Has anyone had any experience with an RS12/FC. This is a fibre channel raid controller. I have 12 drives each in two chassis with a fibre channel controller in each. I'm trying to figure out the best setup for redundancy and performance. In my performance testing I am maxing out at 68 MB/sec read rate. Whether I have a RAID 0+1 across 4 drives or RAID 0 across 8 drives, no difference. I tried two RAID 0's across 4 drives each, and softwaore stripe them using Win2k, still same performance, maybe 1 MB/sec faster. So where is my bottleneck. The firbe channel is 100MB/sec. So is the loss in overhead on the FC protocol? Maybe the controller can't handly any faster transfers no matter how many drives I have. These are 160 MB/Sec scsi drives, by the way. I don't think is a bus issue on the PC. I've tried a generic old Pentium 233 and a Netserver XEON 550 4 Processor with a controller in a 64bit slot. Still same performance. Any insight or opinion?
