Eliminating two (2) Oracle (or even DB2) licenses would more than pay for an IFL. (With a little negotiating you might even get 2, or z/VM, or more real storage, etc.) Ask them how many dev/test/failover/DRA machines they have sitting idle 98% of the time. The math isn't hard, and no where near like what the Register "reporter" would like you to believe. After his last article he wrote about this topic, I tried to tell him that hardware costs are only one (relatively small) piece of the total cost picture. He didn't want to hear about it, perhaps because he would actually have to stop and think a bit. To quote the author "The question mainframe shops have to ask IBM is whether a five-processor System z BC can support something akin to this number of VMs running Linux concurrently - and then have Big Blue run benchmarks to prove it." Well, Marist College has a z990 with 3 CPs running 700 Linux systems for its students. I would say a 5-way z9 BC would be able to do at least that well. :) Mark Post ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
