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.

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.

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.

Layer 2 switching

• VLAN: supports up to 4,094 port-based or IEEE802.1Q-based VLANs; also supports MAC-basedVLANs, protocol-based VLANs, and IP-subnet-basedVLANs for added flexibility

Layer 3 routing

• Open shortest path first (OSPF): delivers faster convergence; uses this link-state routing Interior Gateway Protocol (IGP), which supports ECMP, NSSA, and MD5 authentication for increased security and graceful restart for faster failure recovery

Quality of Service (QoS)

• IEEE 802.1p prioritization: delivers data to devices based on the priority and type of traffic
