The array's running RAID 10 with basically the minimum drives for RAID 10; drives are 15K SCSI. I'd think this would be enough. > no RAID controller, lots of cheap disks and thinking > about how to RIGHT set UP gmirror/gstripe/gconcat will > give you best performance. The concern is that this array is mounted over NFS by a number of different servers, all with constant read/write, so this is why we need throughput as high as we can get. Right now, we're only getting a fraction of the performance we theoretically should be getting.
