[AusNOG] Back of envelope II

[Darren Moss]

Hey David,

Ahh, very good. That's pretty much what I was referring to.

We only do VM when we absolutely have to... and mostly for Win App customers.

Cheers.

Hi

You can, and that's what I outlined in my response.  The easiest (and  
most transparent) approach is replication behind the virtualisation  
layer so the FC clients don't even see the difference.  We currently  
run SAN virtualisation at our datacentres which allows for not only  
replication, but also simple migration between types storage and even  
between facilities.  It is rather nice (albeit quite expensive).

We also run Dot1Q over EoMPLS between datacentres so we could in  
theory VMotion a VM between datacentres on the fly.  That'd be  
interesting ......


Thanks

David
