Yes its reachable, sustainable is another question...

Our exchange servers routinely average about 30,000 KB/sec on LTO2
tapes.
This is on NB 4.5 FP8, all master/media servers are HP-UX with FC
connections.

Subject: [Veritas-bu] NBU 5.0 LTO's Gen 2

Hello group:
I will like to find out if the 32MB/sec throughput is 
reachable?.Currently I can achieve 20-25Mb/sec, but the average fall 
down to the 16MB/sec. The backup's jobs I'm using for testing is one 
660GB Filesystem with multiple data streams(6) that reside in the backup

server. This jobs, is not going through the network.

My configuration is as follows:
Server Sun 440 with three dual jni FC HBA cards connect directly to the 
library.
Library Sun L500 with six LTO's gen 2
NBU 5.0 with their corresponding patches.
Solaris 9.0 with their latest patches.
The variables for tunning base on the the logs from bptm are:
NUMBERS_DATA_BUFFERS=256
SIZE_DATA_BUFFERS=26144

Any idea or comment will be appreciate.
Thanks;
-Eduardo
