Guidence creating / breaking up disk pools on EMC AX4-5 SAN

Hi All,

I've done some research but I can't seem to find the information I am looking for and decided to utilize this forum to perhaps get some guidance on my issue. Let me break down some specifics for you all

We have:

EMC Clariion AX4-5 SAN with two storage processors
Two Disk Pools, one holding VMWare data and one holding Sharepoint data

The Disk Pool I am looking to review is the one containing VMWare information. This Disk Pool currently houses 13 400GB Hard drives (Totaling 4.65TB of data) spanning a RAID 5 Array.

Does anyone know if there are any guidelines as far as how large a Disk Pool should grow before creating a new disk pool (Rather than expanding to add more drives).

Data throughput is a concern since at some point the RAID 5 array becomes inefficient not to mention the time it takes to expand an array that size is significant. Is there any way to measure the amount of throughput to find out at what point the number of drives becomes a bottleneck to the system?

I have also been tasked with breaking up the current disk pool but I will likely work with EMC get this done. Any tips in this venture are also appreciated.

Looks like we are going to break this up a few different ways but it will be a project to figure out how we are going to do that. I appreciate the guidance and yes the risk of having two drives go is higher with that many drives and needs to be addressed. It may be a few months before we deploy a solution on this (many different parties are affected and we need a project plan in place) but if I remember I will come back and post our solution and breakdown.
