NX-OS EnhancementsOptimized for Fabric• Modern: 64-bit Linux 3.4.10 Kernel
• Comprehensive Purpose Built DC Feature Set: L2/L3/VXLAN, ISSU, Patching* (Cold, Hot), Online Diagnostics (GOLD) etc.
• Trimmed base image: (approximately 50%) and single binary image - common image across all platforms for deployed mode
• Fault Containment: Complete process isolation for both features & services
• Resiliency: Restartable user-space network stack & driver, stateful restart of processes – no switch reboot etc.
• Open Management and Programmable Infrastructure: CLI, SNMP, NetConf/XML, OnePK, Open Containers, JSON etc.

Many customers spend extensive time and effort to test and qualify software prior to deployment. In today’s environments, if a defect is found, effectively root-caused, and integrated, since it is rolled out through a maintenance release, customers would need to restart their qualification cycle, wasting time, and pushing out deployment dates…

The Nexus9000 Standalone platforms introduces new patching capabilities that allows specific defects to be rolled out in an independent package that can be applied to existing base software binaries. This will help reduce customer code certification times, leading to greater customer satisfaction…

NX-OS EnhancementsConsistency Checkers
• To effectively scale, a distributed management approach is optimal.• In distributed systems, maintaining consistency between resources is key to
scaling safely.
• Why is my traffic not going through this path... • My routing table looks good .. How do I debug

In Summary• The Nexus 9500 Chassis provides scalable performance
with consistent parts across the Nexus9504, 9508, 9516 platforms.
• The platform is future proofed for higher power ASICs.
• The Nexus 9500 has no mid-plane to further improve front-to-back airflow.
• The Merchant+ strategy minimizes the number of ASICs and lowers power consumption while providing value-added network options.
• The QSFP BiDi optics allow 40Gb connectivity over standard OM3/OM4 cable plants.
