UCS Multihop FCoE In Under an Hour

November 19, 2012 at 10:14 am PST

It’s been a long time coming, it’s true. It was long the #1 request I have gotten when it comes to Cisco’s deployment for Fibre Channel over Ethernet (FCoE): when is UCS going to have “FCoE Northbound?”

Now, at long last, I can confirm that the answer is right now.

I saw the announcement over the weekend, and before I had a chance to even sneeze out a tweet of my own, I was beat to the punch by a few other intrepid UCS fiends. The reaction was one of unadulterated joy and pure, rapturous bliss.

Or something close to that.

In all seriousness, from a storage perspective the one thing that has driven people crazy is the fact that the UCS Fabric Interconnects (FIs) could not continue with convergence upstream. It’s been the #1 question I’ve gotten as a storage Product Manager, and while I’ve long said that FCoE is not the panacea for the Data Center, I believe this goes a long way in making converged network even more realistic in today’s environments.

Nexus 7004 – Ideal for small and space constrained data centers

With the introduction of the Cisco Nexus 7004 chassis, Cisco continues to broaden the Nexus 7000 switching deployment options for your data centers. At only 7 rack-unit (RU), the Nexus 7004 chassis provides customers with a much smaller footprint choice, while delivering configuration consistency and all the comprehensive Unified Fabric and NX-OS features of the Cisco Nexus 7000 family.

VMware’s SDN Strategy is No Threat to Cisco, says Mike Fratto

August 8, 2012 at 8:30 am PST

For those of you wondering about the impact to Cisco of Software Defined Networking and the combined SDN strategy of VMware and Nicira, I point you to a very rational and well-articulated article by Mike Fratto of Network Computing, that basically says Cisco doesn’t have much to worry about. (Enterprise Strategy Group had already said something similar, by the way).

Specifically, Fratto says:

Mike FrattoThe lack of programmability in existing networking hardware is certainly a problem, but VMware’s acquisition of Nicira does not mean that Cisco and its ilk will be marginalized… It does mean the role and management of the physical network is changing, and I think Cisco is further ahead than most of its competitors in creating a vision for the next phase of networking.

I couldn’t agree more. Since Cisco live! when we announced our Cisco ONE strategy for network programmability as well as the advances in our Nexus 1000V portfolio for virtual network overlays, I have been posting on many of the same points.

My take here was that the VMware-Nicira acquisition did not portend a strategic break with Cisco, and while there are some obvious overlaps in our product lines, there are still a number of areas of collaboration, cooperation and interoperability. The virtual network infrastructure is just one piece of a larger software stack and the differentiation will likely be decided in the orchestration, management and applications built on top of the newly programmable infrastructures sometime down the road.

Scaling the Nexus 7000 with New 2nd Generation Supervisors

Earlier this year I wrote a blog titled “Feeling the need for speed”, which highlighted the ongoing performance and port speed evolution on the Nexus 7000 platform. These and other performance enhancements on the Nexus 7000 focused on the data plane, essentially making packet switching faster. Over the last four years, we’ve increased the per slot switching capacity from 80G to 550G with the introduction of new fabric and I/O modules. If you do the math, the Nexus 7000 data plane can now support up to 17.6Tbps, that’s a lot of bits flowing through the switch.

So, to keep up with this dramatic increase in the data plane speed, we’re introducing two new supervisors, the Sup2E and the Sup2 to boost the Nexus 7000 control plane performance and scale.

In the Nexus 7000, the Supervisor is essentially the control plane. It handles all the control plane and management functions such as Layer 2 and 3 services, redundancy capabilities, configuration management, status monitoring, power and environmental management, and much more. 

To handle all these functions and be able to scale to meet the growing demands of data centers, the new supervisors are built with significantly faster CPUs and increased memory. They also offer two key new features, FCoE enablement on the F2 Series modules and VDC CPU shares, which lets you set CPU priority on a VDC basis.

The Sup2E is designed for the broadest network deployments and the highest investment protection. With daul quad-core processers and 32GB of memory, it delivers the highest performance and scale. From a pure CPU performance perspective, the Sup2E delivers 4 times the performance of the current Sup1. This increase enables faster routing and STP convergence times and increased VDC and FEX scale. With the current software release, you can configure up to 8 VDCs, plus 1 admin VDC and connect up to 48 Nexus 2000 Switches (10GE version) per Nexus 7000.

With a quad-core processer and 12GB of memory, the Sup2 is ideal for small and medium sized deployments. Even though it’s double the CPU performance compared to a Sup1, it delivers similar feature scale. However, it offers faster control plane performance and added features for the same price point as the Sup1.

Here’s a table that provides a high-level summary of the three Nexus 7000 supervisors.

 

 

 

 

 

 

 

 

 

 

So, with the introduction of the new supervisors, you’re no longer limited to a one-size fits all Supervisor selection. You can now choose the right supervisor based on the size of your network deployment and the place in the network.

For more detail on the new Supervisors, I encourage you to check out the Sup 2/2E datasheet posted on the Nexus 7000 page.
