I am doing some research to see if a VTL will help my NDMP performance. Currently I backup my Net App environment over the LAN. I am looking to improve backup and restore performance.
I have a LTO-3 Tape library that can be fiber attached to the Net App filer. My concern is that the Net App filer will not be able to stream to the tape drives and I will kill my performance since the tape will have to do lots of re-positioning and start and stop. I was thinking a VTL would be able to match the speed of the net app box thus the performance would be optimized. Questions: I have newer and older Net App boxes, assuming a 2GB san, what performance can I expect using NDMP? Do you see an advantage using VTL in place of multiple LTO-3 drives? How many streams are possible (Using NBU 6.x)? Do the number of streams help in a VTL environment? how about a tape environment? Any recommendations on performance tuning with NBU 6 and NDMP? Thanks in advance!
