I've got a new Dell PowerEdge 710 w/ two 146GB 15k SAS drives in a RAID1 for the OS. I have a second array of four 300GB 15k SAS drives in a RAID10. In looking up best practices for configuring disks, all the sites seem to assume I have as many disks as I can imagine at my disposal. None offer any advice where I've got two RAID arrays to play w/. Any suggestions?
I'm thinking I've got my OS array (C:) and I'll keep transaction logs there and put the database on the second array (E:).
My question, do I gain anything by partitioning out the OS RAID1 array and/or the larger RAID10 array?
I've seen a few hints suggesting to partition out the smaller RAID1 array and put the OS on a 40GB partition there and then the logs on a 100GB partition, but this doesn't make sense to me. If the array is partitioned, it's still using the same physical disks so where is the performance improvement?
