • Fine tuning options for preallocate mode.

Management/Utilities:

  • Driver and other configuration file name changes to iomemory-vsl and VSL.
  • fio-attach and fio-detach can take multiple /dev/fct* devices simultaneously.
  • New fio-format options and capabilities:
    • Don't prompt, was -f in 1.2.x, is now -y in 2.x.x.
    • Run quietly, -q.
  • fio-status
    • Added RAM usage statistics
    • Reports power related metrics.
    • Added PCIe width and other PCI related items.
  • Linux: Improved fio-status speed when driver loaded.
  • fio-status no longer displays 'unknown' if slot number is invalid, doesn't display the 'slot:' tag at all.

Fixes:

  • Fixed calculation in media health percentage.
  • Improvements in shutdown handling.
  • Work on systems with IOMMUs.
  • Fixed fio-status induced lockup.
