Its probably cheaper but if you have the money and like cool looking
machines running tons of light in your cold room then its fine :)

Subject: clustering
Just something I've been thinking about:
Assume 20,000 users. Ignoring storage needs for a moment:
8 boxes of Datacenter give you 2 x 4-node clusters, 6 active, 2 passive,
hosting roughly 3334 users each. (25% hot standby)
8 boxes of Advanced Server give you 4 x 2-node clusters, 4 active, 4
passive, hosting 5000 users each. (50% hot standby)
To achieve the same user load figures on AS as for Datacenter you need an
extra 4 boxes, a total of 12.
I wonder how the cost of 4 extra boxes compares to the Datacenter support
costs??
