Cabling the Storage Systems
This section provides information for connecting your cluster to a storage system.
Storage management can be either in-band through the SAS connection, or out-of-band using an
Ethernet connection. For out-of-band storage management, cable the Ethernet ports on the storage array
to the public network.
NOTE: Dell recommends that you configure your Dell PowerVault MD3000 to use both in-band and out-of-band
management paths. Establishing all management connections to a RAID enclosure provides additional paths in the
case of a management connection failure.
Cabling the Standalone Server in Redundant Configuration With Dual SAS 5/E HBAs
Each server attaches to the storage system using one SAS 5/E HBA and two SAS cables. In this
configuration, there are redundant storage paths from the server to the storage system. If a component
fails in the storage path such as the port, the cable, or the storage controller, the multi-path software
automatically reroutes the I/O requests to the alternate path so that the storage array continues to
operate without interruption.
To cable the server:
1
Install a SAS cable from the server HBA 1 port 0 to the RAID controller module 0 port In 0.
2 Install a SAS cable from the server HBA 2 port 0 to the RAID controller module 1 port In 0.
