Reliability
The CX600-X8 has three SFUs. Two SFUs are integrated on two SRUs. The other SFU is
separate. These three SFUs work in 2+1 load balancing mode. The three SFUs load balance
services at the same time. When one SFU is faulty or being replaced, the other two SFUs
automatically take over its tasks to ensure normal delivery of services, improving system
reliability.
