2. If you want to connect additional Fibre Channel cables, make sure to connect the same number of
cables to each canister.
Figure 135 on page 125 shows an example Storwize V5020 configuration with four Fibre Channel
cables connected to each node canister.

3. If a control enclosure is already installed, you can optionally add Fibre Channel connections between
all the control enclosures.
• This involves both the physical installation of the cables and configuring the correct zoning on the
Fibre Channel switches.
• Configure the network so that every node canister has at least two connections to every node
canister in a different control enclosure.
• You must configure the network before you attempt to add a control enclosure to an existing system.
Connecting a control enclosure to a host with onboard SAS connectors
When you install a control enclosure, you can connect it to a host with SAS cables. On Storwize V5020
systems, you can use the 12 Gbps onboard host SAS ports or an optional 4-port 12 Gbps SAS host
interface adapter. Onboard SAS host ports are not available on Storwize V5010, Storwize V5030, or
Storwize V5030F systems.
About this task
Two types of SAS cables are used for host attachment, depending on the requirements of the host.
