The new baby of the Dell server family, the PowerEdge T20, is designed for small businesses looking for a platform for shared storage and to host applications such as email, web and database servers. Alternatively it could be used as a departmental or branch server where it faces stiff competition from arch-rival HP with its ProLiant MicroServer Gen 8.Small choicesThe days when you could more or less specify your own Dell server from an extensive list of options are long gone, especially when it comes to entry-level systems like the PowerEdge T20. Some buyers may be disappointed by this but it does make life easier with just the one freestanding mini-tower chassis available for the T20 fitted with a single 290W power supply.Neither as well-built or compact as the MicroServer Gen8, the Dell chassis is of workmanlike construction with a removable side panel giving plenty of access to the internals, including a compact mini-ATX motherboard mounted towards the bottom of the tower. Up to six SATA hard disks can be accommodated inside the casing with metalwork provided to accommodate two 3.5-inch disks at the bottom and two more in the top of the tower. Unfortunately the disks can't be hot-swapped and the two at the top are only accessible by removing the front panel. Moreover, although a further two 2.5-inch drives can be fitted in the space otherwise used to take an optical drive, the on-board controller only has four SATA ports which means fitting an additional adapter if you want to use all the available bays.
