Talking Hyper Convergence with “The GreyBeards”

Recently Ray Lucchesi shot me an email asking if I’d like to be a guest on he and Howard Marks podcast “GreyBeards on Storage”.   I’ve known both Ray and Howard for quite some time and love the debates and industry banter we always get into, so naturally I couldn’t refuse the offer. In the podcast we talk about the real definition of what hyper converged systems are and how they’re different from the converged hardware systems that you see elsewhere in the industry.  Check out the link or listen below and definitely subscribe to the GreyBeards on Storage podcast.

Sliced Bread

I recently read an article published in Wired (http://www.wired.com/2014/06/google-kubernetes/) talking about how Google has open sourced Kubernetes, their implementation of container cluster management.  It is used to more easily and efficiently run web applications over a large array of computing resources.  According to Craig Mcluckie, a product manager for Google’s cloud services “It’s a way of stitching together a collection of machines into, basically, a big computer”.

I’m not really writing to talk specifically about this technology, but more the value of open sourcing.  So many of the technologies that are used in IT today have come from the advances made by opening software to be adopted by a wider base.  Having access to these technologies allows startups and communities easy access to technology, but more importantly, it facilitates combining other technologies in a way that have not been done before.  It’s like the old adage  “it’s the best thing since sliced bread”.  The guy who invented sliced bread didn’t invent bread, and he didn’t invent slicing.  He just combined two things in a way that hadn’t been done before.  IBM ran a great commercial years ago that highlighted this (http://youtu.be/Io-S9iv9ucY).  One of the great advantages of open sourced technologies is that it allows true innovation by letting others combine things in a way that has not been done before, which in turn creates something completely new.

In Google’s example they use Kubernetes in concert with other technologies such as Docker to provide a solution for the problem they are trying to solve.  One easy way to think about it is that Docker is a tool for packaging up web applications into a “shipping container”, then Kubernetes is the trucking/logistics company that moves those shipping containers around in a more efficient manner to utilize the available resources.

At Scale we make several varieties of “sliced bread” within our products.  For example we use the open sourced hypervisor KVM, then combine that with SCRIBE our distributed block engine that we use for storage.  Because KVM is open source it allows use to tie directly into SCRIBE thereby bypassing the need for network storage protocols like iSCSI and NFS.  This in turn makes the product both simpler and faster.  To quote RFC1925 “In protocol design, perfection has been reached not when there is nothing left to add, but when there is nothing left to take away.”

 

Catching up on VMworld and Hyperconvergence

Finally catching up post Vmworld, Vanessa Alvarez and Jason Collier catch up on all things hyper convergence, virtualization, private cloud, and their new storage architecture SCRIBE.

SCRIBE was introduced as a technology preview at Vmworld and is the future of HC3. In today’s IT organization, there’s no time to deal with complex and expensive infrastructure environments. The introduction of SCRIBE for HC3 further simplifies IT for businesses and takes them through the journey of server consolidation, private cloud and the vision of a software defined environment.

VIDEO: The Twelve Networking Truths – RFC 1925 Truth No. 5

RFC 1925 Truth No. 5: “It is always possible to aglutenate multiple separate problems into a single complex interdependent solution. In most cases this is a bad idea.”

So to paraphrase truth No. 5, complexity is a bad thing.  However, this is exactly how virtualized infrastructures are built today. Continue reading

The Twelve Networking Truths

It started as an April Fool’s joke in 1996 when Ross Callon drafted RFC 1925 “The Twelve Networking Truths.” The purpose of this RFC was to “provide information about the fundamental truths underlying all networks.” Though this started as a joke, it has some real nuggets of wisdom that apply as much today as when it was originally written. I’m also posting this as a video blog over the coming weeks where I will also be going into a few of these truths in more depth as they apply to our overall industry. (My first detailed video blog post will be related to truth No. 5.) As a reference, I’ve posted the 12 networking truths below. They can also be found here: (http://tools.ietf.org/html/rfc1925).
