The main features and benefits of the Primergy TX120 server are: -reduced active power, down to 163W and even lower when using Celeron processor that translates into a 40% increased energy efficiency; -reduced space and size, fully a third smaller footprint and a fourth less volume occupied so it is well suited for offices and needs no special space to operate; -advanced cooling technologies like "heat-pipe" and "straight line cooling" turn the server into a much quieter machine; -RAID1 and hot-plug HDD, error-proof memory, Xeon UP processor, server operating system pre-installed and integrated Remote Management Controller make from the Primergy TX120 a top of the line server. Users may customize their server's hardware; a 1.866GHz Intel dual-core Xeon 3040 is available right next to a slower and cheaper Intel Celeron. The server supports up to 8GB of ECC RAM packed in four DIMMs and up to four SAS hot-plug hard-disks in RAID configuration.
