(as a note..) Per nickmbailey, testing shows that there is little/no benefit to separating commit log and data dirs on virtualized disk (or SSD), because the win from this practice comes when the head doesn't move between appends to the commit log. Because the head must be assumed to always be moving on shared disk (and because there is no head to move on SSD), you'd be better off with a one-disk-larger ephemeral stripe for both data and commit log. =Rob
