HP A5820 Switch Series
Data sheet
Product overview
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.

clients; keeps consistent timekeeping among all
clock-dependent devices within the network so that
the devices can provide diverse applications based
on the consistent time

allow high-performance remote backup and
disaster-recovery services

– IPv6 host: enables switches to be managed and
deployed at the IPv6 network's edge
– Dual stack (IPv4/IPv6): transitions from IPv4
to IPv6, supporting connectivity for both protocols
– MLD snooping: forwards IPv6 multicast traffic to
the appropriate interface
– IPv6 ACL/QoS: supports ACL and QoS for IPv6
network traffic, preventing traffic flooding
– IPv6 routing: supports IPv6 static routes and
IPv6 versions of RIP, OSPF, IS-IS, Border Gateway
Protocol (BGP) routing protocols
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
•
Unique Flex Chassis Architecture: supports the
best of both fixed chassis and modular
configurations
•
Cut-through switching: delivers wire-speed,
line-rate performance on all ports, as well as
cut-through switching for low latency
Manageability
•
Full-featured console: provides complete control
of the switch with a familiar command-line interface
(CLI)
•
Web interface: allows configuration of the switch
from any Web browser on the network
•
RMON and sFlow: provide advanced monitoring
and reporting capabilities for statistics, history,
alarms, and events
•
Multiple configuration files: allow multiple
configuration files to be stored to flash image

and distributed security enforcement that can be
managed from a central location, such as the HP
