Which are the Load-balancing parameters for DIVAR IP and DSA E-series?

Question

Which are the Load-balancing parameters for DIVAR IP and DSA E-series?

Answer

Load balancing is provided with respect to the bandwidth and the number of iSCSI connections and is configurable per IP address (iSCSI target).

For example:

  • Load-balancing parameters are optimized for the DIVAR IP 5000 default configuration (JBOD). When running DIVAR IP 5000 in RAID 1 mode, load-balancing parameters may need adaptation in BVMS.

  • Navigate in the device tree of BVMS Configuration Client to VRM devices > Local VRM > [Context Menu of the storage expansion] > Load Balancing
