We are using the 9940B drives in a STK Powderhorn silo. We have 20 drives shared between 2 TSM servers using the Gresham software.
As to the reliability, I've seen the same problems quoted by others. However, these seem to dissipate with use, like a long painful burn in period. Right now we still average 2 stuck tapes per month in these drives. These require a service call to have a tech come out and remove the tape. The Gresham software seems solid with some nice utilities to help manage the drives. You'll learn to love/hate the qlock_drive utility, as it shows which drives are locked to which server. If the process that locked the drive, expires ??, then you will have to manually issue unlock and dismount commands. Some additional maintenance but we have monitoring scripts that page us when something happens. Good Luck.
