Benchmarking HDD performance (cross post to servers sub-forum)

post #1 of 2
Thread Starter 
So I'm getting on the virtualization bandwagon. I'm deploying a supermicro bladecenter and starting off with 1 blade (with a spare for parts). I am using Promise iSCSI for storage (it's sitting in my spare bedroom, it's sweet), and I wondered what everyones thoughts were on how to benchmark the iSCSI, and what RAID configuration I should be choosing.

I'll be using the Promise Vtrak M610i as my initial storage platform, populated with 500GB Seagate Barracuda ES.2 drives. I'm leaning towards a 14 drive RAID10 array, with two hot-spare drives. The only concern I have is that I'll end up with not enough space. 3.5TB pre-formatted capacity isn't all that much for the amount of virtualization that I will be doing.

What kind of tests can I do to check I/O throughput in RAID5 and RAID6 modes to determine if I can go with either of those RAID levels? I'd really love to have a 15 drive RAID6 array (6.5TB w/ one hot spare) if I can get away with the parity overhead calculations. I'll be running webservers off of this iSCSI box, and based on current CPU and memory usage trends, I'll be able to put somewhere between 10-16 VM's on each blade.

Any thoughts? (PS - the bladecenter should be coming in next week, the promise box is already in, the drives, CPU and memory will be here in the next day or two. I'll take pics of all of it when it's all here - 32GB of RAM should be an interesting sight to behold)
