I have a HP DL180 G6 with a P410 raid controller. Presently this runs using 4x 1TB Samsung Spinpoint SATA drives, in a RAID10 configuration using default settings. I am about to add a backplane to increase the drive capacity from 4 to 12 drives, and I plan to install 4 more 1TB SATA Drives. The drives are matched and have close serial numbers (They arrived together in the Manufacturers pallet). Model HD103UJ 1000GB/7200rpm/32M Rated for 3GB/s I will also be installing RHEL 6.1 x86_64. My question is what would be the optimal RAID settings (stripe etc.) for this configuration? To recap: 8x Model HD103UJ 1000GB/7200rpm/32M Rated for 3GB/s RAID 10 configuration. Thanks in advance. Update for role: Server is to become an iscsi target for an internal openstack deployment currently underway. (Glance) Will also provide virtualisation through KVM
