Thoughts on #OpenStack and Software-Defined Storage

This week has been the semi-annual OpenStack Summit in Atlanta, GA. In a rare occurrence I’ve been able to be here as an attendee, which has given me wide insight into a world of Open Source development I rarely get to see outside of some interpersonal conversations with DevOps people. (If you’re not sure what OpenStack is, or what the difference is between it and OpenFlow, OpenDaylight, etc., you may want to read an earlier blog I wrote that explains it in plain English).

On the first day of the conference there was an “Ask the Experts” session based upon storage. Since i’ve been trying to work my way into this world of Programmability via my experience with storage and storage networking, I figured it would be an excellent place to start. Also, it was the first session of the conference.

During the course of the Q&A, John Griffith, the Program Technical Lead (PTL) of the Cinder project (Cinder is the name of the core project within OpenStack that deals with block storage) happened to mention that he believed that Cinder represented software-defined storage as a practical application of the concept.

I’m afraid I have to respectfully disagree. At least, I would hesitate to give it that kind of association yet. Read More »

Next Generation Data Center Design With MDS 9710 – Part I

Note: This is the first of a three-part series on Next Generation Data Center Design with MDS 9700; learn how customers can deploy scalable SAN networks that allow them to Scale Up or Scale Out in a non disruptive way.  Part 2 | Part 3 ]

High Speed (16Gbps) and High Capacity (384 Line Rate ports per Chassis)

Data centers are undergoing a major transition to meet higher performance, scalability, and resiliency requirements with fewer resources, smaller footprint, and simplified designs. These rigorous requirements coupled with major data center trends, such as virtualization, data center consolidation  and data growth, are putting a tremendous amount of strain on the existing infrastructure and adding complexity. MDS 9710 is designed to surpass these requirements without a forklift upgrade for the decade ahead.

MDS 9700 provides unprecedented

  • Performance – 24 Tbps Switching capacity
  • Reliability – Redundancy for every critical component in the chassis including Fabric Card
  • Flexibility – Speed, Protocol, DC Architecture

In addition to these unique capabilities MDS 9710 provides the rich feature set and investment protection to customers.

In this series of blogs I plan to focus on design requirements of the next generation DC with MDS 9710.  We will review one aspect of the DC design requirements in each.  Let us look at performance today. A lot of customers how MDS 9710 delivers highest performance today. The performance that application delivers depend

#EngineersUnplugged S5|Ep1: Role and Policy Based Control

We’re back with an all-new season of Engineers Unplugged–more unicorns, more technology, and more selfies than even the Oscars have to offer.

Season 5 kicks off with a bang–role-based access control and policy management discussion brought to you by Nick Howell (@that1guynick) and Joe Onisick (@jonisick). What are the implications for hybrid cloud? What are the predictions for network and storage? How is this related to ACI?

Watch and learn:

Those are some well-maned unicorns, more hair than substance.

#EngineersUnplugged S4|Ep10: Software Defined Hype

In this episode of Engineers Unplugged, Michael Letschin (@mletschin) and Hans De Leenheer (@hansdeleenheer) discuss the history behind software defined and predictions for what the future holds for applications and developers. If hardware is an enabler and not a limit, what then? How does this impact developers? Let’s listen in:

#EngineersUnplugged S4|Ep7: There are no VHS afficianados (storage trends)

In this week’s Engineers Unplugged, Frank Denneman (@FrankDenneman) and Damian Karlson (@sixfootdad) discuss parallels between VHS and traditional storage models, and how all old technology isn’t outdated. This is a great discussion about the role flash storage plays vs array. So be kind, rewind, and let’s dig into the theory behind the evolving storage models:
