BCM56820LB0KFSBLG

BCM56820 Brief ® 24 X 10-GBE + 4 X 1-GBE MULTILAYER ETHERNET SWITCH SUMMARY OF BENEFITS FEATURES • Provides 24 10-Gigabit Ethernet (10-GbE) ports + four 1-GbE • High level of integration and low power consumption enable • Line rate full-duplex switching for 240+ Gbps. • Intelligent Traffic Management with SAFC supports storage, ports; each of the 10-GbE ports can also support 1 GbE, 2.5 GbE, or 10 GbE, as well as HiGig™/HiGig2™ protocols. • Built-in Layer 2 (L2), VLAN, and Layer 3 (L3) tables with 10 Quality of Service (QoS) queues per port. • Multistage ingress and egress ContentAware™ Engine for deep packet inspection and classification provides flexible ingress and egress Access Control Lists (ACL), IPv4/v6 µflow, proprietary headers, and multi-tuple lookups, all at line rate. • IPv4 and IPv6 Virtual Routing with full support for L2/L3 tunnels (Generic Routing Encapsulation [GRE], IPv4 over IPv6, IPv6 over IPv4, Queue in Queue [QinQ], 802.1ah) • Intelligent scheduler supports Strict Priority (SP), Weighted Round Robin (WRR), and Deficit Round Robin (DRR) with builtin Weighted Random Early Discard (WRED) and Explicit Congestion Notification (ECN) for congestion avoidance. • IEEE 802.3™ Link Pause and Service Aware Flow Control™ high-performance, high-port density 10-GbE in the same form factor as 1-GbE solutions. HPC, video, voice, and data over unified 10-GbE fabric enabling convergence in the data center. • L o w p o w e r , s up e r i o r E nt e r p r i s e c l a s s f e a t ur e s , a nd industry-leading 10-GbE port density empower next-generation Enterprise aggregation and data center applications. • Advanced load balancing, fast hardware failover and recovery (< 10 μs), and ultralow latency (< 1 μs) provide high performance, scalable, and reliable solutions for High Performance Computing (HPC) environments. • Robust integrated SerDes, on-chip packet buffer memory, and PLLs accelerate system design and drastically reduce cost and conserve board space. • Sixth-generation HiGig/HiGig2 stacking technology facilitates full-speed upgrade while maintaining compatibility with existing deployed switches. (SAFC) mechanism allows in-band backpressure per Class of Service (CoS). • Fully compatible Broadcom software API and Software • Full support for tricolor marking and metering with policing on Development Kit (SDK) enable software reuse from existing deployed systems and faster time-to-market. ingress and egress separately (RFC-2698 and MEF).
