Cloud computing is part of the journey to deliver IT as a Service which enables IT to change from a cost center to a business strategic partner. Forrester Research recently published a report that concluded, “Cloud computing is ready for the enterprise… but many enterprises aren’t ready for the cloud.”1 Yet Cloud deployments are happening – and I mean all types of Clouds – Private, Public and Hybrid. In other words, we have entered the World of Many Clouds.
Network touches everything and is a key building block for agile and scalable virtualized and Cloud-based data centers. Yesterday, I have introduced our new Nexus 6000 series and new 40 GE extensions to Nexus 5500 and 2000 Series. Today, I would like to introduce the very first services module for the Nexus 7000 Series.
Consider these impressive stats shared in a keynote from Cisco’s CTO and CSO Padmasree Warrior last week at Cisco Live, London:
50 Billion “things” including trees, vehicles, traffic signals, devices and what not will be connected together by 2020 (vs. 1000 devices connected in 1984)
2012 created more information than the past 5000 years combined!
2/3rd of the world’s mobile data will be video by 2015.
These statistics may seem a bit surprising, but the fact is, they cannot be ignored by CIOs and others chartered with the responsibility of managing IT infrastructure.
Impact on Enterprise and SP Infrastructure strategies
Further, these trends are not silo’d and are certainly not happening in a vacuum. For example, Bring-your-Own Device (BYOD) and the exponential growth of video endpoints, may be happening in the “access”, but they are causing a ripple effect upstream in the data center and cloud environments, and coupled with new application requirements, are triggering CIOs across larger Enterprise and Service Providers to rapidly evolve their IT infrastructure strategies.
It is much the same with cloud infrastructure strategies. Even as Enterprises have aggressively adopted the journey to Private Cloud, their preference for hybrid clouds, where they can enjoy the “best of both worlds” – public and private have grown as well. However, the move to hybrid clouds has been somewhat hampered by challenges as outlined in my previous blog: Lowering barriers to hybrid cloud adoption – challenges and opportunities.
The Fabric approach
To address many of these issues, Cisco has long advocated the concept of a holistic data center fabric, heart of its Unified Data Center philosophy. The fundamental premise of breaking silos, and bringing together disparate technology silos across network, compute and storage is what makes this so compelling. At the heart of it, is the Cisco Unified Fabric, serving as the glue.
As we continue to evolve this fabric, we’re making three industry-leading announcements today that help make the fabric more scalable, extensible and open.
Let’s talk about SCALING the fabric first:
Industry’s highest density L2/L3 10G/40G switch: Building upon our previous announcement of redefining fabric scale, this time we introduces a New Nexus 6000 family with two form factors – 6004 and 6001. We expect these switches to be positioned to meet increasing bandwidth demands, for spine/leaf architectures, and for 40G aggregation in fixed switching deployments. We expect the Nexus 6000 to be complementary to the Nexus 5500 and Nexus 7000 series deployments, and is not to be confused with the Catalyst 6500 or Nexus fabric interconnects.
The Nexus 6000 is built with Cisco’s custom silicon, and 1 micro-second port to port latency. It has forward propagated some of the architectural successes of the Nexus 3548, the industry’s lowest latency switch that we introduced last year. Clearly, as in the past, Cisco’s ASICs have differentiated themselves against the lowest common denominator approach of the merchant silicon, by delivering both better performance as well as greater value due to the tight integration with the software stack.
The Nexus 5500 incidentally gets 40G expansion modules, and is accompanied by a brand new Fabric Extender – the 2248PQ, which comes with 40G uplinks as well. All of these, along with the 10G server interfaces, help pair the 10G server access with 40G server aggregation.
Also as part of the first step in making the physical Nexus switches services ready in the data center, a new Network Analysis Module (NAM) on the Nexus 7000 also brings in performance analytics, application visibility and network intelligence. This is the first services module with others to follow, and brings in parity with the new vNAM functionality as well.
Industry’s simplest hybrid cloud solution: Over the last few years, we have introduced several technologies that help build fabric extensibility -- the Fabric Extender or FEX solution is very popular extending the fabric to the server/VM, as are some of the Data Center Interconnect technologies like Overlay Transport Virtualization (OTV) or Location ID Separation Protocol (LISP), among others. Obviously each have their benefits.
The Nexus 1000V Intercloud takes these to the next level by allowing the data center fabric to be extended to provider cloud environments in a secure, transparent manner, while preserving L4-7 services and policies. This is meant to help lower the barriers for hybrid cloud deployments and is designed to be a multi-hypervisor, multi-cloud solution. It is expected to ship in the summer timeframe, by 1H CY13.
This video does a good job of explaining the concepts of the Intercloud solution:
Today marks the general availability of the eagerly-awaited Microsoft Windows Server 2012 platform. According to Microsoft, “Windows Server 2012 redefines the server category, delivering hundreds of new features and enhancements spanning virtualization, networking, storage, user experience, cloud computing, automation, and more.” Earlier Cisco blog posts discussed how Cisco has collaborated with Microsoft to achieve Windows 2012 certification for our UCS servers, as well as integrating our management tools into Microsoft System Center and PowerShell.
In this post, I’d like to highlight the integration of the Nexus 1000V virtual switch into the Windows Server 2012 platform, and particularly the Hyper-V hypervisor. We have been working closely with the Windows Server 2012 team for the past few years towards this goal, and announced Nexus 1000V and VM-FEX support for it at the Microsoft BUILD conference last year.

Nothing sits around and gets stale for long at Cisco (outside the break rooms anyway). On the heels of shipping our Nexus 1000V 1.5.2 release earlier this week (which you can download from here), we are ramping up to show the upcoming generation of the virtual switch next week at VMworld in San Francisco. This new major release 2.1 will be going into beta in October, and will represent a quantum leap in ease of deployment and management, as well as greater security for cloud environments.
vCenter Plug-in – Provides a holistic view of the virtual network to the server administrator from within VMware vCenter. A Nexus 1000V dashboard in vCenter shows the virtual supervisor module (VSM) and virtual ethernet module (VEM) details, such as VSM health status, license information, PNIC information, connected VM’s, et al.
Support for Cisco TrustSec -- Extends Cisco TrustSec security solutions for network-based segmentation of users and physical workloads to virtual workloads, leveraging Security Group Tags (SGT) for defining security segments. Data center segmentation and consistent security policy enforcement can now be implemented across physical and virtual workloads.
Cross Data Center High-availability – Supports split Active and Standby Nexus 1000V Virtual Supervisor Modules (VSMs) across two data centers to implement cross-DC clusters and VM mobility while ensuring high availability. In addition, VSM’s in the data center can support VEM’s at remote branch offices. Read More »
In a blog post earlier this year, I highlighted the Nexus 1010-X virtual services appliance announced at Cisco Live! in London, and why virtual services can be best deployed on a separate UCS-based appliance running NX-OS. The Nexus 1010 and 1010-X are dedicated platforms for hosting virtual service nodes, like the Nexus 1000V virtual supervisor module (VSM), virtual firewalls, and our virtual network analysis module (NAM). All these services run in virtual machines on the Nexus 1010, rather than taking up valuable resources on application servers, and allow for easier manageability by the networking and security teams (rather than the server team).
Continuing on the same theme, this week at Cisco live! San Diego (my how time flies between these shows!), web application firewall (WAF) manufacturer, Imperva, announced that their SecureSphere WAF would soon be available on the Cisco Nexus 1010-X virtual services appliance (Q4 CY 2012). This is the first third-party virtual service announced on either the Nexus 1010 or 1010-X appliance, and provides additional security capabilities on top of Cisco’s virtualization infrastructure for cloud applications.
