HP 5920 Switch Series
Fixed Port L3 Managed Ethernet Switches

Features & Benefits:

Quality of Service (QoS)

• Powerful QoS features —
  • Flexible classification — creates traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, and DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror, remark, and logging
  • Feature support — provides support for Strict Priority Queuing (SP), Weighted Fair Queuing (WFQ), Weighted Deficit Round Robin(WDRR), SP+WDRR together, configurable buffers, Explicit Congestion Notification (ECN), and Weighted Random Early Detection (WRED)

Data center optimized

• High-performance 10GbE switching — enables you to scale your server-edge 10GbE ToR deployments with 24 high-density 10GbE ports delivered in a 1RU design; delivers a 480 Gbps (357.12 Mpps) switching capacity in addition to incorporating 3.6 GB of packet buffers
• Ultra-deep packet buffering — provides up to a 3.6 GB packet buffer to reduce network congestion at the I/O that is associated with the heavy use of server virtualization, as well as bursty multimedia, storage applications, and other critical services
• Higher scalability — HP Intelligent Resilient Framework (IRF) technology simplifies the architecture of server access networks; up to four HP 5920 switches can be combined to deliver unmatched scalability of virtualized access layer switches and flatter, two-tier FlexFabric networks using IRF, which reduces cost and complexity
• Advanced modular operating system — Comware v7 software's modular design and multiple processes deliver native high stability, independent process monitoring, and restart; the OS also allows individual software modules to be upgraded for higher availability and supports enhanced serviceability functions like hitless software upgrades with single-chassis ISSU
• TRILL and EVB/VEPA — Transparent Interconnection of Lots of Links (TRILL) is supported to increase the scale of enterprise data centers; EVB/VEPA provides connectivity into the virtual environment for a data center-ready environment
• Reversible airflow — switches are enhanced for data center hot/cold aisle deployments with reversible front-to-back or back-to-front airflow
• Redundant fans and power supplies — 1+1 internal redundant and hot-pluggable power supplies and dual fan trays enhance reliability and availability
• Lower OPEX and greener data center — provide reversible airflow and advanced chassis power management
• Data Center Bridging (DCB) protocols — supports IEEE 802.1Qbb Priority Flow Control (PFC), Data Center Bridging Exchange (DCBX), and IEEE 802.1Qaz Enhanced Transmission Selection (ETS) for converged applications
• FCoE support — provides support for FCoE, including expansion, fabric, trunk VF and N ports, aggregation of E-port, N-port virtualization; fabric services such as name server, registered state change notification, and login services; per-VSAN fabric services, FSPF, soft and hard zoning, Fibre Channel traceroute, ping, debugging, and FIP snooping
• Jumbo frames — with frame sizes of up to 10,000 bytes on Gigabit Ethernet and 10-Gigabit ports, high-performance remote backup and disaster-recovery services can be enabled

Management

• IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — advertises and receives management information from adjacent devices on a network, facilitating easy mapping by network management applications
• SNMPv1, v2c, and v3 — facilitate centralized discovery, monitoring, and secure management of networking devices
• Port mirroring — enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
• Out-of-band interface — isolates management traffic from user data plane traffic for complete isolation and total reachability, no matter what happens in the data plane
• Remote configuration and management — is available through a secure command-line interface (CLI) over Telnet and SSH; Role-Based Access Control (RBAC) provides multiple levels of access; Configuration Rollback and multiple configurations on the flash provide ease of operation; remote visibility with sFlow and SNMP v1/v2/v3 is fully supported in HP Intelligent Management Center (IMC)
• ISSU and hot patching — provides hitless software upgrades with single-unit In Services Software Upgrade (ISSU) and hitless patching of modular OS
• Autoconfiguration — provides automatic configuration via DHCP autoconfiguration
• Network Time Protocol (NTP) and Secure Network Time Protocol (SNTP) — synchronizes timekeeping among distributed time servers and 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

Resiliency and high availability

• Intelligent Resilient Framework (IRF) — HP IRF technology enables an HP FlexFabric to deliver resilient, scalable, and secured data center networks for physical and virtualized environments; up to four 5920 switches can be grouped together in an IRF configuration, which allows them to be configured and managed as a single switch with a single IP address; this simplifies ToR deployment and management, reducing data center deployment and operating expenses

Layer 2 switching

• Address Resolution Protocols (ARP) — supports static, dynamic, and reverse ARP and ARP proxy
• Flow Control — IEEE 802.3x Flow Control provides intelligent congestion management via PAUSE frames
• Ethernet Link Aggregation — IEEE 802.3ad Link Aggregation of up to 128 groups of 16 ports; support for LACP, LACP Local Forwarding First, and LACP Short-time provide a fast, resilient environment that is ideal for the data center
• Spanning Tree Protocol (STP) — STP (IEEE 802.1D), Rapid STP (RSTP, IEEE 802.1w), and Multiple STP (MSTP, IEEE 802.1s) provide loop avoidance
• VLAN support — provides support for 4,096 VLANs based on port, MAC address, IPv4 subnet, protocol, and guest VLAN; supports VLAN mapping
• IGMP support — provides support for IGMP Snooping, Fast-Leave, Group-Policy, and IPv6; IGMP Snooping provides Layer 2 optimization of multicast traffic
• DHCP support at Layer 2 — provides full DHCP Snooping support, including DHCP Snooping Option 82, DHCP Relay Option 82, DHCP Snooping Trust, and DHCP Snooping Item Backup

Layer 3 services

• Address Resolution Protocol (ARP) — determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
• Operations, administration and maintenance (OAM) support — provides support for Connectivity Fault Management (IEEE 802.1AG) and Ethernet in the First Mile (IEEE 802.3AH); provides additional monitoring that can be used for fast fault detection and recovery

Layer 3 routing

• Virtual Router Redundancy Protocol (VRRP) and VRRP Extended — allow quick failover of router ports
• Policy-based routing — makes routing decisions based on policies set by the network administrator
• Equal-Cost Multipath (ECMP) — enables multiple equal-cost links in a routing environment to increase link redundancy and scale bandwidth
• Layer 3 IPv4 routing — provides routing of IPv4 at media speed; supports static routes, RIP and RIPv2, OSPF, BGP, and IS-IS
• Layer 3 IPv6 routing — provides routing of IPv6 at media speed; supports RIPng, OSPFv3, BGP4+ for IPv6, and IS-ISv6
