Upgrading Single Controller to Dual Controller System
If the model name of a single controller RAID/JBOD is designated with the letter “S”,
it can be upgraded into a dual-controller configuration by adding another controller
module and firmware upgrade (see software manual). If the model name is
designated with a “G”, it is not upgradeable to a dual controller configuration.
