Why is my Fujitsu ETERNUS LT40 S2 performance so bad?
- JJessica DillonAug 15, 2025
Poor Fujitsu Storage performance can stem from several factors. Try using a new cartridge, as a marginal one can cause performance issues due to bad spots on the tape. Backing up data that compresses poorly or is already compressed can lower performance. Small file sizes can also impact performance. Confirm that your backup application uses block sizes of at least 32KB, preferably 64KB, referring to its documentation for details. Check the network bandwidth from the host computer, comparing to a local-only backup if backing up over a network. Ensure the backup server has enough memory to handle the backup or restore bandwidth. Cleaning the tape drive may also help.
