Hitachi Dynamic Load Balancing Controller Symmetric Active- Active Controllers: During normal operation I/O can travel down any available path to any front end port using the native host OS multipathing capabilities. This allows I/O to be balanced over all available paths without impacting performance. Automatic Controller Load Load Balancing Balancing: Controller : If the load on the controllers becomes unbalanced it will automatically be balanced without the host having to adjust it s it s primary primary path. path. SWITCH 1 FE CTRL-0 BE CTRL-0 AMS 2500 High Speed Buses 0 1 2 3 4 5 0 I/O is redirected to less busy controller SWITCH 2 FE CTRL-1 BE CTRL-1 Symmetric Active- Active and Load Balancing Controllers: A Powerful combination! With features traditionally found only in Enterprise class storage arrays, the 2000 Family can dynamically balance I/O over any available path through any front end port on either controller. All this is done without having to load any propriety path management software.
