Connecting hosts

Two servers/one dual-ported HBA per server/dual path

Connecting switch attach configurations 

Two servers/two switches

Connecting remote management hosts

The management host directly manages systems out-of-band over an Ethernet network. 

1.

Connect an Ethernet cable to the Ethernet management port on each controller.

2.

Connect the other end of each Ethernet cable to a network that your management host can access 

(preferably on the same subnet).

NOTE:

Connections to this device must be made with shielded cables with metallic RFI/EMI connector 

hoods in order to maintain compliance with FCC Rules and Regulations.
