Online eBay enterprise specialist bargain*hardware sells the NetApp DS14 MK2 AT storage array for £2,500. This consists of a 3U chassis unit with two 440W hot-swappable power supply units, two AT-FCX controller modules and 14 hot-swappable 3.5in 500GB hard disk drives.
On top of that you get dual hot-swappable ESH2 enclosure modules and Multipath HA Storage path redundancy.
You should be able to swap the drives for 1TB or 2TB units (we're not sure about 3TB and bigger hard drives). You will need a NetApp FAS and V- Series controller as well as NetApp's Data ONTAP version 7.2.1 or later. The prices of the drive alone hover around £700 and the chassis weighs a hefty 31Kg.
