Subj:   Re: Teradata And EMC SAN space
 
From:   Cornelius Meade

Thomas,

The question of the use of SAN's with Teradata seems to crop up from time to time and I believe NCR's official position is that this is not a recommended configuration due the high I/O demands Teradata makes on its storage subsystem, which tend to exceed the ability of current SAN technology to deliver adequate performance.

In reality, I suspect there is probably some gray area where depending on the size of your system and the expected workload, this might provide adequate performance but I think the general consensus is that a SAN based architecture is not a viable solution for a robust Teradata system expected to deliver high performance at this time.....
