Optimizing Data Protection for SAP HANA performance

When SAP HANA backs up data, it sends data for all SAP HANA services, such as nameserver and indexserver in parallel from all nodes. If data is intended to go directly to tape, the number of allowed mount points for the IBM Storage Protect™ node must be adjusted.

When you are planning to store data in a disk storage pool and then migrate it to tape, be aware that SAP HANA data is restored in the order that is determined by HANA. Use either disk storage pools or tapes with enough mount points to optimize the restore by reducing the number of tape-seeks and mounts. If the data to be restored for all nodes is on a single tape drive, it can lead to increased restore times or deadlocks.
