The other linux box is my production SAN.
it is newer (E200i controller, SAS 15k disks, 4GB RAM, hdparam is about 130MB/sec) and I cannot use for testing.
It is fileio on an entire partition of a logical RAID5 disk.
I am testing DSS V6 trial (latest build) on an older box to see if its performance is good enough to use in production.
Since write performance with iSCSI is poor, I tested with samba to ensure that my older hardware is ok.
