2 server rooms on one "site" or 2 sites
Posted on 2013-01-27
Hi, sorry for the vague title.
I have inherited a setup where we have a single site with 2 server rooms. This is good; dual core, dual fabric san, etc nearly everything is replicated however moving forward - new SAN and hypervisor we need to decide whether we are going to treat each server room as a separate site. As far as I see it:
+ storage available to both server rooms
+ easy to live migrate VMs
- difficult to determine what is running where
- can be a challenge to manage
+ you know what service/server is running in each
+ theoretically easier management
- how to live migrate vms between clusters
- more thought required when planning clustered services
We would be looking at an active/active setup, hence the difficultly in deciding.
Any thoughts? We're going Hyper V 2012 btw.
