The HP FlexFabric 11900 Switch Series is a high-performance modular core switch designed for medium to enterprise data centers and as a medium core switch for larger enterprises. The FlexFabric 11900 sets a benchmark for performance, reliability, and scalability with CLOS architecture and 3-microsecond latency, delivering ultra-high 1/10/40GbE port density that is 100GbE-ready.

With HP IRF technology, the HP FlexFabric 11900 Switch Series can be virtualized across four chassis with a single management interface—enabling flatter, more agile networks.

High Performance and Low Latency Data Center Networking

- The HP 11900 FlexFabric Switch Series provides a high-speed fully distributed next generation CLOS architecture with up to 7.7 Tb/s switching capacity and forwarding capacity of up 5.7 billion packets per second.
- 100GbE ready with ultra-high 10/40GbE port density and 3-microsecond latency.
- HP Intelligent Resilient Fabric (IRF) allows up to four 11900 Switch Series chassis to be virtualized into a single IRF fabric that can be managed as a single device with one IP address.
- Broad data center feature set with no hidden costs for future networking OS features, with advanced Comware 7 OS supporting L2/L3, Dual stack IPv4/IPv6, DCB, FCoE, TRILL, VEPA and more.

Optimized Architecture for Cloud-Connected Enterprise Data Centers

- The HP 11900 FlexFabric Switch Series includes a high-speed fully distributed next generation CLOS architecture that simplifies large-scale switching architecture, reduces possible fault points, and provides greater availability.
- HP Comware 7, an enterprise grade advanced modular operating system, brings native high stability, independent process monitoring, and modular design to easily restart processes for seamless software upgrades, enhancing serviceability and greater high-availability.
- Fast software upgrades without service interruptions for higher availability and zero packet loss with In-Service Software Upgrade (ISSU).

Single Management View of the Network

- The HP FlexFabric 11900 Switch Series can be seamlessly managed with HP Intelligent Management Center (IMC) to provide end-to-end network transparency with consistent network experience through comprehensive configuration, compliance and policy management.
- IMC unifies management of virtual and physical networks by taking advantage of the VEPA support built into the HP 5900 top-of-rack switches.
