EonStor DS S12/S16/S24 Series Hardware Manual
Single-Controller Model
Single-controller model comes with one controller module. The second controller slot
is filled with a dummy cage.
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 upgradable to a dual controller configuration.
