Network Virtualization in the Software-Defined Data Center

This post co-authored by Bruce Davie, Martin Casado, and Brad┬áHedlund VMware has long been known as the company that changed computing by virtualizing servers. At Nicira, we set out to disrupt networking just as VMware disrupted computing, by virtualizing networks. The analogy between network virtualization and server virtualization can be a helpful one, but it is still only an analogy, and analogies can only take you so far. The point of this post is to dig a bit deeper into network virtualization – what it is, what it means for the industry, and how VMware, in the aftermath of the Nicira acquisition, plans to change networking. Just as server virtualization introduces the abstraction of the virtual machine, network virtualization introduces the virtual network abstraction....

Towards enabling dynamic, elastic, workload-aware networking paradigm

Mallik Mahalingam, Principal Engineer, vSphere Networking R&D, says …   What are the challenges?   Cloud computing holds the promise of using shared resources in a secure, scalable and self service manner.  These basic virtues of cloud computing are placing huge demands on the physical network infrastructure in today’s data centers.  While compute and storage are virtualized, network is the last remaining barrier to workload agility. Networks continue to operate in the old way, tying workloads to underlying physical network and to non-scalable, hard-to-automate constructs. In addition, cloud infrastructure dictates new networking constructs for multi-tenancy, application isolation, scale and increased programmability.   VMware has been working with customers to understand the key challenges as it relates to networking and the cloud. The primary feedback...

Mendel says: It is time for low latency

Those of you who have been reading my blog or listening to my various conference talks since I arrived at VMware last year know I have been arguing there is an important convergence underway between HPC and Enterprise IT requirements. In large part this is being driven by fundamental changes within Enterprise computing, specifically the move towards massive, horizontally-scaled infrastructure to deliver scalable services externally in the cloud or internally for strategic business advantage. As you’d expect with my background, I’ve been looking at this from an HPC perspective, noting that the HPC community has been heavily invested for decades in scale-out cluster provisioning, management, monitoring, etc. And they have built expertise around hardware architectures to support scale-out computing, most particularly in the...
