Spuddly writes "Linux guru Jonathan Corbet of LWN analyzes an experimental new design for Linux's virtual memory system that would turn a large amount of system RAM into a fast RAM disk with automatic sync to magnetic media.We have not yet reached a point where systems — even high-end boxes — come with a terabyte of installed memory. But products like those from Violin Memory make it clear that the day is coming; So perhaps it's time for some wild ideas. And there is no better source for such ideas than Daniel Philips, whose Ramback patch has stirred up a bit of discussion this week. The core idea behind Ramback is that all of that memory is turned into a ramdisk, but with a persistent device attached to it."
