Re: Virtualizing Tape VIOS vs IBM 1

IBM List for the...
Current SAS Tape card is $1,000
Current 4GB Fiber card is $ 2,500
Current 8GB Fiber Card is $3,500
Only have a *Guesstimate* on a 24port Fiber SW with 8 active ports $12,000

So if you need to add the Switch you are taking $13,000+ additional cost to
go fiber

Ok, I'll admit that I was never shown the prices for the fiber tape
library, switches, cards, etc. But if they're even close, why would one
order SAS over FC? I gotta believe that using fewer ports has to have a
significant factor in reducing costs. Especially with Power 8's being
extremely limited on expansion slots for now.
Sure, adding a switch in there will increase some knowledge needed. But
it will help to reduce the complexity of having to flop devices around,
varying on/off, etc.

Rob, i believe you did but you were talking about NPIV IIRC. In this case
we are both asking about SAS ports which are not as nice as FC (Worst
part?
in my case the machine HAS 2 DualPort 8G HBAs but no FC switch so i cant
do
NPIV even if the tape library had FC).

It's better than that. I use the same port from multiple lpars at the
same time! Yes, I have had three lpars doing saves simultaneously out
that same port, virtualized from vios, at the same time and got better
performance than each lpar having their own fiber card back on Power 6.
Didn't I already post this?

When hosting IBM i on IBM i I can place the SAS physical adapter in the
Host and using vSCSI adatpers I can setup it up and all you have to do

is

Vary the Drive Off in 1 partition and Vary on in the other. I have done
this with a single drive on a single card.
Works Great and no HMC to mess with to move the tape drive.

With Power8 unless you buy something bigger than an 8core you have very
limited cards slots. I would really like to use a single SAS card with
multiple ports in different partitions at the same time. Can this be

done

in VIOS and/or IBM I?

Example1: SAS Tape Card assigned to VIOS and Use Port1 for IBM i

Partition

A while using Port 2 for IBM i Partition B?

Example2: Same as #1 but IBM i is the Host?
