What if you can't give ZFS whole disks? I run snv_38 on the Optiplex

Our application Canary has approx 750 clients uploading to the server
every 10 mins, that's approx 108,000 gzip tarballs per day writing to
the /upload directory. The parser untars the tarball which consists of
8 ascii files into the /archives directory. /app is our application and
tools
Given the amount of I/O wouldn't it make sense to get more drives
involved or something that has cache on the front end or both? If you're
really pushing the amount of I/O you're alluding too - Hard to tell
without all the details - then you're probably going to hit a limitation
on the drive
Hi Torrey; we are the cobblers kids. We borrowed this T2000 from
Niagara engineering after we did some performance tests for them. I am
trying to get a thumper to run this data set. This could take up to 3-4
