3-2 620J Storage Enclosure Installation and Overview Guide
Things to Know – Connecting the Storage
Enclosure to a Host
You can connect a storage enclosure to a new host or to an existing host. Before you
connect a storage enclosure to an existing host, you must answer these questions:
•
How many storage enclosures does this host support? This information is located in
the storage array profile for your storage array.
•
What is the cabling configuration for the storage array? See “ Things to Know – Basic
Cabling Configurations “ on page 3-5 .
•
Is the storage array receiving power? No, see “ Steps to Connect – Storage
Enclosures with the Power Off “ on page 3-3 .
•
Is the storage array transferring I/O data? Yes, see “ Steps to Connect – Storage
Enclosure with the Power On “ on page 3-4 .
Things to Know – Connecting the Storage
Enclosure to Another Storage Enclosure
The ESM in each storage enclosure has three SAS connectors. Below two of the
connectors is an arrow pointing up. Below the expansion connector on the far right is
an arrow pointing down. When connecting from an ESM in one storage enclosure to an
ESM in another storage enclosure, make sure that you use connectors with arrows
pointing in opposite directions.
ESMs are connected to ESMs in other storage enclosures (or most hosts) via cables with
a standard 4-lane SFF8088 connector on each end. Ease-of-use implies that the cables
have a “universal key.” Otherwise, the two ends of the cables might need to be switched
with each other so that they match with the proper ESM connectors. High-quality,
compatible cables with universal keys from LSI are available from your system supplier.
