Connecting SAS cables to expansion enclosures
If you have installed expansion enclosures, you must connect them to a 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; each
set can consist of a maximum of 10 expansion enclosures. Therefore, each control
enclosure can manage up to 20 expansion enclosures. A system that contains two
control enclosures can have up to 40 expansion enclosures.
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 25.
