I know this has been discussed in various forms over the years, but I'm
specifically wondering about the current state of hardware
I have a long history with TSM on AIX.  It's stable, familiar and an I/O
powerhouse.  Our Unix admins also favor AIX for serious, heavy-duty
workloads.

We are looking at refreshing our largest P570 now.  I discussed this with
our unix admin, who also has a very high opinion of IBM.  He said that
current SandyBridge implementations can really make Linux a contender in
terms of I/O and CPU performance.  And at about 1/7th the cost.

I normally dismiss Linux because I was under the impression that you would
need many inexpensive servers to equal one P-series for I/O.  It wouldn't
be worth it with the added management of dealing with multiple TSM
Servers.  Now with DB2, TSM seems to be going more towards the monolithic
direction if anything.
But If I can get a single 32-core, 128GB ram intel server that can
actually push multiple 10gbe and 8gb FC interfaces I am finding Linux a
little more attractive.

Does anyone have any stories,  gotchas, or opinions with replacing a
P-series host with a modern Intel system 1 for 1?


Regards,
Shawn
