× STP stops loops, but blocks paths - reducing effective bandwidth

× Configuration Intensive (switch by switch)

× Operational complexity for configuration change and support

× Slow convergence during failure can often impact business applications and users

INTELLIGENT RESILIENT FRAMEWORK

HP Networking Meets These Challenges

Simplicity – Performance – Resiliency

IRF IS AN INNOVATIVE HP SWITCH PLATFORM VIRTUALISATION TECHNOLOGY

– Dramatically simplify the design and operations of your data centre and campus Ethernet networks

– New levels of network performance and resiliencyHP IRF overcomes the limitations of traditional Spanning Tree Protocol (STP) based and legacy competitive designs


IRF Platform Virtualization


Active link


Convergence time

User /app experience

Legend

+ Simplified/virtualised L2/L3 design and operations with a single IP and configuration file.No need for STP neither for VRRP. No MSTP design and operations headache.Switching and routing functions get virtualised as well as service modules.

+ Allows multiple active paths for scalable performance

+ Near instantaneous network recovery ensures business continuityand superior user experience

HOW IRF MEETS THIS CHALLENGE

•IRF delivers design simplicity and protocol consistency at each layer/platform

• Common platform OS and NMS further simplify configuration and support

• Active/Active 10 GbE stack and server links delivers scalable performance and highest levels of network resiliency

- Legacy vendors offers a patchwork HA and platform virtualisation options

- Technology/protocols vary based on network layer, switch type and I/O module type

- Configuration intensive design yields complexity and uncertain reliability

× 9 segments, 9 IP addresses× Any link failure will cause topology change

Only 4 segments, 3 IP addresses Link failure will not cause topology change
