1 Introduction An enclosure containing physical disk drives accessed through EMMs (Enclosure Management Modules) is called a storage enclosure. A storage enclosure includes various hardware components such as physical disk drives, EMMs, fans, and power supply units(PSUs). One or more host systems attached to the storage enclosure can access the data on the storage enclosure. You can also establish multiple physical network paths between the hosts and the storage enclosure so that loss of any single path (for example, if a host system port stops functioning) does not result in any 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. 4
