The Cobalt RaQ is a 1U rackmount server product line developed by Cobalt Networks, Inc. (later purchased by Sun Microsystems) featuring a modified Red Hat Linux operating system and a proprietary GUI for server management. The original RaQ systems were equipped with RM5230 or RM5231 CPUs but later models used AMD K6-2 chips and then eventually Intel Pentium III CPUs for the final models.
The Cobalt RaQ was the second product line produced by Cobalt Networks; the first was the Cobalt Qube.
Below is a list of Cobalt RaQ types, and their specs.
850 MHz or 1 GHz (re-release)
Under an OEM arrangement, RaQ 2 units were also produced by Seagate, in the form of the Seagate NasRaQ.
There were variants of the RaQ 3 and RaQ 4 models known as the RaQ 3i or RaQ 4i (SCSI support, two Ethernet connectors, PCI connector), and the RaQ 4r (SCSI support, two Ethernet connectors, and RAID). RAID on these models was accomplished in software using a second IDE channel on the motherboard for the second hard drive. There was also a "bare bones" RaQ 4 model that had a single Ethernet adapter, no external SCSI, and a single hard drive.
The RaQ 3 shipped with Chili!soft ASP support. Cobalt acquired Chili!soft a few months prior to being acquired by Sun.
The RaQ 4 added PHP support to the RaQ 3 payload.
The RaQ XTR was the first 1U server to have four removable hard drives. Unfortunately, the first release was plagued with hardware problems and was recalled. This happened during the Cobalt acquisition, and it took over 6 months to get the XTR re-released. It was never a big seller. The XTR UI was also a "hybrid" between the newer PHP-based Sausalito system and the older Perl-based "special sauce" that powered the RaQ 1 - RaQ 4.
Symantec's Veloci Raptor firewall appliances were also based on the RaQ XTR hardware. These systems were equipped with an additional 2-port network card. Together with the two onboard network cards the system had four network interfaces.
