5.3 Steps to connect host
1. Confirm there's an SFP module inserted in host channel, and plug off black plastic plug on
SFP.
2. As for FC host channel, insert one end of fiber-optic cable into SFP interface of host
channel.
3. Insert the other end of the cable into corresponding host FC HBA card/network card or
switch, and guarantee the rate matches with protocol.
4. It is suggested to label both ends of the cable, which is very important for you when
disconnect the cable and carry out operation on controller.
Suggested label content includes: Hostname and HBA card ports, controller ID (i.e. controller A),
host channel ID (i.e. host channel 1).
Label writing example: i.e. a cable is used to connect No. 1 port in No. 1 HBA card of a host
named Heng with No. 1 host channel of controller A, and label could be abbreviated according to
the following: Heng-HBA1/P1,CtA-Hch1
5. Repeat these steps to connect all host channels to be used.
5.4 Host channel connection topology
5.4.1 Direct connection topology
One host is directly connected to a dual-controller disk array.
5.4.2 Switch connection topology
Two hosts are connected to dual-controller storage disk array via switch.
