Hi all,
We've got two Sun Fire V480Rs with the following configuration:
# /usr/platform/sun4u/sbin/prtdiag
System Configuration: Sun Microsystems sun4u Sun Fire 480R
System clock frequency: 150 MHz
Memory size: 4096 Megabytes

The machines are configured in a Veritas cluster, using the gem cards as
heartbeat and cassini
gigabit ethernet connected to a Fast Iron 1500 switch.
Veritas 3.5MP2 is installed on both machines and a Sun Storedge array is
connected to four fibre-channel
cards. Both machines share a clustered filesystem using SanPoint
filesystem 3.5MP2. The version of
vxfs installed on the machine is 3.5_REV-MP2d,RP2.
Both SunFire machines are running Solaris 9 with the August 2003 patch
set installed.
We're having throughput problems when writing to the Sun machine, while
reads are fast. Using ftp
as a benchmark, we're seeing 40-45Mb/s during a read from a 1gig file in
/tmp and 15-16Mb/s when
writing a file to the same partition. We don't know if the veritas
filesystem is the culprit or are there
are some system variables we can tweak.
Any insight is welcomed.
Thanks
Mark
