The HP A5820 Switch Series features advanced flex-chassis switches that deliver a unique combination of unmatched 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE) connectivity, high-availability architecture, full Layer 2/3 dual-stack IPv4/v6, and line-rate, low-latency performance on all ports. Extensible embedded application capabilities enable these switches to integrate services into the network, consolidating devices and appliances to simplify deployment and reduce power consumption and rack space. Extremely versatile, the switches can be used in high-performance, high-density building or department cores as part of a consolidated network; for data center top-of-rack server access; or as high-performance Layer 3, 10-GbE aggregation switches in campus and data center networks.

Quality of Service (QoS)
• Powerful QoS feature: creates traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror, or remark; supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), weighted fair queuing (WFQ), weighted random early discard (WRED), weighted deficit round robin (WDRR), and SP+WDRR

Management
• Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI)

Connectivity
• High-density port connectivity: 194 10-GbE ports with a 40 Gbps resilient backplane

Performance
• Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps ensure high levels of security and ease of administration without impacting network performance

Resiliency and high availability
• Data Center Optimized Design: HP A5820AF-24XG Switch (JG219A) supports front-to-back/back to front airflow for hot/cold aisles, rear rack mounts,and redundant hot-swappable AC or DC power and fans

Manageability
• Full-featured console: provides complete control of the switch with a familiar command-line interface (CLI)

Layer 2 switching
• GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
