Hi. I have a small job to do here, creating a list of what type of Linux load/services/apps is best fit to run on z, compared to x86.
Oracle DBs have been a huge win for us, much though it will pain the new Sun evangelists over there to hear us say it. On modern x86 boxes the smallest systems we can buy are grossly overspecced in the number of cores required. This means that while the hardware is cheap (a couple of boxes for a production RAC, a couple of boxes for a DR RAC, Stress and PPTE environments, and so on will probably add up to a fraction of the cost of the IFLs and memory required to support the workload), the software licensing is hideous. When I co-presented on our experiences at a the Brisbane conference IBM put on a few weeks ago I noted we'd had a push to put our "odds and sods" tier 2 DBs onto Lintel hardware to avoid spending up on expensive Z class hardware, but the decision was reversed because it turned out we'd need to license something in the order of 50 cores to get appropriate redundancy/resiliance. We didn't need anything like 50 cores of compute power, but you can only buy Intel kit 4 cores at a time. The numbers look even worse with the Sun Niagra boxes. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
