Enclosures are rack-mounted hardware that contains several components of the system. Enclosures can be used to extend the capacity of the system. The term enclosure is also used to describe the hardware and other parts that are plugged into the enclosure.
When enclosures are cabled together to form the system, each enclosure is assigned a unique enclosure ID. However, you can change an enclosure ID at a later time.
The system has two different types of enclosures: control enclosures and expansion enclosures. A control enclosure manages your storage systems, communicates with the host, and manages interfaces. In addition, each control enclosure can have multiple attached expansion enclosures, which expand the available capacity of the existing control enclosure.Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP systems can support one control enclosure with one chain of optional expansion enclosures. Lenovo Storage V5030 and Lenovo Storage V5030F systems can support up to two control enclosures with one or two chains of expansion enclosures per control enclosure.
Enclosure objects report the connectivity of the enclosure.
