HP StoreOnce Backup System Concepts and Configuration Guidelines (BB877-90913, November 2013)

HP StoreEver Tape Libraries
HP Half-Height Tape Drives for LTO 5 and LTO 6 have equal Data Transfer Rates to the Full-Height
versions. This allows an HP StoreEver MSL 2024 to have two Half-Height LTO Drives with no
decrease in performance giving maximum “performance density”.
Backup Application
To achieve optimum offload performance the backup application must be capable of multiplexing
offload data to a HP LTO Ultrium Tape, and the backup application server must be capable of
ingesting multiple streams from the HP StoreOnce Backup System at the same speed as it can write
to HP LTO Ultrium Tape.
HP StoreOnce Optimum Tape Offload Configuration
The table below represents the optimum configuration of Tape Drives and Data Streams for
offloading from an HP StoreOnce Backup System.
