Hello, what do you think a server with Intel® Core™ i7-980X , 24GB ram, 4x1.5TB HDD in h/w RAID10 ? I`m afraid most of the CPU is it good for runing Virtual servers on it?!
I want to use for VPS node.
And what do you think what platform should i course ?! OpenVZ, Xen or KVM ?!
Planning to run SolusVM on it. Any need recommendations on this part too.
From what I can tell, solusvm works better with openvz than with xen, so if you're going with solus, openvz is probably a good choice.
As to the cpu, we've not even scratched the surface of the cpu available to us, using nodes with slightly less processing power, and 16gb ram, so I think you'll be fine with that cpu and 24gb ram. All our VMs start at 1gb ram and up, so if you're allowing VPS's with 256mb ram, the cpu to ram ratio might require more cpu for you than it does for us. Even so, I would think you'll be ok on the CPU side of things everything considered.
As to the hard drives, to make sure you get good performance, make sure the raid stripe is 1MB or larger, as the smaller stripe sizes that are common defaults will cause unnecessary i/o usage across multiple drives for requests that should only need to access one drive. If you can increase your linux readahead to 1/4 of the stripe size, this will also improve performance. Typically the readahead if 128K, so if you have a 1M stripe, you should increase this to 256K. If your h/w raid card allows a 2M stripe, go with that and a 512K readahead for the best performance.
