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.
