Technology Short Take #21

It’s been a while since I published my last Technology Short Take (found here), and in browsing my list of saved links I find that I don’t really have that many to share. Which then leads to me to ask the question, “Why?” I think it’s because I’ve been sharing lots of stuff via my Twitter account.

In any event, here are some older links that I’ve been saving up to share with you. Many of these posts are a bit older, but I’m including them here just in case someone missed them earlier. As usual, I hope that you find something useful here!

Networking

  • Derick Winkworth describes data center networking as “a messy pile of discombobulated garbage” in his post on the sad state of data center networking. As someone simply observing developments in data center networking from the outside while desperately trying to keep up, now I don’t feel so bad that I don’t necessarily get all of it.

Security

  • Pardon me for the self-promotion, but in order to prevent the ranks of the 600K Macs infected with Flashback from growing, I’d recommend you have a look at this list of 8 things to help secure your Mac. Also, for more details on the latest Flashback variant, see here.
  • Interesting information on a potential VMware security vulnerability is available here. vSphere 5 is not affected.

Storage

  • I posted this article on Twitter, but wanted to share it here as well. This post by Richard Elling on IOPS and latency is, in my opinion, a must-read.

Virtualization

That’s going to do it this time around. Feel free to speak up in the comments below to add your thoughts, other links you’ve found useful, or anything else. Thanks!

    Hi Scott,

    I found Rich Elling’s blog post (in the Storage section) interesting. However I’d point out the inverse non-linear relationship between bandwidth and latency. E.g., http://perfdynamics.blogspot.com/2009/08/bandwidth-and-latency-are-related-like.html or http://perfdynamics.blogspot.com/2010/03/bandwidth-vs-latency-world-is-curved.html

    Because there is a queue, I think Little’s Law is applicable.

    Regards,
    Scott Johnson
