Description
Create a VD that can be accelerated using the DAS Cache
utility:
perccli64.exe /c0 add vd type=raid0
drives=<EID>:<Slt> direct wt ra pdcache=off
Example:
perccli64.exe /c0 add vd type=raid0 drives=32:6
direct wt ra pdcache=off
Create a VD that can be accelerated using a utility such as
RFcache, or that will not be accelerated at all:
perccli64.exe /c0 add vd type=raid0 drives=32:6
direct wt ra pdcache=off
perccli64.exe /c0 add vd type=raid0
drives=<EID>:<Slt> direct wb ra pdcache=off
Example:
perccli64.exe /c0 add vd type=raid0 drives=32:6
direct wb ra pdcache=off
