Having shot my mouth and hoping to extort some sushi the hardware
vs software raid testing should be happening this Sunday. It'll be
like the Super Bowl, but for sysadmin geeks.
With a weekly growth-rate of 250+Gb and less than 400G left on my
storage I don't have that much time to test.
However, for the interested:
Dual Xeon 2.8 Ghz
2Gb RAM
1 ATA 40Gb system disk
24 465Gb SATA disks
2 3ware 9550SX-12MI controllers with 224Mb
Config:
2 RAID-50 arrays of 12 disks each.
Glued together in a single LVM volume of 9Tb
bonnie++ output:
# sync ; bonnie++ -n 1 -m spinvis -u 0 -s 20480 -f -b -d .
