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 »

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.

Greg Ferro and Ethan Banks from PacketPushers.net have released another in-depth podcast, this time on how to create scalable cloud networks with VXLAN. VXLAN, if you recall, is a multi-vendor effort to increase the number of logical networks that can be created within a cloud environment, and overcomes the challenges of using VLANs when separate tenants and application instances all need their own logical domains.

Captain’s log, October 27, 2011:
The USS Cisco took off for the Gestalt IT Networking Tech Field Day 2 with Captain Omar Sultan (see picture below, courtesy of techfieldday.com), Data Center Solutions Sr. Marketing Manager, at the helm. Tech Field Day networking industry experts gathered on the bridge, cleverly disguised as the Cisco Cloud Innovation Center (CICC) Lab, for an informal, no-holds-barred conversation on recent Nexus portfolio announcements, the continued march towards automated provisioning of cloud services and ever-evolving VM networking technologies.

For those who weren’t at the event or haven’t seen the video recording yet, please excuse my unabashed geekiness, but you’ll have to watch the first minute of the video to get the above reference. As a new member of the Data Center Solutions Marketing team, this is also my first foray into the Cisco blog-o-sphere, so I hope to share some fresh viewpoints on the day’s events.
Several things were made very apparent during the Tech Field Day session:

So, here is our final installment–we are wrapping up with some of the more common questions were are seeing. In you missed the earlier posts, be sure to check out Part 1 and Part 2. I also have a couple of earlier posts introducing VXLAN and answering some of the initial questions.
So, onto the FAQs… Read More »
