We are giving real thought to getting blade-servers for some of our new servers this year. Our vendor has a new generation of blade servers that seem to eliminate some of the road-blocks from previous blades. For one, they have a chassis that allows blades that use P4 CPU's. AND permit Fibre Channel connections to a SAN. The combination of all this makes it possible to have a blade be a head-unit for a SAN-based system. Such as a medium throughput, high-volume database. Or a clustered file-server. Or whatnot. On the down-side, the power requirements are a touch exotic for our existing setup, so we'll have to convert something if we get one (or two).
