EMC best practices, different RAIDs in the same pool?
Hi,
What happend when we have applications that are best suited to RAID 5 and others than work better with RAID 1/0, we create two different pools? or we combined in a pool two different RAID?
Thank you!

You can only have one RAID type per tier in a pool. For example, you can't have a pool with some SAS disks in R5 and other SAS disks in R1/0. You could have EFD in R5 and SAS in R5 or 1/0 though. (as an example)
So if you have workloads that you would prefer to have different RAID types (but using the same type of disks), you'd need to have multiple pools or you could have a mix of Pools and traditional Raid Groups.
The docs Dynamox has linked are 'gold' for this type of info.
