To be clear, we're talking about battery-backed RAM (specifically MOS RAM) there, right?

- IncRnd 6y agoI don't know how the solid state storage was implemented. There are bunches of Cray brochures on the Internet that might have that information.
- monocasa 6y agoIt's not an SSD; they're referring to their main RAM as solid state storage to differentiate it from core memory.

- walrus01 6y agoI don't think it was battery backed by anything in the Cray, though I could be wrong. The general idea being that the Cray would be installed in a facility that should have massive whole AC circuit, true online type UPS, and generators backing that up.
- monocasa 6y agoI think they're talking about the (not battery backed) SRAM, that would have been referred to as solid state storage to differentiate it from core memory technology. The gigabytes of SRAM used as main RAM you could stick on a Cray was a key differentiator for the platform (and would be still today).
