Yes, it has been quiet around here but…all is well. Changes afoot, as it may be said. So, in the spirit of this newness, let me present a telling screenshot…   Now, what is this all about?! I guess you’ll have to stay tuned to see.
I’ve always had a fascination with the way information is acquired and process. Reading back through the history of this site, you can see this tendency towards more fanciful thinking, e.g. GPGPU assisted network analytics, future storage systems using Torrenza-style processing. What...
So, a big deal was made about a paper from some university researchers somewhere (source here) noting the efficacy of using GPGPUs for Network Analysis (obstensibly as a correlation sieve for all the streams of information being presented).  While this is a GREAT paper, it neglects a f...
Today I’m full of hope.  It’s based around the struggles that our men and women have fought on our behalf, strained for with flesh and blood, given their lives for.  It’s knowing that my freedom isn’t free; that it was paid at a terrible cost, that mothers and f...
I just ripped through some brief interface shots here and compiled it all together.  It sucks but it’ll give you at least a cursory sense for what the Nexus 10 looks like. EDIT: @brandonrbennett pointed out that I forgot to set this in landscape mode. It’s currently being ...
Hey there…this is a quick ‘n dirty post on the Google/Samsung Nexus 10 tablet.  I’ve been asked by a few folks to provide my first impressions of the tablet and so, here it goes.  For what it’s worth, I HATE unboxing videos so, I’m not going to stoop to th...
August has been exceptionally busy @ Juniper and soon, I’ll be starting to lay out some of the work I’ve been doing in public.  Until that point, however, you’ll have to “suffer” through the ongoing process that is my desk.  To that end, I’ve got a c...
As I’ve written previously (here, for those who need the reference), I’m in the process of building a desk (or desk system) using some rough cut planks of butternut (aka white walnut).  The beauty of this process is the fact that I get to choose my finishes and work through...
As some of you may or may not know (check Twitter if you don’t), I’m in the process of building a desk system.  I loved the look and function of Ikea‘s Galant desk system but wanted something a bit more organic in nature.  Consequently, I went on the hunt for some dif...
more later, but trust me…this is FANTASTIC! image (c) by SwitchLightingco.com; used by permission
Since I’ve made a few public promises (on Twitter, no less) stating that I’d actually post something by the end of the year (2011; last post was in June 2011), I’ve decided to actually KEEP that promise.  To that end, here’s my quick ‘n dirty post for the ...
One benefit of being gainfully under-employed is having those brief bursts of inspiration that allow you to get on paper (or blog) those streaming bits of ideas that could change your destiny.  Perhaps there’s a bit of hyperbole worked in there (ok, a whole lot) but the fact rema...
This morning, Dave Cahill (@dcahill8) posted a rather in-depth look at Carbonite and provided a counter to their business model by including Dropbox.  While Dave is a conservative guy, I’m really not, so, I took the challenge to hopefully expound upon what I think is Dropbox̵...
Since it’s been roughly (i don’t know) several months since i last wrote (and yes, i’m doing the e.e. cummings thing by only using lower case letters), i decided it was time to motivate the sedentary gray matter between my ears and actually put finger to keyboard to&#...
I know, I know.  This post isn’t about my work @ Cirtas Systems nor is it about the fundamental shift in storage technologies away from on-premise to cloud. Rather, it’s about the adventures I’ve had since getting my iPhone and attempting to make it a worthwhile repla...
So, it appears that I’ve been relatively successful in casting some level of intrigue around where I’m going after EMC. I’ve heard everything from VMware to Acadia to heaven-knows-what and while each of these companies are AWESOME for what they do, they’re not ...
After 3.5 years at EMC, I’ve decided it’s time for a change. During my time at EMC, I’ve been able to participate in some really cool stuff (Atmos, V-Max, CX4, some upcoming technologies you’ll be sure to hear about, etc.) and really felt valued both as an emplo...
Contrary to what it appears, I’m actually alive (and typing this from the Blogger’s Lounge @ EMC World 2010)… Been a busy month or so and lots of stuff going on (that I can/can’t talk about) so, i’ll keep this post brief. Suffice it to say, I’m here,...
I love receiving suprise packages. Way back in January, I got a briefing on a VERY cool server offering from Dell that was going to be part of their DCS (Dell Cloud Services) offering. I, of course, requested one understanding it to be an almost perfect density compute node for my ...
Image via Wikipedia Just a quick note from the field (as it were).  If you’ve been blessed enough to get a Cisco C-series server, there’s a nifty new Cisco Integrated Management Controller (CIMC) release available as of today’s writing. Version 1.0(1e) was the ship...
