I'm here, but time delayed :-) No critical failures on the Dell, just performance failure. It can't keep up. You'd think with a box like this: 4GB RAM Dual Xeon (32 bit) PERC3 (LSI based controller) dual channel chan0: RAID1 two disks for OS + pg_xlog chan1: RAID5 14 disks U320 18Gb FreeBSD 4.10 PG 7.4.6 I should get better than a sustained 6MB/s I/O throughput with peaks to 30MB/s and about 30% the tracks/sec others report with name-brand LSI controllers with Opteron systems. The computer is wicked fast, but the I/O can't hold up, and I can't get a straight answer as to why. I'm no closer to solving the vendor problem than anyone else here. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
