RATP chooses Bull and its SafeKit software for the centralized control room on Line 1 of the Paris Metro.

Posted on 15 March 2013 by Pierre Picard

Bull Evidian’s SafeKit software will improve the operation of ‘critical’ applications that are vital to the business and cannot, therefore, be subject to even the slightest downtime. The solution has the additional advantage that it runs on systems that are already in place.

As part of the program to automate Line 1 of the Paris Metro, which carries some 725,000 passengers a day, RATP has chosen the SafeKit solution from Bull Evidian.

The management of the centralized control room for Line 1 is a ‘critical’ application: even in the case of an IT failure, the control room operators still have to have access to information about and images of the network in order to ensure service continuity and guarantee passenger safety.

This is why RATP has opted for a high technology solution featuring:

-       High availability: providing guaranteed 24×7 supervision, thanks to back-up servers that are ready to take over, immediately, at all times

-       Load balancing: the application must be able to support a very large number of simultaneous connections

-       ‘IT failure resistance’: not all the servers are housed in the same place, which helps protect against fire or flooding, for example.

SafeKit is one of the only products available worldwide that combines load balancing and automatic failover after an incident with real-time data replication (for high availability and disaster resilience).

“Automating Line 1 of the Paris Metro is a major project for RATP, required a centralized control room designed to resist IT failures. SafeKit – a purely software solution – delivers the three key functions we need: load balancing between servers, automatic failover after an incident and real-time data replication.  It was very simple to split our

servers across remote machine rooms,” says Stéphane Guilmin, Project Manager at RATP.

The Centralized Control Room (CCR) of a subway line is a hub of critical activity. The operators managing the line must react immediately to the slightest incident. The idea of an IT failure compromising the operators’ view of the line’s activity is totally unthinkable. More than 20 SafeKit clusters running under Windows and Linux are in operation on this project,” explains Bruno Rochat, SafeKit Product Manager at Bull Evidian. “Thanks to Bull’s expertise in mission-critical systems, this highly innovative product has been developed and is being marketed to address this type of challenge.”
