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.

A key component of Cisco’s Unified Data Center and our virtual networking portfolio is the Nexus 1010 virtual services appliance. We were excited last month when we announced a more scalable version, the Nexus 1010-X. As I pointed out before, the idea of a virtual services appliance is to provide a dedicated hardware platform for running a wide range of network services, monitoring and security virtual machines rather than having them share server resources with key business applications. From an administrative point of view, these network services VM’s can be managed by the networking team, rather than the teams running VM’s on the application servers, which is the right division of labor. The Nexus 1010 platform runs NX-OS and basically looks like a network device rather than a VM host, helping the network admins manage the service policies.
Now we are releasing a case study of an Italian service provider, FASTWEB, who is using the Nexus 1010 to simplify the management of their virtual network, and network service policies. As part of a sustained and forward looking strategy, the Italian service provider has built a next-generation network for delivering converged voice, video, data and mobile services. This investment has enabled FASTWEB to accelerate the creation of new, differentiated offers for business and residential customers, while reducing operational complexity and overhead.
The Nexus 1010 supports network analysis down to the VM layer, giving FASTWEB’s network administrators granular visibility to virtual workloads, without having to trouble the storage and virtualization operations teams.

At Cisco Live London 2012, we announced that the Nexus 1000V distributed virtual switch (DVS) architecture will scale to support 10K+ ports across hundreds of servers. This is a multi-fold increase over our current support of 2K ports and 64 servers. What is driving the need to scale? Two reasons: More VMs and broader VM mobility.
The number of VMs is growing leaps and bounds in data centers and cloud computing environments, which in turn is driving the need to scale virtual switch ports. Depending on who you ask, we have already reached or are about to reach the tipping point where 50% of enterprise workloads have been virtualized. In most IT environments today, you get a VM by default for computing needs; to run an app on a bare metal physical server requires special approval. And needless to say, Moore’s Law continues to drive dense multi-core CPUs with extended memory architectures – thus enabling many more virtual machines to be instantiated on a single physical server. We have seen UCS customers deploy 10 – 30 VMs per server for production workloads, and 50+ (in some cases 100+) VMs per server for non-production workloads and virtual desktops. Increased adoption of public cloud computing resources, as well as growing deployments of private clouds in enterprises is also rapidly increasing the VM count. Also, customers often assign multiple vNICs per VM, e.g. a NIC for data traffic, another for management, a third for backup and so on. These factors are contributing to increased demand for virtual Ethernet (vEth) ports on the Nexus 1000V DVS. Read More »

Nick Lippis of the Lippis Report sits down with Prashant Gandhi, Cisco’s Sr. Director of Marketing for Virtualization in our Server Access and Virtualization Business Unit, to discuss all things virtual in this new video podcast. Prashant does a great job showing why Cisco’s network virtualization stack is the most complete in the industry, including the Nexus 1000V virtual switch, the Virtual Security Gateway (VSG), the ASA 1000V Cloud Firewall, the virtual Wide Area Application Services (vWAAS) WAN optimization solution, Network Services Manager (NSM), Virtual Network Management Center (VNMC), and the Nexus 1010 and new 1010-X Virtual Services Appliance. When you include recently announced technologies like VXLAN and support for the Microsoft Windows Server 8 Hyper-V hypervisor later this year, a great overview video like this can help you keep up with all the recent innovations.

For anyone who has ventured to a tech conference, flown into an airport or even driven down CA highway 101 this past year, it’s clear that cloud is still top of mind for many technical and business decision makers. We believe this means that enterprises are no longer just talking the talk, but are looking deeper into their networking infrastructure to see if they are ready to meet the challenges of cloud, virtualization and workload mobility. At Cisco, it is our job to help build clouds that can handle elastic demand and efficiently use the networking infrastructure at both a virtual and physical level. This week, we are announcing several key upgrades to the Nexus 1000V family that bring scalability and cloud readiness to the network.
