described by the graphics. If you have hardware other than what is shown in these
examples to include in your topology, use these examples as a starting point for
creating your specific topology.
Important: The DS3950 supports the connection of a maximum of six storage
expansion enclosures per redundant drive channel pair. The DS3950
supports one redundant drive channel pair.
If you are using fiber-optic cables, install SFP modules into the ports that will
receive the cables before installing the cables.
Figure 35 and shows the locations of controllers A and B, the single-ported Fibre
Channel host channels, Ethernet ports, and dual-ported Fibre Channel drive
channels at the back of the DS3950 storage subsystem.
Note: Your DS3950 hardware might differ slightly from the following illustration.
Notes:
1.
EXP810 and EXP395 storage expansion enclosures can be intermixed behind a
DS3950 drive channel.
2. To cable EXP810 storage expansion enclosures with a DS3950, you must
purchase the Attach EXP810 to DS3950 Activation feature option.
