Ever work with Sun servers? Yeah, you could swap out cards, CPU, ram, drive, power, without halting or rebooting the OS. But not just Sun servers. This is not a feature unique to Alphaservers/VMS.

It was originally a DEC specific design copied/stolen by others. DEC created the design concept of a common back plane. Other than some logic switches to control power/enabling, there was nothing it provided. Every machine was completely customizable.
I'm not a hardware buy, but I believe this is a carry over from the VAX days long before there was SUN.

Nope! I didn't know that. Very interesting.
The Alphas had a motherboard and daughterboard - and the daughterboard was a generalized bus, so a single slot could have a RAM or CPU slot in it --- were Sun servers capable of this too? Or was a RAM slot a RAM slot and a CPU slot a CPU slot and they were not interchangeable?
I'm curious because I've never seen any other machines with a generalized CPU/RAM bus, I'm curious if Sun hardware supported this? If it did, can you remember the model numbers so I can read up on it?
