Oh my, it would appear that IBM has discovered 'ECS' -- Extended Core Storage,
which has been used on Cyber systems for a number of years.

I used to work on the PLATO system, which ran on antiquated Cybers 73's at
the time. They had 2MW of ECS which they used for swapping (you didn't get
rolled to disk, ever) and when that wasn't enough they built AMS (Aux. Mass
Storage) which could go up to 4 or 8MW.

I don't know if NOS used ECS for roll-outs or not, since we never really used
NOS very much.
