Re: Guest Partition OS Requirements on Power8

IBM i Licensing is the same. The difference is that if IBM i is running your Host partition then that will consume a portion of your IBM i cores that you have licensed. If you are using VIOS then those cores come out of the pool of processors NOT Licensed for IBM i. So since you've already paid for VIOS (It's part of PowerVM) therefor you save money using VIOS.... Maybe - because maybe you already have enough IBM i Licensed.

Rob,

Are you stating that the IBM I core licensing is different when using VIOS compared to non VIOS.
How many active cores do you have?.
How many IBM I core licenses do you have?

I have 8 active cores, but only 3 IBM I licenses.

I would say that not having to buy the IBM i per-core license for the hosting partition is a very good reason to use VIOS (VIOS uses at least 0,5 core each, more if it had a lot of resources)... but the DCR is a good idea anyways.

IDK. My boss still thinks VIOS is some "wave of the future". But if
we can do all of our virtualization necessary from IBM i then that
significantly reduces the expense by not tying up hardware for VIOS,
not having to support vios and learning all that stuff. and so on.

Rob,

If and when your DCR would be completed, would you no longer use VIOS
for partitioning?

I am using fiber. I was using SCSI with LTO3 back on Power 6's but
even all those switched to fiber LTO4's.
Description: 8 Gigabit PCI Express Dual Port Fibre Channel Adapter
Feature
code: 5735 Right now it's virtualized from VIOS to four lpars of IBM i.
I've submitted a design change request to allow me to bypass vios.

Sue / Rob,

Am I correct that if the tape library was SAS attached as opposed to
fiber, then it could be virtualized, Rob I believe this is your config.
From a performance standpoint, I've always opted with fiber over SAS
attached.

From a future roadmap viewpoint, what are the options available for
tape virtualization, fiber or SAS?

What are the IBM I virtualization options (host and/or guest) for
fiber attached tape, 577D?

At the present time, fibre attached tape (577D is the CCIN for feature
5735) cannot be virtualized by IBM i to any i client.

DLPARing the adapter from one partition to another is still a
reasonable way to go for fibre attached tape. I used to do this on
our systems by sending SSH commands to the HMC from my batch job stream.
