Seagate recently introduced technology preview of their latest invention, and desire of plenty of people, Ethernet drive interface. I always desired this to be reality since plenty of people are just hating necessity of usage traditional file systems due to their mutual incompatibility and danger it may pose to one’s data.
Much of people even today’s modern world of technology do not understand the need for tens of different file system formats, their good and bad sides and whether one is better over other for their particular need. Well this is about to end soon once serial production of this new interface starts. Thing is that cloud service providers will profit the most. Read on..

[This is not really about the Red Sox or pumpkins this Halloween, but how could I not use those in the title? Go Red Sox]
I left an awful teaser at the end of my article last week. In Brent Salisbury’s original article that triggered some of these additional virtualization thoughts, he articulated two very clear differences between native network based L2 virtualization mechanisms and the mechanisms that are being provided by overlay solutions based mostly in server vSwitch infrastructure. These two fundamental functions are MAC learning and tunnel encapsulation. In today’s post I will spend a little more time looking at encapsulation differences.

With storage needs in your organizations growing exponentially over the last few years and into the future there are plenty of things you may done in the past to help keep the cost down. Chances are you bought some kind of fancy SAN, that had all the bells and whistles to help storage work efficiently. I am willing to bet one of the features your SAN has is data de-duplication.
With Windows Server 2012 we introduced built-in data de-duplication on a per-volume basis. You can save a tremendous amount in storage costs with this powerful addition. Thisde-duplication feature uses data broken into chunks and eliminates duplicates while adding pointers and using advanced mechanisms to provide for and prevent potential data loss. The de-duplication feature also uses a data aging system to ensure that only data that is resident on the volume for greater than 4 days (4 is the default and is adjustable based on your own situation) is de-duplicated to prevent the de-duplication of data that is constantly changing. If you want to take a look at a fantastic example take a look at post from a previous series which shows a de-deplicaiton from 240GB to 7GB:

Exposing an API to your application is as risky as installing a doggie door into your house—as a recent incident with a bear aptly illustrates.
Exposing an API to your application is as risky as installing a doggie door into your house: you expect your dog to have the convenience of outdoor access, but the reality is that you cut a hole in your house.
The intended use is to give the anticipated “users” access to an area that is otherwise private. However, once you open that portal into your sanctuary, there’s no telling who else might take advantage of it. Just as the doggie door can open your home to all sorts of wildlife, so can API exposure open the door to application usage you never anticipated (both innocent misuse and malicious attacks).

A little while ago I wrote about the differences between routing and switching, or probably more the difference between ethernet and IP forwarding. Then focus of that article was very much on the differences between the two from a forwarding hardware perspective. This article last week from Brent Salisbury triggered a bunch of additional thoughts around scale and size.
As some sense of disclosure, in my previous job at Nortel/Avaya I was part of the team that pushed Shortest Path Bridging (SPB) spearheaded by Paul Unbehagen. I am a fan of SPB, I believe it is an extremely well thought out mechanism to provide network based virtualized ethernet networks with many real life practical roots in the learnings from MPLS and early more static solutions like PBB and PBT.

A leading telcom’s testing efforts were regularly delayed & cut short due to test environment access constraints. Learn how service virtualization helped.
To accelerate application release cycles, KPN needed to address a critical bottleneck in the testing process. Their end-to-end test scenarios interacted with dependencies controlled by other divisions and external entities, and gaining access to the required dependencies was a slow and frustrating process. Due to these test environment access constraints, testing efforts were regularly delayed and cut short.

It’s common enough to be expected, but the IT world is continually undergoing all kinds of restructuring, remodeling and rethinking when it comes to approaching day-to-day tasks and challenges, both typical and atypical. A requirement of today’s IT professional is to not only be fully acquainted with the current operating systems, software and processes, but also to be prepared for the big changes to come, as new updates, patches and strategies arrive. The arrival of cloud computing, BYOD and virtual desktops have led to many established standards being overthrown for these more beneficial and efficient ones.
