Light weight servers have been gathering steam recently. Targeted at focused markets like hosting and Web 2.0 they feature the old school architecture of placing one CPU per server and running one OS/application on that server. The new twist here is that they can pack up to 12 servers per one 3U enclosure.
Below, Dell Data Center Solutions chief architect Jimmy Pike takes us through a short whiteboard discussion on how Moore’s law has driven us to multi-core architectures and virtualization and how, in the case of very focused applications, that same law is bringing us back to the future.
Some of the points Jimmy makes:
- Given Moore’s law its implausible to continue to drive higher and higher clock rates. This has given rise to multi core architecture.
- Native demand of applications on servers hasn’t kept paced with Moore’s law. This has resulted in virtualizaton, allowing you in effect to run multiple servers on a single system.
- This same law is also driving us in the opposite direction, to light weight servers which feature a simple one server/one OS architecture in a very energy efficient, cost effective manner targeted at focused applications.
