At first launch from Cobalt Networks there were three hardware configuracions, one with 300MHz CPU and two with 450 MHz AMD:

Code: Select all

Q39 302 PAU - Qube 3 with 300MHz, 32MB SDRAM, 10.2GB HDD
Q39 6J4 T19U - Qube 3 (Business Edition) with 300MHz, 64MB SDRAM, 20.4GB HDD, SCSI interface and Web Caching
Q36 CH8 U20U - Qube 3 (Professional Edition) with 450MHz, 128MB SDRAM, 2x20.4GB HDD with RAID 1 mirroring, SCSI interface and Web Caching

Later, after the Sun adquisition, the 450 MHz AMD was the only option, diferencing models in RAM, external SCSI and the software payload:

Code: Select all

CBT-Q3STDMM - Standard Plus Edition 450 MHZ CPU, 64 MB of SDRAM, one 20 GB HDD.
CBT-Q3BUSMM - Business Plus Edition 450 MHZ CPU, 256 MB of SDRAM, one 40 GB HDD, Web Caching,IPSec VPN.
CBT-Q3PROMM - Professional Plus Edition 450 MHZ CPU, 512 MB of SDRAM, two 40 GB HDDs with RAID 1, Web Caching, IPSec VPN

And at the end there was a OS upgrade:

Code: Select all

CBT-Q30202UPGCD Upgrade CD-ROM to Sun Cobalt OS 6.4

You can install what cd version you want. Obviously the last version is the best but you can look for the Strongbolt 1 distribution with CentOS 4 and Bluquartz panel (and new ROM) to have the latest possible system. Not sure, but if I recall correctly you can install the RaQ4 OS directly and RaQ 550 OS if you upgrade the ROM. Forget Strongbolt 2.

I don't know anything the type you have but the differences with other Qube 3 of the same specs must be the software included. All the Cobalt servers included development tools but maybe your Qube lacks/has something.
