Cisco Nexus B22DELL Blade Fabric Extender


The Cisco Nexus®B22 Blade Fabric Extender is designed to simplify data center server access architecture and operations in environments in which thirdparty blade servers are used. The Cisco Nexus B22, together with the Cisco Nexus 2000 Series Fabric Extenders, Cisco®Adapter Fabric Extender (Adapter FEX), and Cisco Data Center Virtual Machine Fabric Extender (VMFEX), is part of the Cisco Fabric Extender (FEX) portfolio, which provides a highly scalable unified server access platform supporting 100 Megabit to 10 Gigabit Ethernet over fiber and copper, rack and blade form factors, and IEEE Data Center Bridging (DCB) protocol. The platform offers excellent support for the integration of thirdparty blade chassis into a Cisco Unified Fabric.

Highly Scalable, Consistent Server Access

A distributed modular system provides a scalable server access environment with no reliance on Spanning-Tree Protocol, allowing consistency between blade and rack servers.

Simplified Operations

A single point of management and policy enforcement using upstream Cisco Nexus switches eases the deployment of FEX blades through zero-touch installation and automatic configuration.

Increased Business Benefits

Reduce operating expenses (OpEx) and capital expenditures (CapEx) with:

  • Infrastructure consolidation
  • Cabling reduction
  • Feature inheritance from the parent switch, which protects current investments
