Hi there.
Well, pretty tough question here...
On many arrays, the disk chunk size is 64K by default. I was told a long time ago by a storage expert on Clariion arrays that it is better to use 256K or 512K stripe size, meaning for example with RAID5, 4+1 or 8+1 disks, or RAID6, 4+2 respectively 8+2.
This makes sense as long as the array is taking advantage of that, but I don't really understand if this is a standard issue for any array, or if it is manufacturer based.
If any expert around here has a theory for, or against this, I would be grateful.
