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.
