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…)

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…)

Multitenancy on Dell Networking Switches via VRF-lite

Wednesday, October 29th, 2014

Check out the Dell Networking: Multitenancy with VRF-lite white paper. I describe in detail how multitenency can be achieved on supported Dell Networking switches via Virtual Routing and Forwarding (VRF). VRF-lite supports multitenancy by allowing multiple different routing tables within one physical L3 switch/router. This allows for a multitenant network without having to buy additional hardware. In the diagram directly below, each color represents a different customer tenant utilizing the same IP address space (overlapping IP addresses). Such a setup can also be useful for development and testing where traffic isolation is needed; the overlapping IP addresses can be used for ensuring consistency between each development/test environment.

Dell FC Flex IO Module for Dell MXL/IOA Blade Switch

Dell FC Flex IO Module for Dell MXL/IOA Blade Switch


Very exciting news from Dell today as they announced the availability of the Dell FC Flex IOM module which transforms the Dell M1000e MXL/IOA blade switch into a NPIV Proxy Gateway (NPG). This allows the MXL/IOA to bridge between Ethernet and Fibre Channel allowing for network convergence with FCoE. (more…)
