We are thinking of building our own hypervisor hardware (in high volumes) for our virtualized hosting platform, instead of buying from Dell. Our model is small virtual machines 256MB of memory, and 10-15GB of disk. So, its a lot of small virtual machines (55-60) per hypervisor.
Looking for recommendations, comments, and part numbers. We want to start with a super-micro chasis, and then get a motherboard, cpu, memory, NICs, and disks.
Any recommendations on the best 1u super-micro chassis model to use? Motherboard (prefer AMD), memory, disks, NICS, power supply?
Thinking 12 cores (2) 6 core AMD cpus, 16GB of memory. Would be nice to do 32GB of memory, and fit more virtual machines per hypervisor, but I think the IO (storage local to hypervisor) is really going to be the bottleneck, so no use in putting more memory. Disks (4), 15K rpm, SAS, 500GB in RAID 10. Need (2) gigabit ports, can be embedded on the motherboard, unless there is a real benefit to splurging on Intel NICs.
