I have a ProLiant 12 bay server with a raid controller with 2x6 drives each in raid 5 configuration, 1 being a cache drive and the other being a parity drive for my external 40 drive jbod disk array. I thought was cool idea, but after I ran it, seem like more was being put into the swap than I originally thought would actually happen. I discontinued the swap file all together. Seems like mine just wants to use the swap even before ran out of ram.
