Re: Virtual disks for an i partition

[DrFranken <midrange@xxxxxxxxxxxx>]

Rob,

	We will likely just make the LS disk bigger at that point. Especially 
for the VERY low I/O rates we see on iDevCloud there is little reason 
for them to have all the disks the same size. Remember the size 
restriction is just for the Load Source, other disks can be all manner 
of wacky sizes if you feel the need to do that.

	With POWER7 I think the smallest physical disk you can purchase today 
is 139GB. I think if you're migrating older 3 1/2" SAS drives you might 
have 70s in there yet. So except for the virtual environment the minimum 
size requirement isn't really a restriction any more.
