HA for the Aruba Core: Introducing “VSX”Design Principles
• Built for Agg & Core: availability, availability, availability
• High Availability by design during upgrades
• Flexibility for network designs: Support for active-active L2, L3 unicast and multicast
• Operational simplicity and usability for configuration
• Leverages existing and on-going investments on MC-LAG. Enables rapid feature velocity elsewhere.
• Provides virtually all the benefits of VSF except with BETTER HA.

VSX Meets our Customers Needs for High Availability
Customer requirement VSX Solution Capabilities
Redundancy“What if X breaks and Y fails?”
Resiliency“What if W sputters and Z hiccoughs?”
Performance“How long is failover? In what scenarios?”
Simplicity“How complex, with what chance for error?”
Dual Control Planes – Ideal Solution • Minimal scope of outage, each box operates separately in concert
Enhanced Link Virtualization – Ideal Solution• VSX will be improved to support L3 LAGs and remove exclusions
Support Failover and Fast Upgrades – Ideal Solution• VSX enables failover and non-stop 50% upgrades inherently
Operational Simplicity Enhancements – Good Solution• Improvements will make configuration and troubleshooting better
12
• Distributed L3 over VSX • Unified data path (active-active)• L3 ECMP + L2 VSX (highly fault tolerant)

• No spanning-tree• L2 loop-free multi-pathing (active-active)• Rapid re-convergence• Simple configuration
• Active-Active first hop gateway• No VRRP/HSRP• Simple configuration (1 command)• No gateway protocol overhead• DHCP relay redundancy
• Dual control plane for better resiliency• Unified management (synchronized
configuration and easy troubleshooting)• Independently software upgradable • In-chassis redundancy (8400) & device

Aruba OS-CX Difference: Making VSX Powerful and Easy
Database driven architecture• Allows active-active components to know the state of the peer• Enables CLI/REST/WebUI to easily expose both control planes in
a single place• Allows analytics across the redundant pair
Configuration and troubleshooting simplicity• Continuous synchronization of the common configuration• Show commands that aggregate/contrast information from both
switches for ease of troubleshooting• Almost all show commands will support “| vsx-peer” to show
information from the peer• WebUI will provide joint view of the VSX system
Hitless upgrade orchestration• Will allow proactive draining of the traffic from the switch that
undergoes upgrade
Active-Active Analytics• NAE agents will cross monitor each others database• Will detect discrepancies that remain for too long• Will validate that the overall solution is healthy

Where is the 8400 Tomorrow with VSX?
Customer requirement Solution capabilities
Redundancy“What if X breaks and Y fails?”
Resiliency“What if W sputters and Z hiccoughs?”
Performance“How long is failover? In what scenarios?”
Simplicity“How complex, with what chance for error?”
HW redundancy – management modules, fabric, power, fansSW redundancy – dual vs single control planes
Link virtualization – virtualize multiple links to one logical linkProcess resiliency – self-restart to last known good state
Low-latency link failovers – minimize duration of traffic outageFast upgrade time – minimize time-at-risk during upgrade
Easy to configure – # entities to configure, # CLI commandsLow risk of error – config sync & consistency checks
Things to be aware of when projects rise

HINTS AND TIPS
• Ask enough questions !!!!!
• Involve the Aruba Pre-Sales in an early stage !!!!!
• Which features are going to be used?
• Is it green field or rip and replace?
• Are there existing configs? If yes send them to us. We can check upfront.
• POC / test installation
• THIS IS NOT A DC SWITCH
