Re: [Veritas-bu] Real World NBU Buffer settings Win2k3
For what it’s worth
64kb buffer size
10GB backbone/2Gb FC
I have played around with all sorts of buffer sizes but in our
mixed environment 64 works best.
But 4 days for 1.7TB seems more like the norm to me. We have
several servers verging on 1TB that can take 36 hours.

got any real world experience on buffer settings:
San Media, connected to 2GB Fabric attached 8 LTO4 Drives.
to drive availability, Multiplexing onto one drive.
problem: One volume (1,7tb in size) takes over 4 days to fully complete.
the Tuning Guide and Technote 244602, but I tried some settings, only to find
the backup would not even mount tape correctly.
back to "no" settings at the mo.
are generic files/folders, mixture of large and small sizes. But 1.7TB's in my
view should be done quicker. Also Data is compressed.
