Hi All,
I'll give some background first, then explaining my question will make more sense.
We have a vCenter server (5.0) in London, it's got a few clusters associated with it. Both the vCenter server and the hosts within it's various clusters are in the same datacenter physically. We've got two remote sites, another one in the UK and one in Germany. They each have a few esx/esxi servers. The WAN links between the three sites are IPSec site-to-site VPN's over a normal internet line (not sure of the bandwidth off the top of my head).
What we'd like to do is make two new clusters in the London vCenter server, one for each remote site to take advantage of HA, vMotion etc. The VM's at each site will stay local to each site. We are not looking to do geographically distributed clusters or 'stretched clusters'. The storage and everything will remain local to each remote site.
I've been asked to assess the links between each site and gauge whether or not they're suitable enough to handle the communication between the vCenter server and the remote sites.
Looking into it myself, it looks like there is only communication between the vCenter server and the master of each HA cluster, and other minute management information. I haven't been able to find data on about how much traffic can be expected in this scenario but my initial reaction is to say - it wouldn't be that much.
Anyway, very long winded, sorry about that - thanks in advance for any help or advice !!
Kindest Regards,
ALAN
