Re: Fibre Channel Tape Sharing on Guest Partition

I concur, i've just finished installing 2 ps700 blades with IVM (vios but
without the HMC) using NPIV and it was pretty easy. And next week i go to a
client to migrate from a badly installed VIOS to a real Dual VIOS config
with MPIO at the VIOS and LIC level (2 FC cards for each VIOS and 2 vSCSI
adapters to each partition so each partition has 1 path on each VIOS No
NPIV 'cause they are still at v6r1m1). It was harder to find all the
relevant documents and best practices, once you find that it's just a
matter of doing it.
As soon as i've got time i'll make a nice page with all the info i
collected from here and the web.

We have redundant VIOS partitions running V7000 disk and TS3500 tape via
NPIV to 15 different IBM i partitions. It's really not that difficult once
you get the first one complete(and the first one is not that hard).

If you have VIOS in the mix you can virtualize like crazy. Both tap and
disk. I just finished a major install with Pete that's all Fiber Channel
storage through SAN Switches and VIO to V3700. Once a few bits are set up
in VIOS you simply create storage on the SAN and attach it to whichever
partition that needs it. Shazam more disk. Tape is the same.

Since VIOS is needed for other advanced functions as well such as
mobility, memory sharing and more, it makes sense that VIOS would bring all
that support first.

Slightly OT, but I wonder if anyone knows why Fibre Channel support is

so difficult to virtualize? Just in general terms.

Fibre connected SAN storage is a huge benefit to most business

configurations.

Even a tiny system like a DS3500 can support the i - rather the DS3500

supports IBM VIOS 2.1.3 wit h IBM i 6.1 or later. And it can support flash
copy and other. (Okay, for comparison, you can can configure 18TB of raw
storage (i.e. about 13TB in RAID 5) for about $16K. That's significant
change, but how much would it cost to put that much storage directly on an
i?

Or are there just better solutions than I, being way out of date, am

unaware of?

Anyways, it would seem that fibre connections would be one of the
first things virtualized, but it usually seems to be one of the last.
Judging by "i" and VMWare. The zSeries machines can all virtualize
fibre connections (FICON and FibreChannel) without breaking a sweat,
but then, those machines do not have any internal DASD options. :)
