The M2000 SLS system is composed of N+1 servers, including 1 master server, N-1 slave servers, and 1 standby server. It is also called "N:1 solution".
The master server provides public management services, the slave servers providefeature management services such as performance management andconfiguration management, and the standby server acts as the redundancy of themaster and slave servers.
Master/standby switchover or slave/standby switchover can be implemented inthe entire system through cluster monitoring (VCS).

Master server and slave servers: Each server of the M2000 SLS system is aprocessing node, and each server needs to run the M2000 server software and
the database software. Standby server: When the master server or any slave server is faulty, services can
be switched to the standby server.
Disk arrays: Disk arrays are used for storing data. The master server and eachslave server is configured with a disk array, respectively.
Optical switches: Optical switches connect disk arrays to servers through opticalfiber.
M2000 client: The M2000 client refers to a PC running the M2000 client software.

Consists of multiple servers for running services, and provides the managementcapacity for super large networks
Has the capacity to centrally manage the entire network as a logical set of EMS(element management system)
Supports the uniform northbound interface, and thus reduces the maintenancecost
Monitors and manages the servers through the cluster software, and improvesthe availability of software and hardware by automatically discovering softwareand hardware faults
Supports the master/standby switchover and slave/standby switchover, and thusimproves the availability of element management services
Supports smooth network expansion (without affecting the existing services) byconnecting new NEs to new slave servers

The M2000 SLS system supports manual switchover and automatic failover.
When operating and maintaining the master or a slave server, users can manually
switch the services to the standby server.
The duration of service interruption is shortened when users manually switch theservices to the standby server before operating and maintaining the originalmaster or slave server.
When any of the following faults occurs on the master server or a slave server,the system performs a failover to switch services to the standby server.
CPU fault
Memory fault
Disk access failure
Fault on the main board Communication disconnection between the host Ethernet adapter and the
LAN switch
Fault on the operating system
Database fault
The M2000 server application is faulty and cannot be rectified.
If the following faults occur on the network, no failover is triggered.
Single Ethernet port or Ethernet cable disconnection
Single heartbeat cable disconnection
Single Ethernet switch fault
Single disk fault in the disk array

M2000 server software is composed of multiple functional modules. The modulescommunicate with each other and communicate with the relevant modules on M2000
clients through the CORBA software bus. M2000 server software provides interfacesconnecting to the NMS through the NMI module, and provides interfaces connecting tothe adaptation software of various NEs through the public adaptation module.
In addition, some modules access the databases on the M2000 servers and makedatabase operations through the database interfaces. Only the M2000 server managingthe UMTS and GSM networks have software management, network monitoring, andresource monitoring modules.

In the network management, the M2000 server must process the following data:performance measurement data, alarm data, configuration data, network element
(NE) logs, NE software and patches, and NE backup data. Among these data, the performance data, accounting for 80% of the total, is the
key element for determining the data processing capability of the system.
