Controllers
Since the EqualLogic PS Series was introduced, there have been several different array models released
with new features, better performance and greater storage capacity. The storage array controllers
were improved to take advantage of advances in the underlying networking and storage technologies.
2.3.1
Controller Types
Array controllers can be identified and differentiated by the controller "type" designation. Each
controller type will have a different colored label to help quickly identify the controller type. Table 3
lists each Dell EqualLogic controller along with some characteristics about each.
