Internets of Interest for 4th February

Collection of useful, relevant or just fun places on the Internets for 4th February and a bit commentary about what I’ve found interesting about them:

  • Real World Technologies – IBM z196 Mainframe Architecture – A amazing insight into the hardware architecture of the IBM mainframe. Lots of insights into how a different hardware architecture works. Reminder that good hardware design delivers enormous performance benefits – compare that with utility servers that do nothing well.
  • Brocade Communities : Service Providers: The Brocade OpenScript Engine: Carrier-Grade Flexibility for Scalable and Reliable Application Delivery – This article outlines Brocade’s OpenScript Engine. In short, it’s an XML API that provides a lot of configuration functionality so that programmable control of network devices is possible. This is the alternate solution to OpenFlow where vendors deliver worthwhile APIs for DevOps functions. Check out the nifty perl scripts demos – very cool.
  • SPDY Brings Responsive and Scalable Transport to Firefox 11 ✩ Mozilla Hacks – the Web developer blog – Firefox adds SPDY to their browser to improve the performance of HTTP as a TCP protocol. Chome already supports SPDY so the Internet will get faster in the near future. SPDY is going to cause a lot of companies to upgrade their web servers because it’s going to make a huge difference.
  • What Does FCoE Have To Do With VM Mobility? – blog.scottlowe.org – The weblog of an IT pro specializing in virtualization, storage, and servers – Scott Lowe discusses the issue of mobility is also an unsolved problem for the storage industry as well. It’s not only a problem in networking.

    As you can see, VM mobility and storage isn’t an FCoE problem—it’s a storage problem, plain and simple. Protocols can’t fix it. What’s needed to fix it is a fundamental shift in how storage is designed.

  • CCIE Numbers Skyrocket – Red Alert? | The Networking Nerd – While it’s obvious to me, I’m pretty well traveled through Europe, Asia and Africa so I tend to think globally, but not everyone is able to see the big picture. Tom does:

    Stop and think about it for a minute.  According to Cisco, China is seeing explosive growth in networking, everything ranging from power systems to survellience.  They’re ramping up and infrastructure that’s going to need to support over a billion people all looking to get connected somehow.  China is leading the way in deploying IPv6 internally as a way to alleviate the exhaustion of IPv4 addresses.  Ask yourself then: Where are they getting all these engineers?  How many of your friends and colleagues are flying to China to work on these massive projects?  I’m guessing hardly any.  Why’s that?  Where is the supply coming from to meet this massive demand?

  • Cisco Nexus 7000 M2-Series 6-Port 40 Gigabit Ethernet Module with XL Option Data Sheet  [Cisco Nexus 7000 Series Switches] – Cisco Systems – On one hand, finally a multiport 40GB line card for the Nexus 7000. On the other hand, check out the amount of silicon on that line card!!! Is that really necessary ? Look more like a space heater or a prototype board.
  • Why Apache is important to Openflow – OpenFlow Hub News – BigSwitch tells a little more about open sourcing their OpenFlow controller which is a major event for the OpenFlow/SDN community.

    This is why we created the Floodlight OpenFlow Controller and chose the Apache license for it.Why is Apache so important for Floodlight and OpenFlow?  As OpenFlow makes the shift from academia to industry, it’s important to offer a truly free, open development platform that does not place any limitations on how OpenFlow is used or commercialized.  A liberal open source license will play a key role in fostering innovation in a startup ecosystem, attracting key industry players, and easing enterprise adoption.

  • FlowScale Home – FlowScale – OpenFlowHub – OpenFlow news and projects

    FlowScale is a project to divide and distribute traffic over multiple physical switch ports. FlowScale replicates the functionality in load balancing​ appliances but using a Top of Rack (ToR) switch to distribute traffic. Using software to handle the control plane specification but switch hardware to do the forwarding gives both great flexibility and allows for low cost, high throughput deployments.

    It’s a Flow Balancing load balancing app for SDN/OpenFlow.

  • Enterprise Support – Symantec Corp. – Ports used for communication in Symantec AntiVirus 10.x and Symantec Client Security 3.x-Using Symantec AntiVirus and Client Security products ? Get ready to punch serious holes into your firewalls. They use vast ranges of port addresses to/from clients, and between servers. Basically, add Symantec products and your network security posture gets punched full of major holes.

    Stupid security in action. Again.

  • Eight Unresolved Questions About FCoE – @SFoskett – Stephen Foskett, Pack Rat – Goor review of the issies that prevent FCoE from being adopted by most organisations.

    Now that FCoE is specified in the standard and has been deployed in production environments, the question turns to its future. Will it take off and seize the mantle of dominance currently held by what I like retroactively to call “Fibre Channel over Fibre Channel?” Will they coexist for the next decade, with FCoE mainly deployed in “block” environments such as Cisco UCS? Or will FCoE ultimately fail to catch on, displaced by some other storage protocol like plain FC, iSCSI, NFS, or something entirely different?

    Foskett nails all the major points that FCoE has not yet solved. Great article.
