StorageLoader Performance
The
StorageLoader is
not efficiently
backing up data
• Check the network bandwidth from the host system. If you are backing up data
over a network, consider comparing to a local-only backup.
• Verify that the host application and the device drivers are installed with the
most recent patches to support the tape drive and the loader.
• Make sure that you don’t have any bottlenecks in the path between the tape
drive and the SAS host controller. If you use SAS extenders, make sure that the
extenders have the same or higher maximum speed than the tape drive and
host controller.
• Connect the loader to an LVD SCSI bus and make sure there are no SE
devices on the same bus, otherwise this will cause the entire bus to negotiate
down to SE speed.
• Clean the tape drive. See the installation and user guide, Chapter 6.1. Using
the Cleaning Cartridge.
• Try a new cartridge. A marginal cartridge can cause performance problems
due to bad spots on the tape requiring retries.
• Backing up compressed data lowers performance.
• Check the size of the files. Small file size can impact performance.
