Dedicated LUN and sizing for VBR servers

[icebun]

Our VBR servers are VMs running in VA mode on Windows server 2008.

If I use a dedicated LUN just for the VBR servers rather than one that has other VMs runnng on it, will there will a noticiable improvement in performance?

Should this LUN also be big enough to accomondate the largest VMDK file I am likely to need backing up as well?


Thanks.

Hello,

If I use a dedicated LUN just for the VBR servers rather than one that has other VMs runnng on it, will there will a noticiable improvement in performance?

It depends on how heavily other VMs use disk IOPS under that LUN, but I don't think there would be a noticeable improvement if using a dedicated one.

Should this LUN also be big enough to accomondate the largest VMDK file I am likely to need backing up as well?
