Can I setup a blade cluster for High Availability?

Hello All,

Is it possible to setup a cluster between server blades for High Availability (in the same chassis)? If it is, how?

If there is a way, I think the configuration will vary depending on the chassis, what I meant was, how does it work?
Toni UranjekConsultant/TrainerCommented:
Of course you can, but your chassis is single point of failure.

This is of course possible, and frequently done on blades chassis.

One blade is primary and communicates with the secondary through the network, if the primary dies, the secondary promotes itself to primary.
But the exact workings of course depends of what cluster we are talking about: VMware ESXi?, MS Cluster?, Oracle RAC?, there are hundreds of different clusters, for OS, for Applications, etc.

Better done with 2 computer rooms in different buildings, 2 chassis, and 2 blades? of course, but not everybody has all of those.
