Developer: Network team, did you order the Code upgrade?! Operations Manager: You don’t have to answer that question! Network Engineer: I’ll answer the question. You want answers? Developer: I think I’m entitled! Network Engineer: You want answers?! Developer: I want the truth! Network Engineer: You can’t handle the truth! Son,…

Oh, the Places You’ll Go! (A Cisco ACI Story)
In the fashion of my two previous Dr. Seuss style stories I thought I’d take a crack at Cisco Application Centric Infrastructure (ACI.) Check out the previous two if you haven’t read them and have time to waste: Horton Hears Hadoop: http://www.definethecloud.net/horton-hears-hadoop/ The App on the Crap (An SDN…
It’s Our Time Down Here– “Underlays”
Recently while winding down from a long day I flipped the channel and “The Goonies†was on. I left it there thinking an old movie I’d seen a dozen times would put me to sleep quickly. As it turns out I quickly got back into it. By the time the…
Network Management Needs New Ideas
As networks have grown, the industry has sought better ways in which to manage them at scale. Traditional network management systems are typically device-centric, particularly for network infrastructure. These systems take a top-down management approach and use a central server to push configuration into devices and to manage device state….
WWT GeekDay 2013
I had the privilege this week to attend the opening keynote and SDN panel of WWT’s Geek Day. The SDN panel was made up of heavy hitters from Cisco, VMware, HP, and Embrane. They each presented their vision and solutions for SDN, then teamed up for questions. The session was…
Network Overlays: An Introduction
While network overlays are not a new concept, they have come back into the limelight, thanks to drivers brought on by large-scale virtualization. Several standards have been proposed to enable virtual networks to be layered over a physical network infrastructure: VXLAN, NVGRE, and SST. While each proposed standard uses different…
Why We Need Network Abstraction
The move to highly virtualized data centers and cloud models is straining the network. While traditional data center networks were not designed to support the dynamic nature of today’s workloads, the fact is, the emergence of highly virtualized environments is merely exposing issues that have always existed within network constructs….
VXLAN Deep Dive
I’ve been spending my free time digging into network virtualization and network overlays. This is part 1 of a 2 part series, part 2 can be found here: http://www.definethecloud.net/vxlan-deep-divepart-2. By far the most popular virtualization technique in the data center is VXLAN. This has as much to do with Cisco…
Something up Brocade’s Sleeve, and it looks Good
Brocade’s got some new tricks up their sleeve and they look good. For far too long Brocade fought against convergence to protect its FC install base and catch up. This bled over into their Ethernet messaging and hindered market growth and comfort levels there. Overall they appeared as a company…
