I'm planning a VMware server on a 2U box, so fast I/O is my main concern here. My options are 6x 3.5 disks or 8x 2.5 disks. 2 disks set aside for the OS mirror, so that leaves my options for the VM partiton as the following:
Raid 10
4x 3.5" 10K rpm 146GB
6x 2.5" 10K rpm 73GB
Obviously I will take a large hit in disk space by using the 2.5" drives, but would the RAID 10 perform significantly better with 6 disks instead of 4?
I can make the 3.5s into 15k rpm as well. Is this preferable over the 6 2.5s?
Comments appreciated.
