The Cobalt Qube was a computer server appliance product line, meant to be web servers , developed by Cobalt Networks , Inc. (later purchased by Sun Microsystems ) from 1998 to 2002 featuring a modified Red Hat Linux operating system and a proprietary GUI for server management.

The green LED in the front was Bill Scott's idea. The 2700 was not a development version number but came from the atomic number of cobalt , 27. The Qube 2700 used the RM5230 microprocessor. The next product was called the Qube 2800 before being sold. But, released in 2000,
12-664: A blue color to porcelain and glass. Cobalt blue in impure forms had long been used in Chinese porcelain . In 1742, Swedish chemist Georg Brandt showed that the blue color was due to a previously unidentified metal, cobalt. The first recorded use of cobalt blue as a color name in English was in 1777.

30-538: Was eventually called the Qube 2, leaving the 2800 to designate the system type. The Qube 2 used the RM5231 microprocessor. Under an OEM arrangement, the Qube 2 units were also produced by Gateway in the form of the Gateway Micro Server. The casing featured on these units was black instead of cobalt blue. The Qube 3, released in 2002, used an AMD K6-2 CPU at either 300 MHz or 450 MHz and
36-483: Was the last product in the Qube line. A fourth Qube model was in development but was never released. However, several models were released in the data center -friendly Cobalt RaQ product line after the Cobalt Qube was discontinued.
