Sorry for the OT. I have a call into my vendor about this, but thought
I'd ask here, as some of you probably have experience at this.
I have a VMware ESX 3.5 cluster, 10 hosts, 20 CPUs, with HA and DRS.
What I want to do:
Migrate my existing cluster to new hardware, in the process upgrading
from ESX 3.5 to vSphere v4. That would be first - a set of directions
for that.
THEN, I want to physically move the old ESX 3.5 servers to my D/R hot
site, set it up as a 2nd VMware cluster (I would be wiping these clean,
and then installing vSphere v4). And then keep the two in sync, and be
able to fail over from here to there, and back again, as needed.
I haven't been able to determine if the syncing and failing over is a
feature of vSphere 4; an add-on for it; or needs a 3rd party tool
(something by the FalconStor folks was mentioned to me, but I don't know
any more about that [yet]).
So any advice, pointers, links, horror stories, etc would be greatly
appreciated. Especially since they just told me today that we will
definitely be doing this. In the next 6 weeks. D'OH! Up to this point,
it was more of a "Know what would be nice to have?" sort of discussion ...
Thanks, and sorry for the OT.
