Hi,
I posted earlier about some results with this same system using UFS2.
Now trying to test ZFS. This is a Dell PE2950 with two Perc6
controllers and 4 md1000 disk shelves with 750GB drives. 16GB RAM, dual
quad core Xeon. I recompiled our kernel to use the ULE scheduler instead
of default.
Hi Aristedes,
We are/were testing FreeBSD on a Dell PE2950 with a Myricom 10GB
PCI-Express copper CX card. The driver seems mature. In tests out of
the box, I only saw about 3Gbps from iperf (testing against a linux
system...and maybe there are other issues with our environment/that
system
surprise.
thanks,

Should clarify that the first test mentioned below used the same gstripe
setup as the latter one but did not specify any newfs blocksize:
#gstripe label -v -s 128k test /dev/mfid0 /dev/mfid2

Hello,
I think this might be useful information, and am also hoping for a
little input.
We've been doing some FreeBSD benchmarking on Dell PE2950 systems with
Perc6 controllers (dual-quad Xeon, 16GB, Perc6=LSI card, mfi driver,
7.0-RELEASE). There are two controllers in each system, and eac
