Message-ID: <3E56910F.6050509@lamp-post.net> (raw)
I was wondering if it would be possible to set aside a large (larger)
amount of system memory to act as cache for software raid.
I have a few xeon systems here with 4-8gb of memory in them and based on
watching the performance of some mylex raid cards
jump up when we did a memory upgrade from 64mb -> 128mb I was wondering
if the same would occur in linux.
If this is even something doable (tweakable) Im wondering what the perf
gain from allocating say 2 or 4gb just to raid cache would be.
Comments ?
