Re: [Xen-users] best setup for live failover

[Donny Brooks <dbrooks@xxxxxxxxxxxxxxxx>]

 Also let me explain my planned roadmap. Instead of buying huge Dell T710 style 
servers with cpu, ram, and disks, from this point on I would like to just have 
a NAS or two and then have some small 1U server that have the cpu and ram to 
run the guests on. That is the main reason for the live failover.
