Hi,
I am wondering if there is a guideline on how to configure ZFS on a
server with Oracle database?
Start with the Best Practices Guide
http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide
We are experiencing some slowness on writes to ZFS filesystem. It take
about 530ms to write a 2k data.
This seems unusual, unless the EMC is mismatched wrt how they may have
implemented cache flush. The issues around this are described in the Evil
Tuning Guide

We are running Solaris 10 u5 127127-11 and the back-end storage is a
RAID5 EMC EMX.
This is a small database with about 18gb storage allocated.
Is there a tunable parameters that we can apply to ZFS to make it a
little faster for writes.
Oracle is using 8k block size, can we match zfs block size to oracle
without destroying the data?
$ zpool status zpraid0_e2
pool: zpraid0_e2

scrub: none requested
config:
