Connecting expansion enclosures to the control enclosure
If you have installed expansion enclosures in the rack, you must connect them to the control enclosure.
About this task
This task applies if you are installing one or more expansion enclosures. Each control enclosure in the system can manage two sets of expansion enclosures.
The number of SAS chains and enclosures varies per each type
of system, as shown in Table 1.
System | Expansion ports | Number of SAS chains supported | Control enclosures per system | Expansion enclosures per chain | Maximum Number of Enclosures |
---|---|---|---|---|---|
Storwize® V5010 and Storwize V5020 | Port 1 only | 1 | 1 | 10 | 11 |
Storwize V5030 and Storwize V5030F | Port 1 and Port 2 | 2 | 1 | 10 | 21 |
Each set of expansion enclosures is connected together sequentially through the IN and OUT SAS ports, forming a chain with a control enclosure at the end of the chain.
Note: When connecting SAS cables between enclosures, you must follow a
list of guidelines to ensure that your configuration is valid. Do not begin connecting
the cables until you have read SAS cabling guidelines.
Procedure
To install the cables, complete the following steps.
