We are sticking to rack servers at the moment. We don't have the server sprawl or the processing requirements to fully utilize a full blade chassis, so blades aren't cost effective for our current environment.
We also we rack servers (Dell 905Rs to be specific). This gives us a couple of big servers that house all our VMs. We went with 2 large servers instead of a bunch of smaller servers (or blades) as we needed a lot of NICs for all our vLANs and to save on HBA and vSphere licenses costs.
While deciding blades vs. rack for virtualization project also consider the following:
- supporting infrastructure (KVMs/Switches/UPS/NAS or SAN)
- available resources (number of RAM/HDD/CPU sockets) and desired utilization level
- available floor space, air conditioning and power density
- maintenance and availability
