Add a new disk to Ultra 10

I am using an ultra 10 with Solaris 9....

I want to add a new disk that I can play around with partitions, maybe mirroring - that type of thing.. Its a test box..

I need help on what I can buy - and what I need, cables etc to add new disk and install it...

Anyone got any pointers?

Ultra 10 workstations used regular old IDE disks, so anything should work. On Sun's website they have a Solaris x86 hardware compatibility list you could look at too if you're wondering about a specific model. But basically any IDE disk should be usable in one of those machines. I know I just put a Maxtor 40 GB IDE drive into an Ultra 10 the other day at work and had no problems.
