Connecting optional expansion enclosures to the Storwize V7000 Gen3 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 chains of expansion enclosures; each chain can consist of a maximum of 10 2U
expansion enclosures. Therefore, each control enclosure can support up to 20U of expansion enclosures.
A system that contains two control enclosures can support up to 40U of expansion enclosures.
Note: When connecting SAS cables between enclosures, you must follow a list of guidelines to ensure
that your conguration is valid. Do not begin connecting the cables until you have read Figure 140 on page
126.
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 Figure 140 on page 126.
a) Connect SAS port 1 of the upper node canister in the control enclosure to SAS port 1 of the left
expansion canister in the rst expansion enclosure.
b) Connect SAS port 1 of the lower node canister in the control enclosure to SAS port 1 of the right
expansion canister in the rst expansion enclosure.
