Dell has launched new single-socket servers for small and medium-size businesses, replenishing its overhauled PowerEdge line of servers.

The PowerEdge T300, with a tower chassis, and PowerEdge R300, a rack server, are designed to consume less power and include system management tools to better manage IT tasks, Dell said. The servers have quad-core Xeon processors and provide memory expandability and redundancy features, the company said.

The servers run on processors including Intel's Celeron, Core 2 and Xeon chips. The PowerEdge R300 also supports a low-voltage Xeon processor, said Lionel Menchaca, a Dell blogger.

The servers come with hot-pluggable hard drives, which allow hard drives to be replaced without powering down the server, Dell said. They also come with redundant power supplies to boost system reliability. Both servers include Dell's OpenManage system management tools to help administer and manage IT system resources.

The servers hold up to 24GB of RAM and come with integrated graphics controllers. The T300 supports up to 4TB of storage, while the R300 supports up to 2TB of storage. The servers will support Windows Server 2008, Red Hat Linux Enterprise 5 and Suse Linux Enterprise Server 9 and 10.

The R300 server is priced starting at US$1,249 (just over £600), and the T300 starts at $999 (£500).
