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?
