I'll be moving a DB from internal RAID-10 SCSI storage to an EMC CX300
FC RAID-10 LUN, bound to the host. I've setup a test host machine and a
test LUN. The /var/lib/pgsql/data folder is sym-linked to a partition on
the LUN. 


Other than the shared_buffers, effective cache size, and sort memory, I
am not sure if I need to change any other parameters in the
postgresql.conf file for getting maximum performance from the EMC box.


Is there a general guideline for setting up postgres database and the
tunable parameters on a SAN, especially for EMC?


Appreciate any help,
