Introducing Cisco Nexus 3100 Top of Rack Data Center Switches

Cisco always strives to innovate while meeting customer needs. Today we are proud to unveil the  Cisco Nexus 3100 line of switches as part of our Unified Fabric Data Center portfolio. These highly scalable, power efficient, and flexible switches feature significant improvements in port density, programmability and VXLAN capable gateway functionality that are ideal for data center top-of-rack (ToR) deployment scenarios. As the second generation Nexus 3000 series, they offer a balanced mix of performance, cost, simplicity, and an innovative feature set that complements the rest of Cisco’s overall top-of-rack solutions.

A First Glimpse…

As the below graphic indicates, both switches are 1RU in height with 32 line rate 40-Gbps Quad Small Form-Factor Pluggable (QSFP+) ports for the Nexus 3132Q and 48 line rate 10 Gbps SFP+ with 6 fixed QSFP+ ports for the Nexus 3172PQ. All of the QSFP+ ports on the device can operate as a  native 40-Gbps port or a four independent  10-Gbps ports. The switches also have a serial console port, USB port, PPS connector and an out-of-band 10/100/1000-Mbps Ethernet management ports. From a software perspective, the rich NX-OS operating system fully supports the Cisco Open Network Environment framework with Openflow and the onePK toolkit in addition to standards based Layer 2 and Layer 3 features.

Celebrating 5 Year Anniversary of Cisco Nexus 1000V Launch

August 16, 2013 at 5:00 am PST

Today marks an important milestone for one of our most strategic data center products and the foundation of virtual networking portfolio. Five years ago, the Nexus 1000V virtual switch was the pioneer in the virtual networking market with its launch at VMworld in 2008. Since then it has been adopted by over 8000 customers and continues to grow on other platforms, such as Microsoft Hyper-V, and soon Linux/KVM. Today, Nexus 1000V represents the largest software controller-based networking solution (aka, Software Defined Networking or SDN) in the industry.

We continue to add hundreds of paying customers every quarter, in spite of offering a fully featured no-cost essential edition.   The interest in the virtual networking space also continues to increase ever since the SDN trend started.  There are also plenty of FUD or rumors being spread about the Cisco’s virtual networking solution.  On this 5th year anniversary, let’s do some myth busting focused on Nexus 1000V based solutions.

Nexus 1000V Winning Multiple Awards; VXLAN Scaling with BGP and More on Display at Cisco live!

June 24, 2013 at 4:00 am PST

Cisco Live Orlando EntranceCisco live is here and the news and awards around the Nexus 1000V cloud networking and services platform just keep rolling in. Last week we announced the Citrix NetScaler 1000V virtual application delivery controller, which will be sold by Cisco. The Microsoft Hyper-V version of Nexus 1000V was officially released this month, and just like its VMware vSphere companion, there is a free version users can download and deploy. On the heels of its release the Nexus 1000V for Microsoft Hyper-V won the Best of Show in the virtualization category at Microsoft’s Tech Ed Conference.

Best of InteropAwards just kept piling up for the broader portfolio as Nexus 1000V InterCloud, our secure hybrid cloud connectivity solution, won a Best of Interop award in Tokyo this month. And just to show the marketing team is pulling its weight, a Nexus 1000V InterCloud video won a prestigious Silver Communicator award in the Online video/ B2B category.

There’s lots of new stuff to talk about Cisco live as well. If you recall, in February I discussed enhancements that Cisco was making in the Nexus 1000V portfolio to eliminate the requirement in VXLAN for IP Multicast. [Those enhancements are now shipping in a new Nexus 1000V release 2.2, full code string 4.2(1)SV2(2.1).] This new version even supports virtual switching for up to 128 hosts and 4096 virtual ports for greater scalability.

Lippis Podcast on All Things Great and New with VXLAN

May 31, 2013 at 1:08 pm PST

Han Yang PodcastThis week Nick Lippis from the Lippis Report sat down with Cisco Nexus 1000V Product Manager, Han Yang, to talk about the latest enhancements and trends with VXLAN, the primary virtual overlay tunneling technology in Cisco Nexus 1000V virtual networks.

In this 15 minute podcast (registration required), Han touches on three key innovations in the VXLAN area: 1) Cisco approaches to eliminating the requirement for IP Multicast by VXLAN (which I earlier blogged about here), 2) the support for virtual services, like virtual firewalls, with vPath (which I blogged about here), and 3) the use and availability of VXLAN gateways to connect virtual workloads to physical workloads in mixed application environments (which I haven’t blogged about yet, but probably should have :-)).

Nick’s podcasts always provide a good perspective on emerging technology trends and he takes complex topics and really helps his listeners get up to speed on the important bits. We always enjoy the chance to work with him. Give it a listen and let us know what you think.
