Log-structured file systems: There's one in every SSDLog-structured file systems: There's one in every SSDPosted Sep 18, 2009 22:02 UTC (Fri) by paravoid (subscriber, #32869)In reply to: Log-structured file systems: There's one in every SSD by Yorick Parent article: Log-structured file systems: There's one in every SSD
That's kind of interesting, considering that Sun's OpenStorage solution (which uses ZFS) uses SSDs for caches -- which I presume has them at 100% full capacity.

If want to use SSDs for caching the last thing you want is to keep them at
100% capacity - it takes too long to kick things out of the cache, just when you need to put something new in.

I think the idea is they are physically at 100% capacity, even if not logically so. That is, they've probably hit full at some point.
Well, that's my guess, since it makes the most sense.

FWIW they have separate read and write caches (both SSD).
