The way HA works is ACS will monitor your VMs and HV, if one HV goes

storage those VMs were using and this can only happen if you use
shared
storage. Do I make sense?
Hmm. Not 100% sure I understand, but getting closer :)
So, "shared storage" would be a separate "storage server", plus at
least 1 extra for a failover? And, if I understand correctly, this
"HA" option is all configured and enabled within the CloudStack
management console itself?
Sorry if I'm not picking up quickly, but I'm getting it a bit more
clear understanding with a few questions for clarification sake.
Basically, say I'd like to start a small initial setup to offer cloud
VM's (or popular term "vps / virtual private server" in the cloud).
I'll have one server strictly for the CS management console, I'll have
one HV + 1 extra for failover for CPU/Memory, and then I'll have a
storage server + another for failover. Would this make sense?
Yes, this makes sense. The failover SAN/storage is optional.
Good luck!
