A quick and easy guide to setting up the Dell PowerEdge C8000

Refer to the C8000XD owner's manual for more zoning options used in different

hard drive configurations.

The C8220 and C8220X compute

sleds have an internal SAS RAID controller

to connect to internal drives. To connect

the C8000XD storage sleds to the

compute sleds, an external SAS controller

must be installed in the available PCI

Express slot. The external SAS controller

is a dual-port card with four external

connections. SAS cables must be

connected between these ports and the

C8000XD storage sled.

Figure 14 shows the C8220X

connected to two C8000XD storage sled

in a Single Port mode configuration. In

this configuration, one end of a SAS cable

is plugged into the top port of the

C8220X external controller and the other

end is connected to port A1 on the

C8000XD. This provides connection to the

first C8000XD sled. To connect the second C8000XD, plug one end of the SAS cable to

port B1 on the first storage sled and connect the other end to the second C8000XD in

port A1. This provides communication to both storage sleds and gives maximum storage

capacity for the C8220X compute sled.

Because the C8000 chassis can be configured in multiple ways, there are several

cabling possibilities. For example, in a configuration with a C8220X compute sled and

C8000XD storage sled in the same chassis, the SAS cable would stretch across the

chassis. For this situation and as a best practice in general, take the following two notes

into consideration.

NOTE: When cabling the compute sleds to the storage sleds, it is best practice to

have them positioned on top of each other in the server rack so they are lined up

vertically and cable between those units. Stretching cables across the chassis is messier

and can restrict airflow.
