Nexus 2000 Series

Cisco Nexus 2000 Series Fabric Extenders logically behave like a remote line
card, and together with the Cisco Nexus parent switch it forms a distributed
modular system. The Cisco Nexus 2000 Series Fabric Extenders forwards all
traffic to the parent Cisco Nexus 5000 or 7000 Series Switch over 10 Gigabit
Ethernet uplinks. Passing all traffic to the parent switch allows traffic to be shaped
according to policies established on the parent Cisco Nexus 5000 or 7000 Series
Switch with a single point of management.
Notes Nexus 2000 Series Fabric Extenders Spotlight
Architectural flexibility
• Provides a comprehensive range of connectivity
options—100 Megabit Ethernet, Gigabit Ethernet,
and 10 Gigabit Ethernet server connectivity and
unified fabric environments—and supports copper
and fiber Gigabit Ethernet and 10 Gigabit Ethernet
connectivity options with 1GBASE-T, SFP and
SFP+, and CX1 over copper and fiber cables.
• Supports various server form factors: rack and
blade servers.
• Offers space optimized for both Top of the Rack
(ToR) and End of the Row (EoR) topologies with the
Cisco Nexus parent switch.
• Provides port-density options: 24p, 32p, and 48p.
• Enables quick expansion of network capacity.
Highly scalable server access
• Allows transparent addition of network capacity
as needed, reducing initial capital expenditures
(CapEx).
• Enables quick expansion of network capacity by
rolling in a prewired rack of servers with a ToR
fabric extender and transparent connectivity to an
upstream Cisco Nexus parent switch.
Simplified operations
• With Cisco Nexus 5000 or 7000 Series, provides
a single point of management and policy
enforcement.
• Offers plug-and-play management that includes
autoconfiguration.
• Allows smooth transition from Gigabit Ethernet to
10 Gigabit Ethernet.
• Offers innovative approach that reduces data
center cabling costs and footprint with optimized
inter-rack cabling.
Breakthrough Business Benefits
• Offers 10 Gigabit Ethernet connectivity that
provides 10 times the bandwidth for approximately
twice the price.
• Reduces cabling by up to 85 percent, power and
cooling by up to 30 percent, and CapEx by up to
40 percent.
• Supports virtual machine-aware network services;
per-virtual machine awareness helps maintain a
consistent policy view for each virtual machine
and mobility of virtual machines and workloads
within data centers.
• Supports In-Service Software Upgrade (ISSU) and
virtual PortChannel (vPC) technology, extending
the resiliency of data center deployments for
server connectivity.
