We are just under 2TB with SAP.  We are sitting on a shark.  We are using 10
3590E1A drives attached to 2 San Data Gateways attached to 2 2109 S16
switches with 4 fibre adapters on the host.  Our tsm server and database
server are the same server.  We backup in around 7-8 hours for a full
backup.

Good luck
Becky

Subject: Sizing for 2 TB Oracle DB backup


I'd be interested to hear if anyone out there is backing up a 2TB or bigger
Oracle DB from IBM Enterprise Storage Server (SHARK). We are likely to have
to backup such a beast in the near future and I'm wondering how we can
protect so much data. We will in all likelihood be backing up the flashcopy
(ie using TDP for ESS and TDP for Oracle) but how many SAN attached drives
are needed?  Can anyone offer any experiences or suggestions as to what
sort of a configuration will accommodate such a volume of data?

Thanks for any input,
