Which VAAI command in latest VPLEX ?
Hello,
It's not clear for me which VAAI commands are support by the latest VPLEX Metro (5.2. SP1 P1).
WriteSame is mentionned for release 5.2.P1 https://support.emc.com/docu48041_VPLEX_with_GeoSynchrony_5.2_Patch_1_Release_Notes.pdf?language=en_US
ATS (or CAW) in 5.1 :https://support.emc.com/docu40034_VPLEX_GeoSynchrony_Release_5.1_and_Patches_Release_Notes.pdf?language=en_US
But what about XCOPY?
If we use 1-1 devices in the VPLEX and the storage backaned array (ex VNX) supports all the VAAI commands, will VPLEX just pass-on the VAAI commands?
Thanks,
Francis

Right now only WRITE SAME and ATS are supported. XCOPY and UNMAP are not. WRITE SAME is passed through to the backend array if possible. I am not entirely sure about ATS though.

Thanks for the quick reply! I suppose this is not the place to ask when XCOPY will be supported.

Sure thing! Yeah--something for your EMC rep to ask VPLEX Product Mgmt about.

ATS has been supported since GeoSynchrony 5.1.
WriteSame has been supported since GeoSynchrony 5.2.
XCOPY is planned for GeoSynchrony 5.3.
