Our CIO has suggested that we get a Sun 15K to house all of our databases. This has some advantages (communication between the various boxes would be much faster) but I have some performance concerns. Specifically, our main OLTP database would go down from 18 spindles to 8 spindles. Mirroring will take away 4 of those leaving 4 spindles. The vendor (Sun) was recommending striping across all 4 spindles. He said we don't need to worry about i/o issues because there will be a large cache. I'm skeptical and argued for cutting them in half (striping 2 and 2). We could then at least seperate the redo logs from the datafiles (probably putting them with the oracle executables and some other files). The Sun rep kept talking up how much more powerful the CPUs were and I kept saying, "but we're not CPU bound, we don't need any more CPU". If anyone can either a) tell me I'm worrying for nothing b) recommend a better way to stripe/distribute my files c) provide references or experience to show this is a bad idea I'd really appreciate it.
