Did you up your NBU buffer settings to account for the increased
performance of LTO-4?

You can check this technote to determine which settings to check and if
your media server has enough resources to push these upgraded drives:

I've heard that 1MB is useful for the buffer size (1048576) but you'll
need to test to really nail it down.

Subject: [Veritas-bu] LTO-4 on Linux

 

Folks,

 

Has anybody out there configured LTO-4 drives on Linux Red Hat ES 4?  I
recently swapped out a pair of LTO-2 drives for LTO-4 drives on a v5.1
Media Server and have seen no throughput performance improvement.  I did
the same test on a Windows 2003 Server using the same data and saw
significant improvement, but the Windows OS has a specific driver for
the LTO-4.  Linux uses the mt driver, but I can't see anything on the
web specifically about tuning the mt driver for LTO-4.

 

Regards,
