Introduction
An enclosure containing physical disk drives accessed through Enclosure Management Modules (EMMs) is called a storage enclosure.
A storage enclosure includes various hardware components such as physical disk drives, EMMs, fans, and power supply units (PSUs). You
can attach a single host system to the storage enclosure to access the data on the storage enclosure. You can also establish multiple
physical network paths between the host system and the storage enclosure. Using multiple network paths prevents the loss of a single
path to a storage enclosure from resulting in issues accessing the data on the storage enclosure.
The Storage Enclosure Management software running on a host system manages the storage enclosure. On the host system, the
management software and the storage enclosure communicate management requests and event information using in-band SAS
connections.
