....and in a similar vein, ATAoE ; either Coraid stuff or the the free one in the Linux kernel. Its heavily used in some shops that use virtual farms with SANS as it's cheap/free and works over existing hardware but only at layer 2. I even run it at home (!) - and it's a surprisingly easy way to have a shelf of storage hanging off the back of a server, with 4GB of cache for each set of 4 disks per box. Stand too close can feel the wind from it, especially if RAIDed. Depends if there's much call for VM-ing in your shop in the future? Gord -- NNNN
