What Impact Can Virtualization Have on the Field of Research Computing?

Challenges for IT supporting research computing environments What is most important to an IT department supporting university research? Based on conversations with many of our customers, we have repeatedly heard the following: Satisfying the varied and sometimes conflicting requirements of different research groups, which may include compliance issues for bioinformatics research Showing the value of centralized IT resources against buying isolated equipment or outsourcing to a public provider of infrastructure Meeting these goals while on a limited budget For many independent research teams, each desired environment typically involves its own set of simulation and analytics tools, including different operating systems and other middleware components. For example, different environments and tools are used for genomic research than for reservoir simulation. Satisfying these disparate requirements is...

Managing IT resources across complex enterprises has historically been challenging, and those challenges are only increasing in complexity. We’re adding more variables in terms of clouds, automated processes, and people, to name a few. Consider the steady growth of Internet of Things (IoT) and for many organizations, their management complexity can potentially expand by several orders of magnitude. If that’s not bad enough, there’s one variable that IT has never been able to historically control – people. People come and go and often play by their own rules. When it comes to managing an enterprise, we can no longer assume that people will conform to defined enterprise management standards. Instead, IT operations must conform its standards to the customers it serves. That is why...

Supercomputing '14 Begins: Laissez les bon temps rouler!

  SC'14 , the big, annual High Performance Computing (HPC) conference officially kicks off in New Orleans this evening with the opening of the exhibits. Workshops and tutorials have been held over the weekend as well: I gave a keynote presentation on Sunday at the 4th International Workshop on Network-aware Data Management ( NDM'14 ), titled RDMA in the Cloud: Enabling high-bandwidth, low-latency communication in virtual environments for HPC (slides:  NDM'14 keynote ). While I've been attending SC since the late 1980s and have attended each year I've been at VMware, this year marks the first time VMware will have an official presence on the show floor. We've partnered with EMC's Office of the CTO...

High Performance Computing (HPC) Update

Our HPC effort at VMware has been very active in recent months, and we have lots of information to share-- including new performance results. Rather than cramming all of that content into a single mega blog entry, I've decided instead to give a preview here of some of the most significant developments. I will then delve into each of these areas in more detail in a series of upcoming monthly blog posts. InfiniBand Performance This spring we installed a four-node InfiniBand HPC cluster in our lab in Cambridge, MA. The system includes four HP DL380p Gen8 servers, each with 128 GB memory and two Intel 3.0GHz E5-2667 eight-core processors and Mellanox ConnectX3 cards that support both FDR (56 Gb/s) InfiniBand and 40 Gb/s RoCE....

VMware and Docker – Better Together

Today at VMworld 2014 I have the pleasure of co-presenting with Ben Golub, Docker CEO, on our joint container strategy. Our session, “ SDDC3350 – VMware and Docker – Better Together ,” will run on Monday from 5:30-6:30 and on Tuesday from 12:30-1:30. For more insight into the work that we are doing with containers, I encourage you to take a look at the following posts: VMware + Containers = Containers without Compromise Docker Service Broker for Cloud Foundry Gartner Panel Reveals Stark Differences in Container Based PaaS Options Combined architectures that leverage both containers and VMs are nothing new. Cloud Foundry Warden first supported this approach in 2011. In addition, Amazon EC2 first supported containers via LXC in...

Don't Be Fooled By Import Tools Disguised as Hybrid Cloud Management

Don't Be Fooled By Import Tools Disguised as Hybrid Cloud Management

The biggest part of my job is speaking with end user organizations and understanding their greatest current and future challenges. Oftentimes I hear about workloads that are initially developed on a particular cloud provider's infrastructure that cannot be redeployed or migrated anywhere else. To be clear, nothing is technically impossible. It's always a matter of the migration costs outweighing the benefits. Many times organizations want to move workloads developed in a public cloud to their private cloud for reasons such as security, compliance or lowering costs. In other cases, service stacks may need to be distributed globally to 40 or more countries and rebuilding those stacks on various infrastructures can cost millions. The bottom line - the organizations that I speak with daily are...
