All You Need to Know About the Cisco UCS 6332 Fabric Interconnect

by Darin Knobbe, on Aug 20, 2020 1:45:00 PM

The Unified Computing System (UCS) Fabric Interconnect (FI) is a core part of the design to improve scalability and reduce the total cost of ownership of data centers. Through integrating all components into a single platform, the system acts as a single unit which simplifies management. Cisco UCS Architecture provides a range of products including a UCS VIC (virtual interface card), UCS Blade Server Chassis, UCS FEX (Fabric Extenders), Blade Chassis FEX, Rack Mount FEX, B-Series Blade Servers, C-Series Rack Servers, and more. The fundamental difference Cisco UCS is the servers are connected to the Fabric Interconnects, then the FI is connected to the network switches. The devices are usually installed as head units at the top of server racks, in which all the server components are attached to the fabric interconnect. Today we'll dive into the UCS FI 6332 and how it can find its way to the top of rack in your data centers.

A Quick Look into the Fabric Interconnect

Each Fabric Interconnect is typically configured as a highly available clustered pair in production environments and provide active-active data traffic. By deploying in pairs, each server or blade chassis is connected to both Fabric Interconnects to protect against FI failure. Fabric Interconnects provide two capabilities:

  • Network Connectivity to both LAN and SAN
  • UCS infrastructure management through embedded management software UCSM for both hardware and software management

Cisco has introduced a new series of Fabric Interconnects, the 6300 series with Gen 3 UCS hardware. The framework incorporates a low-inertness, lossless a 10 and 40 Gigabit Ethernet bound together system texture with big business class, x86-engineering workers. The framework is an incorporated, versatile, multi skeleton stage in which all assets take an interest in a brought together administration space. The core functionality is the same in all generations, with a difference in number of physical ports, and can be upgraded to the latest UCSM software. Of these physical ports, the Fabric Interconnects are converged meaning the physical SFP and FI software configuration determines whether each port can be configured as an Ethernet port, an FCoE, or an FC port.

Why You Should Have the 6332 at the Top of Your Rack

The Cisco UCS Fabric Interconnect can boil down to one job, connecting your UCS Servers to your network. With each unique IP address, each Fabric Interconnect logs into the Cisco UCS Manager. When configuring, you can add variety to the ports, for example:

  • Universal Ports - Operate as Ethernet or Fibre Channel ports
  • Ethernet Ports - For Ethernet or FCoE connectivity
  • Uplink Ports - for uplink to the Cisco Nexus Infrastructure

Cisco's UCS Manager allows all elements connected to the interconnects to participate in a single, highly available management domain. Through the unified fabric a lower total cost of ownership can be achieved by reducing the number of NICs, HBAs, switches, and cables required to operate the interconnect. Transparently, the unified fabric encapsulates Fiber Channel packets into Ethernet. The Fabric Extender architecture scales to 20 blade chassis without adding complexity by eliminating the need for dedicated chassis management and blade switch. By ultimately reducing the number of cables needed, management simplifies and the architecture provides deterministic latency for optimized application performance.
