Also, another way to improve performance is to add another gig card and
install Sun Trunking software, assuming the switch you are connected to has
ether channel cabapility. My NB master is a Sun 880 , failover master is
also 880, and 2 media servers are also 880's. All 3 have with 4 X 1.2 GHz
procs and 8 gigs of ram. Other media server has 4 X 900 MHz procs and 8 gigs
of ram. Also, 4 have dual gig cars going to a Cisco 6509 with Sun Trunking
on the server side, to have a huge pipe to push data to tape, and ether
channel enabled on the cisco, to push data to master/media servers as fast
as the clients can feed it. I have 1-10 drive LTO2 STK library, 1-10 drive
STK DLT-7k library, and 8 -9940b drives in a STK Powderhorn silo. All
clients, if possible, have a dedicated gig/quad,hme card directly connected
to the Cisco. LTO's are fc going to dual brocades. Depending on how
optimized the client connection is plays a huge factor in backup speeds.
When I notice a client running slower than I think I should, the problem is
always the same, the SA who owns the server forgot to hard code the ndd
settings into a startup script.

Subject: RES: [Veritas-bu] Netbackup clients with gigabit interface
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
