Theoretically, with a good enough controller, you can leave WAL on the same partition as your data. With a complex setup like you're looking at, you really will want to do some testing to see what makes the most sense. I can also point you at a company that does modeling of stuff like this; they could actually give you some idea of how well that setup would perform before you buy the hardware. BTW, any test results you can provide back to the community would be most appreciated! -- Jim Nasby jim@xxxxxxxxx EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
