Thoughts on #OpenStack and Software-Defined Storage

May 14, 2014 at 6:18 am PST

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 »

Cisco Domain Ten: Domain 1: Facilities and Infrastructure

December 6, 2012 at 11:22 am PST

Yesterday I introduced you to the Cisco Domain TenSM, Cisco Services’ framework for simplifying data center transformation.  This model is applicable to both business  (enterprise), public sector (e.g. government, federal) and service provider (incl telco) organizations.

Today I will summarize some key challenges that you should consider when planning a transition to cloud (as one example of data center transformation), for Domain #1 -- Facilities and Infrastructure.

What Cisco’s New Data Center Switching Announcements Mean for Service Providers

Cisco’s foundation for delivering the service provider Cloud is our Unified Service Delivery (USD) solution, featuring tightly integrated, data center and IP NGN technologies to deliver a virtualized end-to-end infrastructure for cloud services. We thought it would be useful to share some new capabilities that Cisco has added recently to the solution:

MPLS in the Data Center: To streamline the end to end operation across the data center and IP NGN,  Cisco announced, last week, that Nexus 7000 supports Multi Protocol Label Switching (MPLS) for Layer 3 virtual private networks (VPNs). This allows MPLS to be deployed  at the data center core/aggregation layer  rather than terminating at the data center edge. This capability enables Service Providers to greatly simplify L3 segmentation, especially for multi-tenant cloud offerings, depending on their scale and service needs.

Another key to the delivery of a data center built for Cloud requirements of scale, virtualization and multi-tenancy has been the use of a Unified Fabric. Unified Fabric provides the flexibility of high performance, highly available networks to support the needs of both LAN and SAN on a consolidated fabric. Cisco’s Unified Fabric announcements last week bring new capabilities which extend our already robust offerings to further build out a Service Provider Cloud foundation.
