Running a Sun Solaris 9 E250 and need advice or suggestions on what type of external hard disks are compatible and or available. It's an old machine and is due for replacement soon but in the short term need an external hard drive for backup etc as the partner/backup machine has just died.
The E250 is a PCI bus based machine, so most things are pretty easy to connect still. An old A1000/D1000 T3 or similar would work fine with a PCI HBA but almost anything that can be PCI connected will work, or you could backup over the network to another machine that has simpler ( eg. USB ) attached storage if it short term.
