Chapter 2. Introduction to IBM Flex System V7000 Storage Node 

Draft Document for Review January 29, 2013 12:52 pm

The expansion canister connects the expansion disks to the control canister using the SAS2 
6 Gbps chain interface. This module also enables the daisy-chaining of additional expansions 
to be connected behind it to further expand the capacity of the system’s storage. The 
expansion canister is also a Customer Replaceable Unit (CRU). Figure 2-6 on page 52 is a 
picture of the expansion canister with its cover removed.
