1 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.
2 Connecting the enclosure The storage enclosure is connected to a host server by using one or both of the two EMMs. The EMMs are named as EMM 0 and EMM 1. You can connect the enclosure in three different configurations: ● Single Port Configuration ● Redundant Configuration ● Multi-chain Configuration Topics: • • • Before you begin Procedure to connect the enclosure Cabling your enclosure Before you begin WARNING: Whenever you lift the system, get others to assist you.
● To remove the SAS cable, pull the pull-tab to release the cable from the connector on the EMM and the host system. Figure 1. Connecting a SAS cable a. Pull-tab b. SAS cable c. SAS port NOTE: ● To make sure that the controller is correctly installed, see your RAID controller documentation at https:// www.dell.com/storagecontrollermanuals. ● For more information about single port configuration, redundant configuration, multi-chain configuration, see Cabling Your Enclosure.
Related concepts Single port configuration on page 7 Redundant configuration on page 8 Multi-chain configuration on page 8 Single port configuration Single port configuration supports up to four enclosures. The enclosures are daisy-chained with one of the enclosures connected to a single port on the controller card. Figure 2.
Redundant configuration In Redundant configuration, the enclosures are daisy-chained with one of the enclosures connected to both the ports on the controller card. Figure 3. Redundant configuration Multi-chain configuration Multi-chain configuration supports up to eight enclosures. The first four enclosures are daisy-chained with one of the enclosures connected to a single port on the controller card.

3 Managing your storage enclosure Physical disk drive storage within the enclosure can be configured using either the BIOS configuration utility or OpenManage Server Administrator. For optimal management and serviceability of your enclosure, it is recommended that you use OpenManage Server Administrator. NOTE: Online configuration, enclosure status, and active event notification is supported only with OpenManage Server Administrator version 6.2 or later.
4 Downloading firmware You can download firmware updates for storage enclosures using the Dell Update Package available at https://www.dell.com/ support.
5 Getting help Topics: • • • Locating your system service tag Documentation feedback Related documentation Locating your system service tag Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code and Service Tag are found on the back of the system by pulling out the luggage tag. Alternatively, the information may be on a sticker on the chassis. This information is used by Dell to route support calls to the appropriate personnel.
