RE: Guest Partitions

["Jerry C. Adams" <midrange@xxxxxxxx>]

So I wouldn't have to license IBM i for the client partition as, I think, I
would under the "classic" LPAR scenario, right?  That is, both partitions
(host and client) would use the same (single copy) of IBM i?  When I
mentioned partitions to the BP he said that would add costs to the proposal.
Right now (Model 250) we have two [2] 8.6 gig drives mirrored.  The BP said
the smallest disk available for the Power 7 is 146 gig.  So I could just
"carve out" a network server device storage area in that same 146 gig drive
without the need for additional disk drives?

If I don't need an additional IBM i license nor additional disk drives or
memory, this sounds like the way to go.  In a small operation such as ours,
I would not imagine that disk contention would be an issue.

Jerry,

   This is *exactly one of the benefits of hosting i with i. In this 
case it sounds as if you would have production owning all the disk 
units. Some network server storage spaces are created on the production 
partition to become the 'disk units' for the test/dev partition which is 
hosted.  The console is through the HMC. The optical drive is 'passed 
through' to the client partition.  Ethernet is through the Host Ethernet 
Adapter. The two partitions appears as two separate machines, different 
IP, Security, PTFs, Products loaded, etc.  In short, perfect for what 
you want.
