About the Enclosure Connections

The RAID array enclosure is connected to a host via two hot-pluggable RAID controller modules.
The RAID controller modules are identified as RAID controller module 0 and RAID controller
module 1 (see Figure1-4).
Each RAID controller module has at least one SAS In port connector that provides the direct
connection to the host or node. A second SAS In port connector is available on the optional dual-
port RAID controller. SAS In port connectors are labeled In-0 and, if using the optional controller,
In-1(see Figure1-5).
NOTE: When you cable from a host server to an MD3000 SAS In port connector, either Out port of the server’s
HBA can be used.
