Re: SQL 2000 on SAN

>>From what I am reading, most people say that you should treat your SAN
just like local disks.  So the best disk layout we could ask for would
look like this:

One LUN with RAID 10 space for log files & tempdb
One LUN with preferably RAID 10 space, but RAID 5 is ok for DB files

I just understand the theoretically ideas behind a SAN.  Can one set of
fault tolerant controllers mount two separate LUNs that connect to two
different sets of disks.  Now the above would assume that the provider
has multiple SAN segments that are divided into RAID10 or RAID 5 space,
correct?  If they have all the SAN in one big RAID 5 set then the above
is impossible...

Also, I have read in a few places about optimizing disk I/O on
databases and tempdb by creating one file per CPU so your disk I/O is
better threaded.  Is this still the case when your database files are
located on a SAN volume?

Thank You,
Kevin
