SAN Storage

Hi, we will  have a SUSE Linux Ent OES network as our prmary file server for 200 users in the next 2 months or so
also have a seperate SQL Server for about 50 users
what we are looking for, open to opinions are SAN
we will be installing a new server, that will run SUSE Linux, OES2, BUT we want all the user files/data to be stored on a SAN.
any suggestions
budget - $10,000 - $20,000
ideally something with a RAID 5,6,10, 50?
would SATA drives be best?  or SAS - I heard SAS better with 100-200 users at any given time, logging in, acess data
what we have looked at are
Sun - http://www.sun.com/storage/disk_systems/expansion/
Dell - Equallogic of MD3000/3000i
EMC - seems out of our range. budget wise.

Why do you want a SAN? are you intending to cluster your servers or do you just want less performance for your money?

well we thought by getting a mid range server - RAID1
and not using it for storage will save us $$$ on the server
but by spending $$ on a SAN, would get us better productivity/redundancy for our data.
am I wrong in thinking like this?

You save money by not buying disks to put in the servers but spend same amount of money buying disks for the SAN. You don't magically gain IOPS by coughing up an extra $5,000 for a pair of controllers and a disk cage and seperating them from the server by adding fibre or iSCSI.

Chose clustering software before looking at SAN or it's just waste of money.
Get your performance statistics - what your Disk IOPS, bandwidth, read/write ratios are. Those numbers will be extremely valuable in sizing the proper solution. When submitting for quotes from different vendors, let them know your statistics and ask them to size a solution based off of that.
