RE: IBM i on Power: Was Classes for IBMi/iSeries? -- MIDRANGE-L

I work for a company now that has a large AIX presence and recently acquired my old company which has a large iSeries presence. We are combining both into the Power systems and running them both on the same hardware - all SAN storage with virtualization up the kazoo. This is a very large project but I can already see the acceptance of our os on the Power systems as a great thing. Some of this is a little new to me, but I love learning!

Actually, he included no internal disk at all in this case. It was all SAN
disk. We did not discuss performance, but they are a development software
house, and I would expect them to have unique performance requirements. I
trust that he understood all those configurations.

Which is one of the reasons why Power is so cool. You want SSDs? You want
SAN? You want traditional hard disk internal to your server? And in the
end, the programmers just keep developing, the users just keep running
their apps (albeit a little faster)..

I did mention to him about the Power7 720 I was told about recently. It
included only internal SSDs, and IPL'd in 3.5 minutes.

Trevor,

Did that included SSDs so the programmers don't have to worry about drive
arm access impacting database performance?

Thanks,

In France last week, I was talking with a software company guy who had
just ordered a new Power Systems server to run IBM i. He made the comment
that when he configured it, he included a SAN, PowerVM was a big part of
his new configuration, and there were a bunch of new things that
completely amazed him. This was so different than any previous server he
had built - including all the previous generations.

Then he said, "but the programmers won't know any difference".

And, there's the rub.

As much as I hate to get dragged down on this subject (again) I have to
say that I agree with Trevor.

We are planning a fairly big migration to a nice new pair of mirrored
Power 770's. One of the execs on the planning committee asked me how I
felt about having the iSeries run on a pSeries server...

Being originally from MN, all I can say is Uff Da!
