Purpose
This article details the EMC CX and VNX firmware and vSphere requirements for vSphere VAAI Block Hardware Acceleration Support on vSphere 4.1 and 5.x.
Resolution
See this brief matrix of current VAAI support for EMC CLARiiON and VNX arrays:vSphere 4.1vSphere 5.xCX4 Series Flare 30/29/28+VAAI SupportedVAAI Not SupportedVNX Series OE 31 or Later *VAAI SupportedVAAI Supported* For more information on VNX series firmware, see Minimum firmware requirements for EMC VNX Series arrays for vSphere VAAI block support (2006239).VMware VAAI Support through VMware VAAI Certification must meet performance criteria. Failure to meet performance criteria will result in not supporting the VAAI feature. However, a partner vendor may choose to support VAAI without any performance criteria met.
