The Cisco UCS 6536 Fabric Interconnect (FI) is a core part of the Cisco Unified Computing System, providing both network connectivity and management capabilities for the system. The Cisco UCS 6536 Fabric Interconnect offers line-rate, low-latency, lossless 10/25/40/100 Gigabit Ethernet, Fiber Channel, NVMe over Fabric, and Fiber Channel over Ethernet (FCoE) functions.
The Cisco UCS 6536 Fabric Interconnect provides the communication backbone and management connectivity for the Cisco UCS X-Series compute nodes, UCS X9508 X-series chassis, UCS B-series blade servers, UCS 5108 B-series server chassis, and UCS C-series rack servers. All servers attached to a Cisco UCS 6536 Fabric Interconnect become part of a single, highly available management domain. In addition, by supporting a unified fabric, Cisco UCS 6536 Fabric Interconnect provides both LAN and SAN connectivity for all servers within its domain.

• Management (Cisco UCS Manager/Cisco Intersight)
  Allows all elements connected to the interconnects to participate in a single, highly available management domain.
• Unified fabric
  Decreases TCO by reducing the number of NICs, HBAs, switches, and cables required. Support Fiber Channel and Ethernet traffic concurrently in a Unified Fabric.
• Fabric extender architecture
  Scales to 20 blade chassis without adding complexity by eliminating the need for dedicated chassis management and blade switches and by reducing the number of cables needed. Provides deterministic latency for optimized application performance.
• Performance powerful
  Provides high-speed, low-latency connectivity to the chassis. Provides approximately 50 percent reduction in end-to-end system latency.
• Lossless fabric
  Provides a reliable, robust foundation for unifying LAN and SAN traffic on a single transport.
• Priority-based Flow Control (PFC)
  Simplifies management of multiple traffic flows over a single network link. Supports different classes of service, helping enable both lossless and classic Ethernet on the same fabric.
• Systemwide bandwidth management
  Helps enable consistent and coherent Quality of Service (QoS) throughout the system.
• Rear ports
  Helps keep cable lengths short and efficient.
• Redundant hot-swappable fans and power supplies
  Helps enable high availability in multiple configurations. Increases serviceability. Provides uninterrupted service during maintenance. Each fan module consists of two fan rotors. Redundancy of fan is implemented in the rotor level, with a total of 12 rotors across 6 fan modules.
