The last time I had a Veritas Consultant came out to help upgrade
NetBackup, she recommend to put no more than 4 drives per HBA in our
environment. If you only have 1 HBA, you can still drive 8 drives but
it might take a performance hit (but it might still be an acceptable
speed depends on your environment and backup window).
