I ran across this a while ago, it basically a PCI card with lots of SDRAM on it that acts like disk space. Don't know much more than the company propaganda but it's supposed to play nice with linux. They have various sizes, some with backup power for when the machine is off. Should give a speed adavantages over a disk... and not have the overhead of a RAMdisk. Might be worth a look. http://www.platypus.net/ Charlie On Fri, 16 Mar 2001, Austad, Jay wrote: > I tested them for a very high capacity mail server to increase the speed of > the queue.
