I have a Windows Master/Media server and 4 Linux red hat advance server 2.1
san media servers.  I cannot ge tthe san media servers to write as fast as
te tape drivers can.    

I have worked with IBM to run some tests on these tape drives, and I have
found that these drives do work at the expected speeds (28 mb/second) under
Redhat with the current driver configuration, and 128kb block size writing
to the tape.  We have not gotten anywhere near these speeds with Netbackup,
even when we adjusted the buffer size to 128kb. Do you have any more ideas
about

how to get these drives working at the proper speed?
