Usaually SAN and NAS is used for several good reasons...the two main are... 1) High availability - When you have your database files on SAN/NAS then you can bring ur database on another server when the primary goes down. Obviously you have to use a cluster or Big IP (F5) on the front. 2) reduce redundancy -A unix userid with home directory attached to a paticular NFS drive on NAS/SAN, will able to see all his files when he logs into other servers.

so far I heard "Net App" is low cost including with Raid 5.

my reasons to recommend an external storage was..

the database size is 36GB, and according to many documents i have read, SAN is not cost effevtive unless populated by a large numbers of drives !!, now for the client the cost is not the factor.. given the situation.. wouldnt a SAN be an overkill ?
NO DBA or SYS ADMIN skills to manage the SAN !!

Can you share some of the reasons related to your decision in choosing a direct-attach storage (DAS) instead of a SAN? In general, a SAN is a much smarter choice than DAS.

      list, one of our clietns are going to by SAN, the current oracle databases take around 
      36GB of storage.... i dnt understand there reason to go for SAN, i sugguested to buy an external storage 
      box instead. How can i justify my desicion ? (cost of not the factor) 

      TIA
