Overview of steps to connect storage expansion enclosures to a storage subsystem
To connect storage expansion enclosures to the storage subsystem, complete the following steps:
1.Follow the instructions in the Installation, User's, and Maintenance Guide for your storage expansion enclosure and the Rack Installation Instructions to set up and mount the storage expansion enclosures.
2.Select a cabling topology applicable to the number of ESMs in the storage expansion enclosures that you will connect to the DS3200. If you are connecting external storage expansion enclosures to the DS3200, make sure that each storage expansion enclosure contains at least four drives before you power it on. In addition, make sure that the DS3200 storage subsystem contains at least four drives before you power it on.
“DS3200 storage subsystem drive cabling topologies” describes the recommended schemes for cabling storage expansion enclosures with one ESM or two ESMs to the DS3200 and to each other (if you are connecting more than one storage expansion enclosure).
3.Follow the cabling diagram for your chosen topology.
4.If required, set unique enclosure IDs for all storage expansion enclosures that are cabled to the DS3200. See the DS3000 Storage Manager Version 2 Installation and Support Guide for information about setting the enclosure ID.
The DS3200 storage subsystem locates the drives in the storage expansion enclosures after you
DS3200 storage subsystem drive cabling topologies
This section describes the following preferred cabling topologies for cabling storage expansion enclosures to the DS3200 storage subsystem:
v“One
v“One
v“One
v“One
Each example provides redundant paths to the drives. If one of these examples is suitable for your hardware and application, complete the cabling connections as shown in the illustrations. If you have hardware other than what is shown in these examples to include in your topology, use these examples as a starting point for creating your specific topology.
Important:
1.The DS3200 supports the connection of a maximum of three storage expansion enclosures.
2.The DS3200 supports one redundant
3.In storage expansion enclosures that are connected to a
