applications and processes. If a process abnormally exits, the watchdog process automatically
restarts the process.
Backup and Recovery Capabilities
When Linux is used, the system provides the backup and recovery capabilities to full backup
and restore eSpace EMS files and database data. This ensures the reliability of the system and
database data.
Security Hardening Capability
Security of the system host is reinforced to ensure safe and stable running of the operating
system. Therefore, system services can run safely and stably.
The eSpace EMS server has the following security risks:
A large number of services and ports are opened during operating system installation,
which leaves the system vulnerable to malicious attacks.
No strict restrictions are imposed on the file rights and environment variables, which
increases security vulnerabilities of the system.
To achieve security hardening, you can add, modify, or tailor the modules and components of
the system, and shield and eliminate the defects and security vulnerabilities of the system.
Geographical Redundancy Capability
To ensure service continuity, establish the same service system of the PM in the RM. The PM
synchronizes data to the RM periodically. When a disaster such as fire or earthquake occurs in
the PM, services can be switched to the RM. This is called geographical redundancy.
Generally, the PM provides services. When a disaster occurs in the PM, the eSpace EMS
service can be switched manually to the RM, which reduces the service interruption duration.
When Linux is used, the eSpace EMS provides GDR to support geographical redundancy.

One IP phone or SBC is equal to one equivalent NE, one IAD, GS8 or EGW is equal to five
equivalent NEs, and one IP PBX is equal to 50 equivalent NEs.
The equivalent NEs managed by the eSpace EMS are calculated in the following formula: IP PBX x
50 + (IAD + GS8 + EGW) x 5 + IP Phone + SBC. The total number cannot exceed the maximum
number of topology nodes allowed.
