The logical layout of the components of a computer system or network and their interconnections. Topology deals

Things to Know – Host Channels
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray, use proper
antistatic protection when you handle tray components.
Each controller has from two to six host ports.
Two of the host ports are standard and support 6-Gb/s SAS data rates.
Two to four of the host ports are optional, and, if present, are located on a host interface card (HIC). The
following types of HICs are supported:
NOTE In configurations where a HIC does not exist, the space is covered with a blank faceplate.
— Two SAS connectors at 6-Gb/s
— Four iSCSI connectors at 1-Gb/s
— Two iSCSI connectors at 10-Gb/s
— Four FC connectors at 8-Gb/s
