Features and 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

•

Flexible high port density

the 5900 switch series enables you to scale your server edge with

1GbE and 10GbE ToR deployments to new heights with high-density

48-port solutions delivered in a 1RU design; the high server port

density is backed by 40GbE QSFP+ uplinks to deliver availability of

needed bandwidth for demanding applications; each 40GbE QSFP+

port can also be configured as 4 x 10GbE ports using a

40G-to-10GbE splitter cable

•

High-performance switching

cut-through and nonblocking architecture delivers industry-leading

low latency (~1 microsecond for 10GbE) for very demanding

enterprise applications; the switch delivers high-performance

switching capacity and wirespeed packet forwarding

•

Higher scalability

HP Intelligent Resilient Framework (IRF) technology simplifies the

architecture of server access networks to reduce cost and overall

complexity; up to four HP 5900 switches can be combined to deliver

unmatched scalability of virtualized access layer switches and

flatter, two-tier networks using IRF

•

Advanced modular operating system

Comware v7 software's modular design and multiple processes

bring 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 (In Services Software Upgrade)

•

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

enhanced for data center hot-cold aisle deployment with reversible

airflow—for either 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) protocol

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

support for FCoE includes expansion, fabric, trunk VF, and N ports,

and 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

Manageability

•

Full-featured console

provides complete control of the switch with a familiar CLI

•

Troubleshooting

– Ingress and egress port monitoring

enable network problem solving

– Traceroute and ping

enable testing of network connectivity

•

Multiple configuration files

allow multiple configuration files to be stored to a flash image

•

sFlow (RFC 3176)

wire-speed traffic accounting and monitoring

•

SNMP v1, v2c, and v3

facilitate centralized discovery, monitoring, and secure

management of networking devices

•

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 is provided

with sFlow and SNMP v1/v2/v3, and 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
