Hyper-Converged with Dell-VMware EVO:RAIL

Friday, May 29th, 2015

Dell-VMware EVO:RAIL Hyper-Converged Solution
There’s a lot of interesting things going on in the industry with servers, storage, and networking: SDN (software defined networking), SDS (software defined storage), NFV (network function virtualization), SD-WAN (software defined WAN), hyper-convergence, and more and more focus on private / public / hybrid cloud just to name a few. I’ve written several prior posts on VMware NSX and SDN. In this short blog, I’ll focus on hyper-convergence specifically with the Dell-VMware EVO:RAIL solution. If you haven’t already, checkout the Dell Networking Dell-EVO:RAIL Reference Architecture for more detailed information. (more…)

Dell Open Networking and SDN – All About Disaggregation

Sunday, May 10th, 2015

Dell Open Networking
When Dell first announced its Open Networking initiative a little over a year ago, they were the first major networking vendor to do so. Very similar to what Dell did for servers, Dell is now doing for networking – allowing customers to choose their hardware and then choose what operating system they want to install. (more…)

VMware NSX Service Composer: Advanced Security & Micro-segmentation

Monday, March 16th, 2015

NSX Security Groups
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…)

Cumulus Linux on Dell Switches: Spine-Leaf Architecture & OSPF on Unnumbered Interfaces

Sunday, January 18th, 2015

In a prior blog, Cumulus Linux on Dell Networking Switches, I demonstrated how to install Cumulus Linux on a Dell S6000 switch and do some basic configuration. In this blog, I’ll demonstrate how to configure routing on Dell switches running Cumulus Linux. The example covered demonstrates a Spine-Leaf architecture with OSPF on unnumbered interfaces. In this example 2 x Dell S6000-ON and 2 x Dell S4810-ON switches [Cumulus Linux 2.1.1] are utilized. The lab setup is depicted by the network diagram below. (more…)

Dell VRF-lite & VMware NSX: Multitenancy Across Physical & Logical Networks

Saturday, December 20th, 2014

Please checkout the white paper Dell Networking: Multitenancy Across Physical and Logical Environments with VRF-lite and VMware NSX. In the white paper I discuss use cases and how NVO and VRF-lite can be used together to deploy a consistent multitenant framework across logical and physical networks. In this short blog, I expand on the concept I presented in a prior blog, Multitenancy on Dell Networking Switches via VRF-lite, of how NVO and VRF-lite together can be used to deploy a consistent multitenant framework across logical and physical networks.

Firewalling & Micro-segmentation with VMware NSX

Monday, December 8th, 2014

One very exciting and strong use case for VMware NSX is advanced security. VMware NSX has some inherent security features and also allows for 3rd party security appliance integration. In this blog, I’ll briefly discuss the firewalling and micro-segmentation capabilities of VMware NSX-vSphere. (more…)

Cumulus Linux on Dell Networking Switches

Sunday, November 16th, 2014

Dell Networking S6000 with Cumulus LinuxIt’s pretty cool that Dell allows its customers to install other network switch OSes on their networking switches; it’s the only major networking hardware vendor in the industry that allows for this. Other networking hardware vendors tie their proprietary network switch OS to the networking hardware they sell. Two Dell switches you can currently buy that support operating systems by other vendors are the Dell S6000-ON switch and the Dell S4810-ON switch. These Dell Networking switches come installed with the Open Network Install Environment (ONIE). ONIE is open source and defines an open “install environment” for bare metal network switches allowing customers to install their choice of OS. (more…)

Dell Networking and VMware NSX: Bridging Between Logical & Physical Networks

Wednesday, November 5th, 2014

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.
