In a prior blog, Firewalling & Micro-segmentation with VMware NSX, I discussed some of the basics of firewalls and micro-segmentation with VMware NSX. In this blog, I’ll introduce how security groups via NSX Service Composer can be used with VMware NSX to further enhance the micro-segmentation and security capabilities. (more…)

In a prior blog, Creating Logical Networks and Services with VMware NSX on Dell Infrastructure, I discussed how easily VMs can be moved from physical (VLANs) to logical networks (Network Virtualization Overlays or NVOs). In practicality, there will almost always be some physical resources on a network that are not virtualized or remain on the physical network (VLANs). So how can VMs on a logical network communicate with resources on the physical network?
One method of communication can be done with the VMware NSX L3 Edge Services Router. However, if you want to just bridge between the logical and physical entities such as bridging between VXLAN to VLAN, the VMware NSX L2 Gateway can be used and this specific use case is discussed in more detail in this blog.

If you haven’t already, please checkout the Dell-VMware NSX Reference Architecture (RA) whitepaper. In the reference architecture I explain in detail the foundational NSX-vSphere components and also how Dell can provide a complete end-to-end infrastructure (servers, networking, storage) to support a robust SDN solution with NSX. In this blog, I will provide a quick overview, some insight on NSX, and examples of VMware NSX deployment with a complete end-to-end Dell infrastructure. (more…)
Below is a link to the slide deck for a presentation I gave to some friends/colleagues for a Berkeley Virtualization and Cloud Computing certification course I took in early 2012. For my final project I did a XenServer, Hyper-V, and ESXi hypervisor comparison in regards to market share, architecture/installation, and APIs/coding. The project involved not only a presentation but coding for all three hypervisors – XenServer, Hyper-V, and ESXi. Technical details, demos, and coding examples are provided in the presentation. You can also download all code from either the download section of this site or for the latest code updates download from GitHub. (more…)
The Open Virtual Machine Format (OVF) describes a format for the packaging and distribution of virtual machines (VMs). It is touted as open, secure, and portable. OVF can be seen as a packaging format for software appliances. I see it as a self-contained software solution that allows for VMs to be moved from one hypervisor to another. (more…)
VMware vSphere is an industry leading virtualization platform. Basically it is a software suite composed of applications directed towards managing datacenters through the use of virtualization technology. I’m going to briefly discuss some of the major/core components of vSphere 4. This will give you a clear idea of some of the power behind vSphere 4 and virtualization technology in general. For more information/documentation and a full list of benefits offered by vSphere 4, you should check VMware’s website. (more…)
