IBM Flex System V7000 Storage Node Introduction and Implementation Guide
The Flex System V7000 Storage Node has two available slots in each control canister for
populating with host network adapters. The adapters in each of the node canisters must be of
the same type in each of the slots; so the adapters are installed in pairs (one adapter per
node canister) and the following adapter configurations are supported for the entire Flex

2.4.1 Control canister
The control canister is responsible for the management of all the virtualization, RAID
functions, advanced features and functions of the IBM Flex System V7000 Storage Node and
all command and IO to its internal drive slots and the expansions that it is connected to. The
control canister is a Customer Replaceable Unit (CRU). Figure 2-3 is a picture of the control
canister with its cover removed.

In Figure 2-3, the processor (A) is a quad core Jasper. There are also two DIMMs which make
up the cache memory and the battery backup unit (B) which beside the control canister is also
a Customer Replaceable Unit (CRU).

As we discussed above, the two host network adapter card locations (C and D) can also be
seen. These provide the connections to the Flex System Enterprise Chassis through the
midplane and the switch modules. It is important to remember that both control canisters must
be populated with the same type of host network adapter cards in each of these locations.
