Hi Pete, I hope the Brewers game was fun! Mike Schmidt let me know yesterday that we are using RAID 1 (mirrored) on our idd.unidata.ucar.edu cluster nodes. Moreover, at one time he ran at least one of the nodes with a 40 GB queue on a machine with 72 GB of RAM. Whether or not the size of your queue as a fraction of total RAM is important on your system is unknown to us. Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
