Re: why SAN ? why not external storage ?

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.


Sr oracle dba

  my reasons to recommend an external storage was..

  1. 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 ?
  2. 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)
