Hi, HL ProLiant DL380, dual Xeon 120 GB RAID L1 for system 2 TB RAID L10 for VM disks 5 VMs, 3 Linux, 2 Windows Total CPU load most of the time is low, high level of activity related to disk. Host engine under KVM appliance on SuSE, can be easily moved, backed up, copied, experimented with, etc.
You'll have to use servers with more RAM and storage than main. More then one NIC required if some of your VMs are on different subnets, e.g. 1 in internal zone and 2nd on DMZ. For your setup 10 GB NICs + L3 Switch for ovirtmgmt. BTW, I would suggest to have several separate hardware RAIDs unless you have SSD, otherwise limit of the disk system I/O will be a bottleneck. Consider SSD L1 RAID for heavy-loaded databases. *Please note many cheap SSDs do NOT work reliably with SAS controllers even in SATA mode*. For example, I supposed to use 2 x WD Green SSD configures as RAID L1 for OS. It was possible to install system, yet under heavy load simulated with iozone disk system freeze, rendering OS unbootable. Same crash was experienced with 512GB KingFast SSD connected to broadcom/AMCC SAS RAID Card.
