Nexus 1100 virtual services appliance
Cisco is unveiling a new beefed up line of virtual services appliances this week called the Nexus 1100 series, the next generation of our Nexus 1010 appliances. These virtual service appliances are integral to the deployment of scalable virtual security and management nodes in the data center, for offloading application servers from running virtual service modules, and for empowering the networking team to retain control of network and security policies in a platform that they manage.
Cisco customers deploying Nexus 1000V virtual switches as the foundation for their virtual networks and virtual overlays typically deploy the Virtual Supervisor Module (VSM), the virtual switch’s management plane, in the Nexus 1100, along with some combination of Virtual Security Gateway (VSG) firewalls, virtual Prime Network Analysis Modules (NAM), Data Center Network Manager (DCNM) for both LAN and SAN networks, and soon, even the Imperva SecureSphere Web Application Firewall (WAF). The Nexus 1100 is a UCS-based appliance for hosting the service VM’s, but it runs the NX-OS operating system, so it can be managed like a network device and retains policy controls for the networking team.

Cisco continues its cloud computing performance leadership with the announcement of Industry’s First VMware vSphere 5.1 Benchmark Result published on September 5th 2012.
With this world-record-setting 8-node VMware VMmark 2.1 score of 42.79@36 tiles, Cisco UCS is best in performance, best in scalability, and the result is the first to incorporate VMware vSphere 5.1—all critical contributors to effective cloud computing environments.
UCS has established many records for Cisco and for the industry with this benchmark result.
- Cisco is best in performance, with a result more than double HP’s best result of 18.27@18 tiles.
- Cisco is best in scalability, outperforming Fujitsu’s result of 36.07@36 tiles by more than 18 percent.
- The Cisco UCS results show that eight 2-socket Cisco UCS B200 M3 servers outperform four 4-socket Fujitsu servers, contradicting the conventional wisdom that vertical scaling outperforms horizontal scaling.
- Cisco is the first to publish VMmark benchmark results on VMware vSphere 5.1, demonstrating the speed at which Cisco UCS can adapt to support new environments and surpass the competition

One area in Microsoft’s new Windows Server 2012 operating system and cloud platform that has seen a lot of innovation is in networking.
Here, Cisco has been collaborating closely with Microsoft at the R&D level for some time on technical and product integration. We’ve got an upcoming webinar on Sept. 26 focusing on Windows Server 2012 and Virtual Networking. Cisco Nexus 1000V Product Manager Appaji Malla and Microsoft Networking MVP John Savill will be co-presenting.
If you are interested in Windows Server 2012 and virtual networking scenarios, then feel free to register here.

………..New Cisco Data Center Security Enhancements
The workplace is changing fast. Workers are becoming increasingly mobile. The introduction of employee-owned consumer devices like tablets, is becoming the norm; in fact, the average number of devices used by knowledge workers is between 3 and 4 and rising. While IT organizations acknowledge the productivity, business agility and cost benefits these developments can bring, they are also concerned by the associated challenges. Not surprisingly, numerous industry research papers point to device, application and data security, and regulatory compliance as the biggest challenges for mobility and BYOD projects.
To address these security concerns many IT organizations are applying desktop virtualization or virtual desktop infrastructure (VDI) technologies to ensure management and protection of the applications, data and content centrally in the data center, regardless of which device is used. But how can IT ensure that VDI deployments themselves are secure?
Today, Cisco announced new data center security enhancements that further protect VDI deployments. These new innovations enable more scalable, secure access to hosted virtual desktops and more robust protection of data center resources. These innovations also ensure that business critical applications and virtual desktops hosted within the data center can be better protected from other virtual desktops that have become compromised or infected. (Read also today’s blog from John N. Stewart , Cisco Sr.VP, Chief Security Officer “Does Virtualization Improve Security ? “)
Deploying a data center infrastructure that has the built-in security capabilities to address these challenges needs to be an integral part of any VDI design. The Cisco VXI Smart Solution is a comprehensive, secure desktop virtualization solution that addresses these security concerns in both Citrix XenDesktop and VMWare View deployments; you can find more information on the designs here.

We all know that the virtualization and cloud megatrend is a game changer for data centers, leading to profound shifts in everything from IT services and business models to architectures. Business benefits include reduced capital investments, new revenue growth opportunities, and the greater efficiency, agility and scalability demanded by globalization.
Enterprises have held back from making the transition to virtual and cloud environments primarily because of the inherent security risks and concerns.
Targeted attacks and security breaches are getting more sophisticated. The Verizon Security Threat Report for 2011 showed that 3.8 million records were stolen in 2010, and 94% of this data came from servers (an increase of 18%).
As security concerns are the primary barrier to making this transition from virtualized data center to cloud, we must rethink how security fits in to these new architectures and develop new security tools to ensure the secure transfer of information.
For enterprises to confidently seize the business benefits offered by data center virtualization and the cloud, security must be seen as the art of the possible, not as a hindrance.
Watch below as I explore the challenges and leading practices for securing virtualized environments today, and into the future.
