Hello JK

I think it depends on CPU's, the amount RAM, number of HBA's

But the first thing to do is tune netbackups SIZE_DATA_BUFFER and
NUMBER_DATA_BUFFER for enterprise tape drives

I have seen 25 MBytes/sec on a windows machine to STK9940A drives (30
MBytes/sec native) with
NUMBER_DATA_BUFFER 32
SIZE_DATA_BUFFER 262144 (256K)

There is also the MaximumSGList (see
) ,
which I havn't tried to use yet

Regards
Michael

We are new to windows as a media server and I have some performance
questions for anyone who is using them.
Background:
NBU 5.x
HPDL360 as media server
Windows 2003 Adv Server
HP LT drives
Fabric attached hosts and drives (not host attached)
Data is moved through fabric, not ethernet
Fabric is 2gb for all ports
What type of performance are you seeing with windows media servers given
this configuration (roughly of course)?* Can a windows media server push an
LT drive?* Can a single windows media server push multiple LT drives?
Thanks.
