Load Balancing (NT)
Online load balancing allows for the configuration of the data path to the RA4000. When more
than one RA4000 and Fibre Channel Host Adapter are on the same Fibre Channel loop, the
system can be configured to use a different Fibre Channel Host Adapter to distribute all of the
traffic to each RA4000 and all of the logical drives on it. Using different paths to each array
increases performance by decreasing the workload of the Fibre Channel Host Adapter.
