Connecting Expansion Enclosures To The Control Enclosure - IBM Storwize V5000 Gen2 Quick Installation Manual

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 12 on page
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" on page 24.
Procedure
To install the cables, complete the following steps.
1. Using the supplied SAS cables, connect the control enclosure to the expansion enclosure at rack
position 1, as shown in the following figures.
a) Connect SAS port 1 of the left node canister in the control enclosure to SAS port 1 of the left
expansion canister in the first expansion enclosure.
b) Connect SAS port 1 of the right node canister in the control enclosure to SAS port 1 of the right
expansion canister in the first expansion enclosure.
Figure 18 on page 22 shows how to connect SAS cables on a Storwize V5010 system.
