Re: why SAN ? why not external storage ?

[Arun Annamalai]

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.   -Arun.

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. ----- Original Message ----- From: Rahul To: Multiple recipients of list ORACLE-L Sent: Wednesday, March 12, 2003 1:33 AM Subject: why SAN ? why not external storage ? 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 rahul
