Makes one wonder if Linux is reasonably usable with 3ware. ;-)
Does anyone have any bonnie++ results for Linux software RAID 5? I know
software RAID 5 does not really lend itself to a performant software
implementation, but the results would be interesting to see, none the
less.
I don't have any hard numbers, but one of my colleagues just doesn't use
the 3Ware hardware RAID features because of the performance issues,
building his RAID 5 (or possibly RAID 6) arrays in software. Performance
screams (=fast).
If he is using 3ware raid cards below 95xx series, raid 5 performance
sucks due to the lack of a large RAM buffer. 3ware 95xx cards should
have good performance with raid 5 implementations.
