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.

Cisco has just released a customer case study (PDF) of CareCore National, a 1200 person healthcare insurance company located in South Carolina. CareCore’s use case demonstrates how Cisco’s Virtual Security Gateway (VSG) for the Nexus 1000V can be used in a virtualized data center to logically isolate virtual machines running on shared application servers to meet compliance requirements.

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.

Cisco is announcing this week a new member of the Nexus 1000V virtualization infrastructure portfolio, the Nexus 1010-X virtual services appliance. The new Nexus 1010-X is an extended version of the existing Nexus 1010 appliance, and represents a larger, more scalable and cost-efficient configuration for larger data center deployments and cloud applications. What is a virtual services appliance and why should customers use it? The Cisco Nexus 1010 and 1010-X provide improved management, scalability and visibility in environments running the Nexus 1000V virtual switch and the VMware vSphere hypervisor. Read More »
