By Kwok Kong, PMC-Sierra

I am pleased to announce the 1.3 release of the open source Open Fabrics Alliance (OFA) NVM Express Windows driver. This release is a result of an excellent collaboration between the NVM Express communities.

The following major features have been added to this release:

  • Hibernation
  • NUMA group support
  • CPU-MSI vector and queue map learning enhancement
  • Logical CPU core enumeration enhancement
  • 32-bit driver support for Windows 7 and 8 • Reset handling enhancement
  • SRB extension support
  • Several bug fixes

Release 1.3 is now behind us and we plan to make the next 1.4 release in late 2014. The focus for 1.4 release is stability and passing the Windows Hardware Certification Kit (HCK) in order to be digitally-signed by WHQL.
