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
