PSA Peugeot Citroën Uses H3C Switches to Improve Office Automation and Deploy New Services

About PSA
France's PSA Peugeot Citroën (PSA) is a leading global automaker which sells cars and trucks in over 150 countries around the world. Its operations include global industrial locations comprising 15 automobile assembly plants and 15 components and casting plants (for engines, gearboxes, suspensions).

Challenge
Recently, the company constructed a new office facility named "P le Tertiaire 2" (PT2) near its manufacturing plant in Poissy, a suburb of Paris. The building will house offices and various operational departments. As a brand new structure, PSA had the opportunity to build a sophisticated, feature-rich network for PT2 from the ground up. PSA wanted a complete office automation capable network that supports VoIP and data applications. When selecting a vendor, PSA rated potential providers on their quality of service, performance and expandability of the solution. After evaluating many vendors, PSA chose H3C to design and build the network for its PT2 building.

Our Solution For PSA
Following the requirements set out by PSA, H3C designed a network architecture based on its portfolio of high performance switches. Starting at the core, two S8500 (H3C S9500) series switches were used as core layer switches to prevent single point faults. The S8500 (H3C S9500) switches are connected via double Gigabit Ethernet trunks offering redundant backup. One S8500 (H3C S9500) switch also connects PT2 to a PSA data center.
Sixteen S6500 (H3C S7500) series switches were used as aggregation and access layer switches. To maximize the efficiency of the S6500 (H3C S7500) series switches, the network design features GE-to-desktop connections, eliminating the need for a separate access layer. And every S6500 (H3C S7500) switch is connected to both the core layer switches by double GE links for maximum redundancy.

Benefit
PSA Peugeot Citroën's new office facility, PT2, is equipped with a dependable, high speed OA network that enables the company to deploy integrated VoIP and data services in a single network architecture. The new PT2 building-wide network boasts outstanding performance with a switch fabric capacity of 300Gbps and a L3 packet throughput of 180Mpps. Double links between switches and H3C's fault-tolerance technology provide complete redundancy. The expansible nature of the H3C S8500 (H3C S9500) and S6500 (H3C S7500) switches also helps give PSA a future-proof IT investment.
