Hello ettringite99

I don't see any issues with it. With the 16 drive configuration you will be full populating it. The controller will support all of the RAID levels and the number of arrays you are wanting to create.

I would recommend that you go with a PERC H710 rather than the H310. The performance and caching capability of the H710 versus the H310 would be quite noticeable using this many drives. If there will not be a lot of drive utilization then the H310 will be fine.

Thanks

[Edited to correct controller models to PERC 8 rather than PERC 7]

Dan,

I'll be using the H310, not H200. Can you see any problems with this?

That was a typo on my part. I meant to type H310. The H200 would not support the configuration.

Thanks

Cheers for the tip Dan,

I guess I'm going to have to thoroughly test this, the system will be an emergency system only, which means either none or around 3000 users will hit the server at once.

The R720 doesn't support/offer the H700, but it does have the H710 option. I'd highly recommend an H710 over an H310 if you could run into situations where you need to have 3000 users on the system.

Hi guys,

Thanks for your previous comments, just 1 other question. I've revised my storage design a little:

raid 10 using 5 x 900 GB disks - LUN 1

raid 10 using 5 x 900 GB disks - LUN 2

raid 1 using 2 x 146 GB disks - LUN 3

raid 1 using 2 x 146 GB disks - LUN 4

This leaves :

1 x 500 GB hot spare

1 x 146 GB hot spare

Is it possible with the H310 to share the hot spare across different raid sets (i.e have LUN1 & 2 be able to use hotspare 500GB) if needed?

If not, would another controller resolve this?

Unfortunately the kit has already been ordered, but I need to determine whether or not to change it? I was planning to do some bench mark testing as I need to squeeze out 700 iops - which will determine whethere I need to go back to client and them back to Dell.

Also;

raid 10 using 5 x 900 GB disks - LUN 1

raid 10 using 5 x 900 GB disks - LUN 2

Raid 10 requires an even number of drives. You'll have to recheck your intended setup (unless you meant to say raid 5).
