5000 Series Switches are a family of low-latency, line-rate, 10 Gigabit Ethernet and
Fibre Channel over Ethernet (FCoE) switches for data center applications. The Cisco Nexus 2000 Series
Fabric Extenders extend the internal switching fabric of the Cisco Nexus switches to remote devices to
provide highly scalable, cost-effective, and simplified server-access connectivity.
The Cisco Nexus 5000 Series, part of the Cisco Nexus Family of data center–class switches, delivers an innovative
architecture that simplifies data center transformation. These switches deliver high-performance, standards-based
Ethernet and FCoE that enables the consolidation of LAN, SAN, and cluster network environments onto a single
Unified Fabric. Backed by a broad group of industry-leading complementary technology vendors, the Cisco Nexus
5000 Series is designed to meet the challenges of next-generation data centers, including dense multisocket,
multicore, virtual machine–optimized deployments, where infrastructure sprawl and increasingly demanding
workloads are commonplace.
The Cisco Nexus 2000 Series Fabric Extenders comprise a new category of data center products that provides a
universal server-access platform. Scaling across a multitude of Gigabit Ethernet, 10 Gigabit Ethernet, Unified Fabric,
rack, and blade server environments, the Cisco Nexus 2000 Series Fabric Extenders are designed to simplify data
center architecture and operations. Working in conjunction with Cisco Nexus switches, the Cisco Nexus 2000 Fabric
Extenders architecture delivers a cost-effective and efficient way to support today's Gigabit Ethernet environments
while allowing seamless migration to 10 Gigabit Ethernet, virtual machine-aware Unified Fabric technologies.
Cisco Nexus 5000 Series Hardware Features
●
The Cisco Nexus 5000 Series cut-through switching architecture supports line-rate 10 Gigabit Ethernet with
low-latency and predictable performance on all ports. These switches also support 10/1 Gigabit Ethernet
mode on a subset of the fixed ports to provide connectivity for Gigabit Ethernet attached servers and network
devices.
●
The Cisco Nexus 5000 Series supports Fibre Channel over Ethernet that enables consolidation of LAN, SAN
and cluster traffic onto a single, Unified Fabric, which greatly simplifies network infrastructure, increases
flexibility and reduces costs. By connecting to existing Fibre Channel storage arrays, FCoE protects existing
storage investments while simplifying in-rack cabling and reducing power and cooling overhead.
●
Cisco Nexus 5000 Series supports standards-based IEEE Data Center Bridging (DCB) capabilities that allows
the switches to support multiple traffic classes - LAN, SAN, and cluster - over the same link, while retaining
individual traffic treatment.
●
In addition to standard 10 Gigabit network interface cards (NICs), the Cisco Nexus 5000 Series supports
standards-based Fibre Channel over Ethernet consolidated network adapters (CNAs) that combine Ethernet
NICs and Fibre Channel host bus adapters (HBAs). These CNAs make the transition to a Unified Fabric
transparent and consistent with existing practices, management software, and operating system drivers.
●
The Cisco Nexus 5000 Series is compatible with third-party integrated transceivers and Twinax cabling
solution that delivers very low latency at a low cost, making the product line an excellent match for cluster
environments.
