By the time you read this, I’ll be down at Oak Island on the North Carolina Coast, where my wife will be getting the turkey ready, and making a white chocolate cheesecake. No, I won’t tell you the address, but I will tell you this.
I’m thankful for this year.
I’m thankful for my family. For my wife and kids who put up with me and my insane schedule.
I’m thankful for my friends (I would list them all, but I’d probably forget someone, which would hurt feelings; it just doesn’t seem right to hurt anyone’s feelings today). Across the years, I’ve been taught so much about networking and engineering in the last 20+ years, from working on RADAR systems to large scale data centers. I’ve been given so many opportunities to write and speak, and been shown how to be just a better person.
I’m thankful that God has opened a door into a top notch PhD program, the support structure every PhD student needs to succeed, and two great mentors (more than anyone could ask for).
I know it’s not Thanksgiving in every country in the world. But there’s never a bad day to give thanks for what Continue reading
Almost every year a joke RFC is made on April 1st (these have caught on so well, that it’s now common to see more than one of these every year
Verizon's cloud technology, Radware's business deals, and Iguaz.io's $15M storage plans adorn this week's roundup.
Hello everyone. I hope you are well. After this discount news I think you will be much better Check the Products page for all the discounted products. You have many [..]

Wow, another year swooshed by. I can’t believe it’s almost gone. Maybe it’s all the travels I had throughout the year, and I MUST start with a huge THANK YOU to whoever is watching after me – there wasn’t a single major SNAFU.
Next, I’d like to thank the people who caused all that travel: attendees of my workshops.

If you haven't heard what they actually did you'll hardly even believe it. That's this week's feature interview.
Last night I finally finished watching all of the Big Switch Networking field day 10 videos. If you haven’t seen them yet, I’d recommend taking a look out at them out on YouTube…
Big Switch Networks – Overview
Big Switch Networks – Why SDN Fabrics?
Big Switch Networks – Big Cloud Fabrics
Big Switch Networks – Big Cloud Fabric GUI demo
Big Switch Networks – Big Cloud Fabric for VMWare
Big Switch Networks – Monitoring Fabric
All of the presentations were awesome and well worth your time especially if you’re new to their products.
If you haven’t looked at Big Switch before, their name sort of says it all. Their base concept is disaggregating a standard chassis switch into individual components. The breakdown would look something like this…
As you can see, each component of a standard data center chassis switch has a similar component in the Big Cloud Fabric. Leaf switches are the new line cards, spine switches the fabric modules or backplane, and the Big Cloud controller is the supervisor. Big switch then uses a standard IP management network to connect all of their components together. This isn’t a very big Continue reading
An IoT trial is the latest in a flurry of Ericsson partnerships.
New advances open the gate for SDN in the optical arena.
The Datanauts get nerdy about the work needed to deploy infrastructure and software into the modern data center. What are lessons learned from building from scratch (a.k.a traditional architecture) vs. buying a converged system?
The post Datanauts 015: Modern Data Center Design: Traditional Architecture or Buy a Stack? appeared first on Packet Pushers.
A while ago I described why some storage vendors require end-to-end layer-2 connectivity for iSCSI replication.
TL&DR version: they were too lazy to implement iSCSI checksums and rely on Ethernet checksums because TCP/IP checksums are not good enough.
It turns out even Ethernet checksums fail every now and then.
2015-12-06: I misunderstood the main technical argument in Evan’s post. The real problem is that switches recalculate CRC, so the Ethernet CRC is no longer end-to-end protection mechanism.
