Boris,
When I was doing some testing earlier I could see in the logs that the
buffer sizes were only changing when I modified the
size_data_buffers_ndmp value. If there is a way to set the size on the
Celera I would guess that would work as well. I haven't figured out how
to set the MOVER_RECORD_SIZE on the NetApp. I'm kind of hoping that the
value being passed by Veritas using the size_data_buffers_ndmp value is
setting it.
Thanks,
Jeff

Hello Jeff,
I just have SIZE_DATA_BUFFERS on the netbackup media servers and the
buffer size on our EMC Celerras set to 256k. I don't have
SIZE_DATA_BUFFERS_NDMP set at all, and I can see quite good
performance on my LTO3 tape drives, as I pointed out 75mg/s on the
UNIX and 65mg/s on Windows.
