IDE RAID Examined
Bender writes "The Tech Report has an interesting article comparing IDE RAID controllers from four of the top manufacturers. The article serves as more than just a straight product comparison, because the author has included tests for different RAID levels and different numbers of drives, plus a comprehensive series of benchmarks intended to isolate the performance quirks of each RAID controller card at each RAID level. The results raise questions about whether IDE RAID can really take the place of a more expensive SCSI storage subsystem in workstation or small-scale server environments. Worthwhile reading for the curious sysadmin." I personally would love to hear any ide-raid stories that slashdotters might have.
What does your CPU utilization look like when you're doing that 180 MBytes/sec? You're doing software-raid, yes? (You didn't mention a RAID controller) -- are you doing RAID-5?
Do you think you could pump the 20-gig file over gigabit ethernet at a saturated 125 MB/sec?
That is to say, for sequential read, would this sub-$10k solution be a media server limited only by gigabit ethernet bandwidth? Holy cow!
How about sequential write? Can you copy a 20-gig file from the network at the same speed? (i.e. sequential write.)
What does the highest your CPU utilization gets to? Are both processors used?
Very interesting...
