Cisco Unified Computing System is 75% Networking - Who Knew?

I thought I'd delve into a slightly less controversial subject this week (well, maybe). My technical background lacks significant hosting experience (servers, storage, operating systems, etc). I understand hosting systems and how...

Congress Needs to Step In for Net Neutrality...Really? Seriously?

If you caught my blog back in March on "Net Neutrality for Dummies" you'll probably understand quickly I am of the belief that Net Neutrality is a solution in search of a problem. The scare mongering that goes on about Net...

It's Time to Start Loving Tunnels

I wrote a blog two years ago about how I could fix anything with a tunnel. Yes, it was a tad tongue in cheek, but it also had some truth to it. Tunnels are a weapon to use when faced with a difficult network design issue. However,...

Carlos Dominguez, SVP, Office of the Chairman and CEO and emcee of the Cisco Live keynotes started off the keynote today with a short slide show on funny signs in Las Vegas. So, poignant that I saw this in the lunch line today. ...

Our Cisco Live Certification Gift

I stopped by the Cisco Live World of Solutions Certification Lounge last night and was handed a "gift" at the door. What are these things? :-) I think they made a movie about these metal balls. I guess we're supposed to...

CCDE Recertified!

The test itself still had a bunch of errors in it, not as bad as when I took the beta written, but still dissapointing. Like traffic flows in the question that had incorrect router names and diagrams with the "HQs Site" labeled...

Cisco Live 2010 Wireless Performance

WLAN was not on this morning when we started, but the SSID showed up shortly afterwards (maybe it was the room I'm in). Performance has been pretty decent. On WLAN to San Francisco: On WLAN to NYC: AT&T 3G in my...

Cisco Announces the CCIE Emeritus Program

Last week, I had a chat with Fred Weiller, Director of Cisco Marketing, who gave me a sneak preview of the new "CCIE Emeritus" certification status Cisco announced today. CCIE Emeritus was developed in response to very experienced...

The CCIE Party at Networkers Has Big Potential This Year

What can I say? I like a good CCIE party when I go to Networkers. Before my first Networkers in 2005, I got a simple e-mail about the CCIE party which would be during the customer appreciation event. Given the simplicity of the...

The New Cisco Nexus 2232PP Is Nice!

Remember the catch-phrase in Field of Dreams - "Build it, and they will come."? The pretty much sums up our experience with 10GbE host connectivity over the past year in our new cutting-edge, 10GbE data center. We built the...

Layer-0 Page for Network Design Templates

The third blog on wrote on Network World's Cisco Subnet was about Network Design Templates. Proper Network Design Templates are one of the pillars of a written network architecture. If you work on a network engineering and...

Nexus 5000 Only Supports 16 EtherChannels

An interesting, and most likely uncritical, factoid popped up this week while our operations team was configuring a set of Nexus 5000 switches for 10GbE connections to blade servers in our DC. By default, our interface...

A Graphical View of My Idea of WAN Acceleration and More Bandwidth

I wrote in a blog two weeks about that I was dissolusioned by WAN Acceleration. It just hadn't made the incredible difference I was expecting, given our current bandwidth sizes. However, at the end of the blog, I mentioned a...

I Have Been Disillusioned by WAN Acceleration

DISCLAIMER: If you work for a WAN Acceleration vendor, please do not e-mail saying "our technology is different" or "we can make it work for you". Except for some different tweaks, in general, it's the same. Please don't...

WAN Carriers Need Better Bandwidth Pricing Models for Enterprises

Two weeks ago I wrote a blog asking "should enterprise IT provide great Internet access?". Essentially, enterprise WANs usually give 3-10 Mbps to a field site and 100-200 users need to fit inside that bandwidth. Meanwhile, these...

I Got an iPad

Yes, I waited in the brutal line in the driving rain yesterday for 6 hours...... Ok.....actually, I got there around 8 AM, found a chair to sit in and listened to and read news on my iPhone during a beautiful Saturday morning...

Is Enterprise IT Here to Provide Great Internet Access?

The natives in the field sites at work are restless. The complaints about the "network is slow" have been building recently. One manager at a sales office sent an e-mail with a one-liner I'll have to use again someday: "IT is...

Latency in the Data Center Matters

It's been an interesting week at work. Make that two weeks. For the last couple of weeks, we have been working on a throughput performance issue between a very expensive Fujitsu M8000 server and network storage over our 10GbE...
