The Live Webcast with NetApp and Kingman Tang went quite well with good discussion on private cloud and data center stacks. Check out the recording below.

Why NetApp is my ‘A-Game’ Storage Architecture
One of, if not the, most popular of my blog posts to date has been ‘Why Cisco UCS is my ‘A-Game’ Server Architecture (http://www.definethecloud.net/why-cisco-ucs-is-my-a-game-server-architecture.) In that post I describe why I lead with Cisco UCS for most consultative engagements. This follow up for storage has been a long time coming,…
Redundancy in Data Storage: Part 2: Geographical Replication
This is a followup to my previous article, Redundancy in Data Storage: Part 1: RAID Levels, where I discussed various site-local data redundancy technologies. Here, I will attempt to detail many of the choices available to provide redundancy beyond the data center that organizations use to solve disaster recovery, business…
OTV and Vplex: Plumbing for Disaster Avoidance
High availability, disaster recovery, business continuity, etc. are all key concerns of any data center design. They all describe separate components of the big concept: ‘When something does go wrong how do I keep doing business.’ Very public real world disasters have taught us as an industry valuable lessons in…

Cisco unified Computing System (UCS) High-Level Overview
I’ve been looking for tools to supplement Power Point, Whiteboard, etc. and Brian Gracely (@bgracely) suggested I try Prezi (www.prezi.com.) Prezi is a very slick tool for non-slide based presentations.  I don’t think it will replace slides or white board for me, but it’s a great supplement. It’s got a…
Inter-Fabric Traffic in UCS–Part II
In the first part of this post (http://www.definethecloud.net/inter-fabric-traffic-in-ucs) I discuss server traffic flows within a UCS system focusing on End-Host mode (EH mode.) EH mode is the default and recommended mode for the majority of UCS implementations, but the system can also be used in ‘Switch mode’ which causes the…
An End User’s Cloud Security Question
I recently received an email with a question about the security of cloud computing environments. The question comes from a knowledgeable user and boils down to ‘Isn’t my data safer on my systems?’ I thought this would be a great question to open up to the wider community. Does anyone…
Redundancy in Data Storage: Part 1: RAID Levels
I recently read Joe Onisick’s piece, “Have We Taken Data Redundancy Too Far?â€Â I think Joe raises a good point, and this is a natural topic to dissect in detail after my previous article about cloud disaster recovery and business continuity. I, too, am concerned by the variety of data…
Cisco Unified Computing System Value: A Customer’s Perspective
For those who do not know me, I’ve been blogging since April 2010. My primary subject has been Cisco UCS and everything around it. Now, when I say “everything around itâ€, I really mean “everything around it as it pertains to my organizationâ€. If you want to read a lot,…
