A customer has an application with a large sequential I/O pattern and wants to design the storage for the best possible performance.
Which design solution would you recommend?
A.
Create one LUN per RAID group; present them to the host and use a Volume Manager to stripe across them.
B.
Create one LUN per RAID group; create a striped metaLUN across all LUNs and present the metaLUN to the host.
C.
Create multiple LUNs per RAID group; present them to the host and use a Volume Manager to stripe across them.
D.
Create multiple LUNs per RAID group; create a striped metaLUN across all LUNs and present the metaLUN to the host.
“B” is better.
