Using performance sensors

Data Protection for SAP uses sensors that observe incoming and outgoing data streams. They measure throughput and the idle time of the I/O threads in comparison to the duration of the backup. This function provides a way to determine whether the streams of incoming and outgoing Data Protection for SAP data are balanced.

The method of transferring data packages depends on how IBM Storage Protect™ is configured. In a standard configuration, the data packages are sent from the IBM Storage Protect API client through the network to the backup server. In an environment that is configured for LAN-free operations, the data packages are processed by the IBM Storage Protect API client and the IBM Storage Protect Storage Agent.

When a backup operation begins, filling the buffers is necessary before the effects of a bottleneck are viewable.
