I want my Availability

I wanted to do a knock off the Dire Strait's tune - Money for Nothing and then change the "I want my MTV" into "I want my Availability" - VKernel will then hire a Dire Straits cover band to perform it somewhere.

Availability vs. Capacity - is one better than the other?

Are there types of Availability?

Virtual John writes about High Availability (HA) vs. Continuous Availability (CA)

"In plain English this means, if one of your hosts in a cluster of VMWare Servers goes away the VMs will reboot elsewhere. Reboot = downtime, so is this high availability? Or just higher availability than no fault tolerance?"

It could be a important misnomer - the VM's with HA will be expected to not have any interruption of business service (enter VMotion) and voila - "I want my Availability".
