IBM licensed Intel's blade technology a couple of years ago and married it with IBM's own BladeCenter. This combination is now taking market share on an accelerating basis. The reasons to assume ongoing success include a double-digit cost advantage over traditional 1U and 2U rack-mounted servers, up to 4 processors on a blade, and well-conceived power management that reduces HVAC costs and infrastructure requirements.
My preferred architecture for most applications going forward is simple:
- A blade-based server farm. IBM is the leader in blade technology.
- A storage-area network (SAN) that eliminates direct-connect server disks. Low-costs SANs now start at $5,000. Here I lean towards EMC/Dell.
