As we know, ZFS works faster on multiple devices pool than single device pool.
However, the above statement is it only apply to local disk? how abt SAN?
SAN as we know if we allocate (for example) 100GB, this 100GB may makes up by 3 to 4 hard disk on SAN level and present it to Solaris as 1 devices (LUN).
So according to the "ZFS works faster on multiple devices pool than single device pool", is it better to create 5 Luns (each for 20GB), then we create a zpool based on 5 Luns to have 100GB?
