For "cheap" storage the most popular solution in the HEP (High Energy
Physics) community are linux boxes with 3ware raid controllers. The
Areca controllers have also appeared lately in some places and since
the driver is now part of the kernel I expect to see more of them.
A few Sun thumpers started to show up (just one site added something
around 1PB recently with them) and they are very good solutions if your
space is limited (48 sata slots in 4U). If you bought the ZFS hype (I
am not convinced yet) they are even more attractive.
