Expanding a Storage Pool - good practices
Hi
I have been tasked with increasing a Clariion Cx4 Storage Pool could anyone answer the following questions:
- Is the process disruptive?
- What are the performance implications of expanding a storage pool?
- Any good practices that I should comply with?
Thanks

Hi Grearoid,
Just want to confirm something. If I have a 40 drive R5 pool, and I expand it with another 40 drives, won't I get the same performance that I used to get before the expansion. The rule-of-thumb is to expand the pool with the same number of drives that you used to create the pool initially.

Once again the important question is
What code is the array running
Without that information I cannot give you a definate answer
If release 32 then the performance will be the same or better
If older code then the performance maybe the same or worse
