So I've been playing around with storage options on my home server and there seems to be a bottleneck with write performance on the server that I can't pinpoint.
The server is a HP ML350 G5, using the built in Smart Array e200i raid controller. All drives are 2TB 7.2k SATA3. I've tested a variety of things and here are the results:
Test 1 - 4 drives in raid 1+0 using built controller
Test 2 - 4 drives using Windows Storage Spaces Simple Array
Test 3 - 4 Drives usings Windows Storage Spaces Mirror Array
Test 4 - 4 Drives using Windows Storage Spaces. 2 mirrors created and then data striped across the mirror using disk management (Fake Raid 10)
Now from the test results, its clear each differing setup is making a difference to the Read results, but the Write results are just consistently poor.
I'm unsure at this point would could be causing this issues, although I'm leaning towards it being the e200i controller just being poop. Anyone have any ideas what else I could try to do to improve this performance ?
