This is really discouraging. Based on these newsgroup postings I am thinking that the Sun StorageTek 2540 was not a good investment for me, especially given that the $23K for it came right out of my own paycheck and it took me 6 months of frustration (first shipment was damaged) to receive it. Regardless, this was the best I was able to afford unless I built the drive array myself. The page at http://www.sun.com/storagetek/disk_systems/workgroup/2540/benchmarks.jsp claims "546.22 MBPS" for the large file processing benchmark. So I go to look at the actual SPC2 full disclosure report and see that for one stream, the average data rate is 105MB/second (compared with 102MB/second with RAID-5), and rises to 284MB/second with 10 streams. The product obviously performs much better for reads than it does for writes and is better for multi-user performance than single-user. It seems like I am getting a good bit more performance from my own setup than what the official benchmark suggests (they used 72MB drives, with 24-drives total) so it seems that everything is working fine. This is a lesson for me, and I have certainly learned a fair amount about drive arrays, fiber channel, and ZFS, in the process.
