Storage data sample rate

The tool supports 5 minutes sample rate for storages and SAN devices except:

  • IBM Storwize/FlashSystem/SVC, Lenovo V Series: 10 minutes can be set up, it is usefully especially for storages with thousands of volumes which are not able to provide all data within 5 minutes.
    You can configure it in the storage properties.
    When you increase to 10 minute then you must kill svcperf.pl process running for that storage.

  • IBM XIV, A9K: they use 10 minutes sample rate as default

  • Brocade Network Advisor(BNA): it uses 10 minutes sample rate as default
