High TCO
Capacity ExpansionCapacity Expansion2 31 4
Modular capacity expansion by reusing existing network resources cannot be performed. The existing EMS have to be replaced when reach the capacity bottleneck of single-server.The process of cross-servers load balancing is complex. In this case, Carriers generally need to buy new servers. The investment cost increases.
Maintenance Maintenance
The separate maintenance mode reduces the efficiency of operation and maintenance (O&M) and increases the investment on human resource (HR). The O&M cost increases continuallycontinually.
Disaster Tolerance Disaster Tolerance
Disaster tolerance can only be performed in the 1:1 mode on the single-server EMS. This increases the cost of investment on the hardware, maintenance ,power consumption.
