Summary: Decoding UCS Invicta Part 2

Solid State Drives (SSD) 101

In part one of this series we covered the internals of HDDs and some basic techniques manufacturers use to increase performance. In part two we are going into a deep dive of Solid State Drives (SSD), how they work, and some caveats.

The solid-state drives (SSDs) have a simple unit where one or more bits are stored: the “NAND Flash Cell”. So, this should be easy! Right! Lets see.

Summary: Decoding UCS Invicta Part 1

Storage 101

Less than a year ago, October 29th 2013, Cisco acquired Whiptail {http://newsroom.cisco.com/release/1279074}, a high performance scalable solid-state memory system. Shortly after its acquisition, the product lines were renamed UCS Invicta.

The idea behind UCS Invicta and its market positioning is application acceleration. This is not to be considered a traditional storage but instead a solution to enhance application performance. In fact, Cisco has made it quite clear that they have no plan to target the traditional storage market:

“This acquisition is really about the server market. It’s a significant opportunity, but distinct from the portion of the market served by traditional stand-alone storage systems. As a result, our continued engagements with NetApp on FlexPod, EMC on VSPEX and VCE on Vblock will not change. We have no current plans to expand into the broad based, traditional storage market.”

Now, just as it happened in 1998 when Cisco got into the VoIP market, and then in 2009 when it got into the server market, we need to learn a new lingo and we need to understand the pains of that market.

In this blog series, I’ll be covering some of the lingo, highlighting some of the pains the users have and describing what UCS Invicta brings to the table. Learn more here.

Summary: High performance Splunk with Vmware on top of EMC ScaleIO and Isilon

I recently did a project involving several moving parts, including Splunk, VMware vSphere, Cisco UCS servers, EMC XtremSF cards, ScaleIO and Isilon. The project goal was to verify the functionality and performance of EMC storage together with Splunk. The results of the project can be applied to a basic physical installation of Splunk, and I added VMware virtualization and scale-out storage to make sure we covered all bases. And I’d now like to share the project results with you, my dear readers. Learn more about it here.

We all start at Square One

June 19, 2014 at 10:00 am PST

I’ve been thinking about what to write for a while now.  I’m involved in some really cool projects right now, pervasive wifi in a theme park, using CMX with many zones at that same theme park and upgrading some public schools to newer equipment with full coverage wifi in the classrooms.  I think each of those would make a great post and I plan to touch on them soon, but this post will be on a comment that an intern made to me while we were upgrading a school recently.  “I can’t believe a Sr. Network Engineer is helping me cable a rack.”  I didn’t think much of it at the time but I did start thinking about it on the way home.
