Cisco UCS 6536 Fabric Interconnect

The Cisco UCS 6536 36-Port Fabric Interconnect is a One-Rack-Unit (1RU) 10/25/40/100 Gigabit Ethernet, FCoE, and Fibre Channel switch offering up to 7.42 Tbps throughput and up to 36 ports. The switch has 32 40/100-Gbps Ethernet ports and 4 unified ports that can support 40/100-Gbps Ethernet ports or 16 Fiber Channel ports after break-out at 8/16/32-Gbps FC speeds. The 16 FC ports after breakout can either operate as an FC uplink port or as an FC storage port. The switch supports 2 1-Gbps speed after breakout and all 36 ports can breakout for 10/25-Gbps Ethernet connectivity. All Ethernet ports are capable of supporting FCoE.

The Cisco UCS 6536 Fabric Interconnect also has one network management port, one console port for setting the initial configuration, and one USB port for saving or loading configurations. The FI also includes L1/L2 ports for connecting two fabric interconnects for high availability

The Cisco 6536 Fabric Interconnects are a core part of the Cisco Unified Computing System, providing both network connectivity and management capabilities for the system. The Cisco 6536 offer line-rate, low-latency, lossless 10/25/40/100 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE), and Fibre Channel functions.

The Cisco UCS 6536 Fabric Interconnect provide the management and communication backbone 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 the LAN and SAN connectivity for all servers within its domain.

Capability/Feature Cisco UCS 6536 (36 Ports)
Chassis 1RU 36-port Fabric Interconnect
Throughput 7.42 Tbps switching performance

Management by Cisco Intersight Allows all elements connected to the interconnects to participate in a single, highly available management domain
Unified Fabric
  • Decreases total cost of ownership (TCO) by reducing the number of NICs, HBAs, switches, and cables needed
  • Support Fibre Channel and Ethernet traffic concurrently in a Unified Fabric
  • Increases flexibility with a range of interconnect solutions, including copper Twinax cable for short runs and fiber for long runs
  • Consumes less power per port than traditional solution
Fabric Extender Architecture
  • Scales to 20 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
QSFP28-compatible Ports Allows all ports to be configured to operate in 40/100 Gigabit Ethernet mode with the transceiver options specified for use with QSFP28-compatible ports
Transceivers The Cisco UCS 6536 series FIs support a wide variety of 10/25/40/100 Gigabit Ethernet connectivity options using Cisco 10/25/40/100 Gbps modules. Unified Ports (UP) on the Cisco UCS 6536 support 10/25/40G/100G Gigabit Ethernet connectivity or a 128G FC-QSFP28 which can breakout into four 8/16/32 Gigabit Fibre Channel connection. Cisco UCS 6536 provides flexible uplink port connectivity at 1G/10G/25G/40G/100G via Gigabit Ethernet transceivers and cables. Table 3 lists the supported transceiver options.
Front-to-Back Cooling Fan side intake, port side exhaust
Redundant hot-swappable fans and power supplies
  • Helps enable high availability in multiple configurations
  • Increases serviceability
  • Provides uninterrupted service during maintenance
Rear Ports Helps keep cable lengths short and efficient
Performance
  • Provides high-speed, low-latency connectivity to the chassis
  • Provides approximately 50% reduction in end-to-end system latency (latency is less than 1 microseconds)
Lossless Fabric Provides a reliable, robust foundation for unifying LAN and SAN traffic on a single transport
Priority 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
