Here is what I like to see: A Sun X4540 "Thumper" with 45 of its 47 disk drive (one removed for testing) lights blinking furiously at an estimated peak IO bandwith of 400 MBytes/sec read / 300 MBytes/sec write. Configured as a 46-physical-disk "raidz" (essentially RAID5) array, this system does everything a Netapp or similar "magic box" would do except NDMP, at half the price, and with full Solaris OS functionality thrown in for extra. (Can you run BIND or Apache on your storage applicance?) Everything is hot swappable, about 19T as-configured, spread out across 6 SATA controllers, fits in 4U, field-upgradeable to double that, and we got the whole kit and caboodle for half list price under a Sun educational grant program. This could be the THE BEST BOX EVER.
