Channel group in ds4800 ds5000

 

 

Device interfaces (expansion cabinet interfaces) in ds4800 and ds5000 ):

Device Interface (expansion cabinet Interface): for example, interface 1 and interface 2 are connected through a loop switching chip in the Controller. Therefore, interface 1 and interface 2 are connected through a channel,

Control a 4---b Control 1 forms loop to 1 (loop pair)
Control a 2---b Control 3 forms loop pair 2 (loop pair)

Control a 3-B Control 1 forms a loop to 3 (loop pair)
Control a 1---b control 4 forms loop to 4 (loop pair)
...
When connecting the expansion cabinet,
First Use loop to 1, then use loop Team 2,
Use loop to 3 and loop to 4 for load balancing.
