Meet the Next Generation Fabric Extender – Cisco’s Nexus 2300 Series

More than 5 years ago, Cisco introduced its first Nexus 2000 Fabric Extender (FEX) into the market. This broad portfolio has enabled over 15,000 customers to seamlessly add network access port density across server racks without adding the inherent management complexity that comes with adding more boxes into your architecture to meet scaling requirements which ultimately translates into lower capex and opex for the business.

Today marks the next evolution for this portfolio as we introduce the Nexus 2300 platform -- the 3rd generation Fabric Extender family. Based on the extensive innovations you have come to know from the Nexus 2100 and 2200 platforms, Nexus 2300 Fabric Extenders expand on these capabilities with:

  • Larger buffers to absorb bursts of traffic for a wide variety of workloads such as multicast feeds, voice traffic, video traffic, and healthcare applications
  • Unified Ports support enabling a flexible LAN and SAN deployment through support for Ethernet, Fiber Channel and Fiber Channel over Ethernet connectivity
  • Support for Cisco’s 40G BiDi optics simplifying migration 10 to 40 Gigabit Ethernet speeds while reusing existing 10G cabling
  • Additional versatile TCAM which can be used for:
    • Advanced features such as ACL classifications and QOS
    • Hardware-capable local flow redirect for architectures that require intra-rack traffic to reduce bandwidth

Put all of these together with the single point of management, policy enforcement, zero-touch provisioning installation and automatic configuration that is available across all Nexus 2000 Fabric Extenders and you further benefit from a more simplified and flexible network design that helps you commission and decommission server racks faster, simplify operations, and support varying workload requirements.

Now let’s look at the first member of the Nexus 2300 platform, the Nexus 2348UPQ. Priced at $9500 (US List), almost the same price as current 1Gbps FEXs, the Nexus 2348UPQ supports 48 1/10 Gigabit Ethernet ports. You can add further 10 G ports when you split the 40G ports for up to 64 10G ports – perfect for data centers that are migrating their servers from 1 to 10G network connectivity. The 6 on-board 40Gbps ports support Cisco’s BiDi optics so that as you migrate from 10G to 40G as your uplink speed, you can reuse your existing 10G cabling – helping you save on the costs of re-cabling your network and get it upgraded faster! This new fabric extender can be deployed in conjunction with Nexus 5500, 5600, and 6000 parent switches and with the Nexus 7000 and 9000 Series in the future.

In summary, Cisco’s Fabric Extender portfolio has seen tremendous traction in the market as the many benefits of this architecture ultimately help create a cost-effective, flexible and simplified approach to building a data center network. The Nexus 2300 Series Fabric Extender, with the Nexus 2348UPQ, continues to deliver on these same principles and further expands on the promise of helping simplify network deployment and operations while ensuring the data center network is ready to support varying application needs. I invite you to learn more about the Nexus 2348UPQ and other Nexus 2000 Series Fabric Extenders at www.cisco.com/go/nexus2000.
