Hard Disk for Sun Ultra 20

I recently obtained a Sun Ultra 20, an X86 AMD Optron, system with no hard disks.

I know that it can work with 2 SATA disks.
Is there any limit restriction to the capacities of each disks?
I obtained a 1TB WD SATA disk which can slide and get connected to the pair of connectors fastened to the body of the system, but I cannot find any obvious means of securing the disk - while connected.
Does it require any type of brackets?

If you do have a Sun Ultra 20 with hard disks, could you be kind enough to open the side panel and comment on the above questions?

I had installed Solaris 10 on another Sun Ultra 20 with disks, without any issues.

Do you know if Solaris 11 can be installed without any issues?

Thank you.


  • Looks like the disk drives require a 1" SPUD bracket. Same bracket that most Sun systems used in that era. Probably part number 540-6562 would work just fine.

    No clue if a 1TB drive will be recognized in that system. Do you have a U20 or a U20-M2? If the former, you may run into issues with the BIOS supporting that size of drive. The largest supported drive is a 250GB drive...

    No clue about Solaris 11 either but my money would be on it running just fine on that system. Supported is another issue...
