Cisco UCS & Cisco Nexus – Making M&Ms and VMs Awesome!

Based on the positive feedback I received from my Cisco UCS videos, I decided it was time to tackle a slightly more complicated set of topics. While it’s fairly easy to come up with a set of keywords that spell out C-I-S-C-O, sometimes it’s valuable to take off the training wheels and go a little broader. So in today’s video, we combine the simplicity of M&Ms with the complexity of VMs. How do we take technology that provides tremendous value to customers and explain it in a way that’s fun and easy to replicate? Well, let’s see what happens… Read More »

UNS Spotlight on VM-ready Security Solutions with VSG

May 19, 2011 at 4:12 pm PST

The Unified Network Services (UNS) portfolio of Layer 4-7 services (such as ACE and WAAS) also includes Cisco’s data center security solutions. A critical part of that security portfolio is our virtualization-aware firewall solution, Virtual Security Gateway (VSG). In a series of upcoming blog posts, I’ll be sharing a few use case scenarios that our customers are implementing with VSG.

For those of you new to VSG, I’ll point out that VSG’s role is to act as a virtual firewall between zones of virtual machines. Isolating traffic between VM zones has been very challenging prior to VSG because: 1) security policies have to be enforced between VMs running on the same server or same virtual switch (where there’s no place to put a firewall), 2) VMs move all around the network and the security policies (as enforced in the firewall) must follow the VM, and 3) the need to maintain segregation of duties for compliance purposes between the security and application server teams, where security is potentially enforced inside the virtual server.

Optimize the Data Center

March 3, 2011 at 11:30 am PST

CiscoLive London was an incredible trip and gosh it was only 30 days ago – our first little project out of that voyage is TechWiseTV85 our latest episode on Data Center technologies.  Data Center Optimization: The Next Stage is now available for your viewing pleasure in our ‘still has that new website smell’ environment we affectionately call the CVC (Cisco Virtual Connection).

This show was another exercise in self-restraint as the DC team had brought out an amazing selection – if we were hoping that a global show would mean a smaller show…we were out of luck.

So how to narrow it down?

Why the Network Matters for Virtualization and Cloud Computing

I’ve written before (here, here, and here) that Cloud Computing is more than some cool software running on a server. Sure, the applications are the sizzle on the steak (+ all the marketing terms -- dynamic, elastic, on-demand, etc.), but there’s a little more to it than that. A user needs to access the application, get the information quickly (or sent it information), and feel confident that the information was delivered securely. The application doesn’t always know what type of device will access it (PC, Mac, Browser, Tablet, Smartphone, etc.), so it can’t be 100% sure it’ll deliver the best user-experience.  And users will demands that applications continue to run regardless of the mobile device’s location. All those demands on applications get a lot easier, and in some cases require, an intelligent network providing the infrastructure.

But people often forget those details because they have become so accustomed to a robust network always being there. They might struggle to define the value of that network, just as Kodak did in defining “original technology” in the famous Mad Men episode (Carousel).

Don’t take my word for it, hear what Cisco Cloud CTO Lew Tucker had to say during a recent set of meetings with industry analysts -- here, here, here, here and here. Read More »

Services, Services Everywhere

[Part IV of our blog series on Cisco Data Center Business Advantage. Part I, II, III, V, VI]

With all the of the changes happening with the Data Center, the IT department is constantly faced with the challenge of balancing “the new coolness” (Virtualization, 10Gb Ethernet, Cloud Computing, Unified <insert_technology_here>) and still being able to manage the daily operations of the business. Adding to the challenge is the changing architectures that these new technologies bring to the Data Center. Read More »
