Hi,
I used sysbasher and the web interface on the san. I figure
that it gives an ok view of the load on the san. It corresponds ok with timed
cp's.
Also i did some loops that just copied to and from the
san. But generally it's just a rough average, and i'm just wondering if
it's similar in performance to other configurations.
The hardware is:
2 fujitsusiemens RX200s3 servers with emulex 11003
hbas and two dualcore cpus and 4gb memory.
Connected is a SX60 san with an extra controller and
powersupply.
Mvh / Kind regards

No I do not but if you elaborate on the tests performed or have atest script I would be glad run some bench marks.
It would also be helpful to know the hardware you are running on.

Hi Dan,
Have you got any performance figures on the OCFS2 ?
My GFS is currently delivering the following performance:
(2 nodes, 2gbit FC HBAs multipath'ed + 1 Fujitsu SAN (SX60) 7x250gb raid 5.)
Writes: average 100mb/sec, 200 files/sec (with simple cp/rm)
Writes: max 150mb/sec, 250files/sec (with simple cp/rm)
Reads: average 160mb/sec (cat > dev/null - uncached)
Reads: average 1150mb/sec (cat > dev/null - cached)
Anybody have a feeling about this performance level?
Regards
Kristoffer

Ok Here is what I did to get it working:
used RHCS to manage the cluster services
used CLVM to manage the LVM metadata across cluster
Coded a "locking_type = 3" in the LVM.CONF file
Used OCFS2 to cluster and manage the filesystems across cluster.
Configuration is
2 node cluster runing nfs
vitural IPAddr service to allow clients to mount the drives via NFS
All appears to be working fine. I can fail over the services manually or even boot a server and the failover works great.
Now the big question....is this supported by redhat and oracle ...hmmmm
Thanks to all who helped get this working...
