I am prepping a new box for gamnig and work. I deal a lot with VMs (up to 8 at a time) and need a raid solution.
I am currently using a pair of Raptors in a stripe and was wondering what the performance comparison is in relation to a 6 drive, 7200 RPM disk array (I would prefer 1+0 as it is less wear and tear on the disks then a raid 5) in comparison to a single 10k raptor and a pair of 10k raptors in a stripe.
Two big stickie points is the number of IO operations as with 8 VMs running there can be a sick amount of IO going on with nothing really happening. As I am a broke SOB I can really pop for a nice raid controller so this is strickly via an onboard solution (soft raid in other words).
Anyone have 6 7200 rpm drives and a pair of 10k raptors want to do some benchmarking? Big focus on IO and latency as with soft raid data has to go to the cpu and back so IO operations should have a more signifcant hit on the system then via a controller card...
If the performance hit is too bad then I might be able to win the argument and get a decent raid controller.
Please help I need hard numbers to win this.
(On a side note dear TH crew: Please do a Virtualzation special on running 4-8 concurrent VMs with various configs to find out the most optimal solution for hosting VMs, compare opterons, xeons along with desktop processors and see if the server cpus afford better performance in VM hosting)
