Re: Guest Partition Storage Configuration

Hi, Jim:

But why is this even necessary, when the virtual disk space is carved out from single level storage on the host system, if hosted on i5/OS, and (presumably) is itself spread across all available drives, heads and arms?

Or, are you talking specifically about the case where the virtual disk is provided by VIOS, and hosted on a SAN of some kind?

Thanks for any further clarifications you can provide.

The reason is to provide IBM i with arms to manage. Creating one
storage space would be the same as giving an IBM i instance only one
disk drive. Bad plan from an I/O performance stand point. The
architecture just works better when it's allowed to do what it is
designed to do.

Jim, curious, I never heard of having a storage space only based on 35GB??,
could you elaborate on this part. If I need 150GB of space I would just
create 1 storage space.

Yes, the partition will be created with a HMC
