Cisco Nexus Networking
Scalable, consistent server access
The Cisco Nexus® B22DELL Fabric Extenders behave as remote line cards for a parent Cisco Nexus® 5000 switch. The Fabric Extenders are essentially extensions of the parent Cisco Nexus switch fabric, with the Fabric Extenders and the parent Cisco Nexus switch together forming a distributed modular system.

Simplified operations
Ease the commissioning and decommissioning of blades through a single point of management, zero-touch installation and automatic configuration of fabric extenders. Implement upstream policy enforcement with Cisco Nexus switches.
Cisco Nexus Networking
Reduced power and cooling
Ensure optimal cabling, device consolidation and efficient bandwidth utilization with the M1000e Blade System for a significant reduction in data center power and cooling needs.

Increased business benefits
The Cisco Nexus B22DELL Fabric Extender is an excellent platform for migration from 1GbE to 10GbE. Scalable 10GbE provides 10 times the bandwith for only about double the cost of GbE.

Cost-effective consolidation and migration
Help protect your investment into the future by providing an easy migration path to low-latency 10GbE, high-performance computing (HPC) and virtual machine-aware networks.
