Karen and Sean,
You mention ZFS version 6 do yo mean that you are running s10u2_06? If
so, then definitely you want to upgrade to the RR version of s10u2 which
is s10u2_09a.
Additionally, I've just putback the latest feature set and bugfixes
which will be part of s10u3_03. There were some additional performance
fixes which may really benefit plus it will provide hot spares support.
Once this build is available I would highly recommend that you guys take
it for a spin (works great on Thumper).
Thanks,
George

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 months.
Today we are watching 750 Sun Ray servers and 30,000 employees. Lets see
1) Solaris 10
2) ZFS version 6
3) T2000 32x1000 with the poorer performing drives that come with the
Niagara
We need a short term solution. Niagara engineering has given us two more
of the internal drives so we can max out the Niagara with 4 internal
drives. This is the hardware we need to use this week. . When we get a
new box, more drives we will reconfigure.
Our graphs have 5000 data points per month, 140 data points per day. we
can stand to lose data.
my suggestion was one drive as the system volume and the remaining three
drives as one big zfs volume , probably raidz.
thanks

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 IOPS. (Even with the cache on.)

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 (apache, tomcat, etc) directory. We also have batch jobs that run
throughout the day, I would say we read 2 to 3 times more than we write.
