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…)

Data Plane Acceleration with 6WIND and Intel DPDK

Data Plane Acceleration with 6WIND and Intel DPDK


6WIND is an interesting company I’ve been following for some time now, initially out of curiosity, and then out of more curiosity :-) . They first started as a networking software company claiming to solve performance challenges for software defined networks (SDN) and network function virtualization (NFV). How you ask? They leverage the capabilities of multicore processors and Intel’s Data Plane Development Kit (DPDK) to allow direct access to the data plane enabling a zero-copy mode from network to CPU! (more…)

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…)

Let’s say you have a Dell PowerEdge M1000e chassis populated with Dell blade servers with CNAs. Let’s also assume you enable FCoE on the CNA and utilize it for LAN and SAN traffic.

What if you were to use the CNA port’s WWPN (World Wide Port Name) within your zoning configuration on a backend Fibre Channel switch? What would occur if the CNA adapter went bad and needed to be replaced? Well, you would have to manually change all configurations that reference the LAN MAC Address or FC WWPN. In this case, the zoning configuration would have to be updated. This is where Dell’s M1000e FlexAddressing technology can help. (more…)

Distributed Core Network Architecture

Friday, January 18th, 2013

There is no doubt you have probably heard by now the importance of supporting ‘east-west’ traffic flow in large data center networks. So why is this and what does it mean? And when Gartner claims that 80 percent of data center network traffic now travels from server-to-server, just what impact does this have on network design/architecture? (more…)

Tech Tips – Check if your E-mail Server is Running [Video]

Wednesday, December 7th, 2011

I created and uploaded this video to youtube back in 2009, but I thought it might be helpful for others if I post the link here. It’s just a simple video that shows you how you can use telnet to determine if your e-mail server is running. Telnet can be a great tool for troubleshooting connectivity and server issues. (more…)
