Is this single-file bandwidth or multiple-file/thread bandwidth? According to Sun's own benchmark data, the 2530 was capable of 20MB/second more than the 2540 on writes for a single large file, and the difference went away after that. For multi-user activity the throughput clearly improves to be similar to what you describe. Most people are likely interested in maximizing multi-user performance, and particularly for reads. Visit http://www.storageperformance.org/results/benchmark_results_spc2/#sun_spc2 to see the various benchmark results. According to these results, for large-file writes the 2530/2540 compares well with other StorageTek products, including the more expensive 6140 and 6540 arrays. It also compares well with similarly-sized storage products from other vendors.
