I've just joined the group.
Have just completed the 5.1 5 day course.
i upgraded most servers to gigabit as many of my backups were maxing out
at 11000 kb/sec on 100 mbit ethernet.
Putting gigabit in releived the bottle neck and I get upto 56000 kb/sec
witha max of 77000 kb/sec and two steams going to two 9840C drives.
The SAN disk is StorageTek D178 disk array.
Even Netware backups reduced to one quarter of the elapsed time when the
file system was moved to the D178.
As soon as you remove one constraint, you will find another.
No matter what, gigabit is a big pipe, even when shifting 100+Gb files
around.
/opt/openv/netbackup# cat NET_BUFFER_SZ
131078
/opt/openv/netbackup/db/config# cat NUMBER_DATA_BUFFERS
16
/opt/openv/netbackup/db/config# cat SIZE_DATA_BUFFERS
262144
Hope these figures help.
The Master/media server is a Sun 280R with two processors and 1Gb memory.
Any suggestions on the above sizes?
Thanks
