SAN Setup

This may be a stupid question, but I figured I would throw it out there and see what you all think. I have a HP 2324fc SAN array with two controllers. It has 24 146GB 10k drives in it. I currently have two HP Proliant G4 servers going through a fibre channel switch to the array. My question is for the setup of the drives. Should I make it one big vdisk running RAID10 with two spares or break it up in half 10 drives each running RAID10 with two global spares? If I were to break it up I could put one set on one controller and the other set on the other controller.

Any thoughts?

Thanks,

See

I suggest to create two different group (one for RAID10 and one for RAID5), and then create some LUNs on each group.

Just curious to why one Raid10 and one Raid 5. Sorry I'm new to the SAN world.

You have a lot of disk so probably you do not have space problem.

So RAID10 (the best solution from performance and availability) could be the right solution.

But I think that space is never enough, so you can create a second RAID5 group for workload that do not neet big I/O write performance, but can need more spaces.
