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

+ 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