Since quite a few folks asked for some more detail on EMC Atmos GeoProtect and the underlying erasure coding, we prepared a YouTube video overview. GeoProtect and Erasure Coding Enjoy! Related articles by Zemanta EMC adds awesome to Atmos (go.theregister.com)
Image via Wikipedia It’s a rather dark and snowy Tuesday in Hopkinton today but, despite the craptastic weather, there’s some good news floating about.  EMC’s Cloud Infrastructure Group has released Atmos version 1.3 which is a significant overhaul of the Atmos cod...
Image via Wikipedia I finally received some new servers in the Atmos lab and…well, I thought I’d share with you!!!  These are Cisco C200 M1 servers and they’re loaded out in the following config: Processors:  Intel Xeon 5520 (2.27Ghz quad cores w/Hyperthreading) Me...
Just was getting some thoughts out about using GPGPUs (nVidia’s Tesla and Fermi products, ATI’s FireStream) for handling some of the menial cloud-based operations (metadata calc, metadata location servicing, offload, etc.) that we have as part of any type of cloud file syst...
I figured I’d start the year off right and give all of you a bit of an overview on the Dell R610 hardware that I use in my test and development work.  Got 6 of these guys in the other day so, I shot a quick video overview of the hardware and specs for you [...]
I thought this might be a good way to start off 2010.  So, what are you considering for your 10 gigabit infrastructure overhaul? Feel free to comment below!
Ok, ok….I know I should actually write stuff out from time to time, but, seriously, the Flip UltraHD makes this waaaay too easy… In any case, here’s a quick (11 minutes…sorry…) video with my DataCenter wish list….(some of these items have already bee...
This is a tongue in cheek video that I took in one of my labs showing why, for no other reason but fabric reduction, that CEE/DCE/FCoE is a valuable thing for ANY IT infrastructure. A couple of things you'll notice here are: a.) it’s loud. Sorry about that…this lab is in ...
Image via Wikipedia I was advised the other day that a certain manufacturer was adopting a rather interesting model for Fibre Channel over Ethernet CNA licensing.  Rather than simply purchasing a FCoE CNA with all the features (10GbE, iSCSI, and FCoE) turned on, they were going to a...
If you follow me on Twitter at all, you’ll know that I’m a big fan of Qlogic. I appreciate the functional simplicity of what Qlogic designs encompass as well as the “get business done” attitude that they bring to their switches, HBAs, NICs, and CNAs. Imagine my happiness, then, when I...
In my first post on policy, I tried to show what policy's influence would be like from a top-level standpoint. We see that policy can start from a localized array standpoint and "fix" performance or hotspot issues based on key LUN migration technologies (like EMC's FAST promises to d...
As many of you may know, I work for EMC’s Cloud Infrastructure Group as part of the Atmos solution team. In this role, I’ve been blessed with getting a closer look at where the future of cloud storage is going as well as some of the drivers that will get it there. In [......
This was filmed Wednesday, September 2nd. Enjoy!
Yup, I’m at it again.  This tech minute recording was taken yesterday (September 1) and features the wonderful talents of Chad Sakac and Chris Hoff!  Enjoy!
Just a video from the Cisco Tech Minute filmed on Monday, August 31.  Enjoy!
One of the principle points of contention within the cloud storage space is what to do with metadata (literally: “data about data”).  There are several schools of thought regarding how metadata should be presented, protected and optimized but for the sake of this post, I...
I’ve been ruminating on a conversation that I was part of at the recent Cloud Camp – Boston “un-conference.”  In this particular case, a customer (a VAR; NOT a manufacturer) was talking about leveraging cloud storage for a particular customer of theirs who had t...
Going along with the Cloud theme that I’m fortunate enough to be a part of, I’ve decided to use the “micro-burst” moniker to section off quick n’ dirty posts on a variety of cloud subjects that I don’t have time to dive into fully.  With that in mind...
Well folks, it’s been fun being your “EMC Technical Consultant on the Interweb.” (there are more of us, trust me. ) It is with great happiness, however, that I get to report that I’m moving over to what has to be the most exciting innovation within EMC in the ...
So, after a few days of beating around this problem, I’ve come to the conclusion that either I’m a complete Linux tool (likely) or there is something fundamentally wrong with FUSE 2.7.4 and CentOS 5.3 (x86-64 edition). (FUSE = Filesytem in User Space) To that end, I’...
