stripe size of 64KB in RAID0
What can be a reason for a stripe size of 64KB in a RAID0 configuration?
This is what a guy give me for it's Oracle ETL process:
because I have to play with speed/performance (all discs as far as possible parallel load = small stripe size) and concurrency (disks maximum individual load = large strip size)

The default CLARiiON stripe element size is 128 blocks, which is 64 KB. The stripe element size is not configurable through Navisphere. The stripe size is the amount of user data in a RAID group stripe. It is calculated by multiplying the number of stripe disks by the stripe element size.
For example, a four-disk RAID 0 has a stripe width of four and a stripe element size of 64KB. It has a stripe size of 256KB (4 * 64 KB).
I suspect you need to discuss the CLARiiON's RAID group architecture with the requestor to clarify.
Information on stripe size can be found in the EMC CLARiiON Storage System Fundamentals for Performance and Availability, available later this month on Powerlink.

If so, could you mark the answer "Correct" so that all will know that the question was correctly answered?
Thanks,
