New sponsor: Digeus SnapIT Screen Capture

I've a new sponsor for my blog: it's Digeus Inc. that develops plenty of applications for different usages
I've been asked to try out the SnapIT Screen Capture (current release 3.7).
The application is easy to use screen capture software which allows you to easily capture anything on the screen including windows, menus, full screen, rectangular regions,web pages and take shots of moving images.

  • - Supports hotkeys, auto-saving, clipboard
  • - Automatically copies screenshots to the clipboard
  • - Tracks capture history, auto-saves captured images
  • - Saves files in BMP, GIF, JPEG, PNG and TIFF formats
  • - Auto-names captured images

you can download a trial copy of SnapIT Screen Capture and get a fully functional code for the software from Digeus Inc. if you write a brief review of the application on your blog. (first 10 that send me the link to the review)

VCAP5 podacast: upgrade path?

In vExperienced.co.uk blog Edward Grigson puts an interestin reference to a vmware community podcast about VCAP5 exams.
There will be an expedited path for those with VCAP4certifications BUT they will be similar to the VCP upgrade in that it’ll be a time limited offer. He didn’t specify exactly what form this would take but with the VCP upgrade you have roughly six months to take the new exam with no course prerequisites. I’m guessing you’ll have a similar period where the VCP5 prerequisite doesn’t apply.

... Forget to mention... Important for VCP5 test takers

Hello all,
In my previous post I forget to mention a really useful blog for whoever is studying for VCP5.
The site is www.vreference.com and there you can find the famous vSphere 5.0 vReference Card. It’s provided as an A4 download and a Letter Download.

They are provided by Forbes Guthrie (@forbesguthrie) author of the VMware vSphere Design book that I use to prepare the VCAP-DCD410 exam.

Moreover on the site you can find the condensed notes for the vSphere 5.0 documentation.

All those materials are part of the diligent VCP5 test taker :) .

VMware's New Graphics Architecture Is Shaping Up

Michael Larabel write a post on Phoronix site telling us about VMware graphics architecture achivement.
VMware's overhauled Linux graphics driver stack is shaping up and coming together nicely in time for Ubuntu 12.04 LTS, which will allow for 2D/3D guest acceleration within virtualized guest machines.

VMware Deployment Guide For ArcGIS Server Updated For Version 10 With Performance Results

Good article on deploying ArcGIS on Vmware by

A couple years ago VMware published a comprehensive deployment guide for ArcGIS Server 9.3. This guide focused on deployment and contained a number of technical considerations that one should take into account during an ArcGIS Server deployment.

VMware has now updated this guide for ArcGIS Server 10.

Test passed: now I'm VCP5



Hello all,
passed my VCP510 test exam, one month after the VCAP-DCD410.
Hints for passing the exam:

- read blogs and communities posts
- play around with an home lab if you don't have a lab at work

add some (e)books and online training courses: both the below reading were helpful to me
- "VmWare vSphere 5 Clustering Technical deepdive" by Duncan Epping (@DuncanYB) and Frank Denneman
- "VMware vSphere 5 Administration Instant Reference" by Christopher Kusek (@cxi) and al.

There is also a vSphere 5 training series by TrainSignal which is excellent especially if you are new to virtualisation and vSphere 5 is your first step into the world of cloud computing.

New Year Resolution: new home vSphere lab


Hello all,
the beginning of the year is time of changes. Reading the blog post on Boerlowie I come to the conclusion that's the moment for changing my home #vSphere lab environment.
I will probably go with the below configuration, but all hints are welcome:
Base system:
  • Asus P8Z68-V motherboard (anyone know if there is a dual socket affordable MB?)
  • Intel Core i7-2600 3,4 GHz
  • 4 x Kingston 4GB DDR3-1333 PC3-10666 Unbuffered OR Corsair Vengeance Low Profile DDR3 PC3-12800 Blue - Kit 16GB (4 x 4 GB)
  • OCZ Vertex 3 MAX IOPS Edition SATA III SSD 2.5 - 120 GB

if I found 4 x 8 GB kit for RAM I will go for that.

Then I've got some spare internal disks for keeping all the (ISOs, templates, and VMs that do not need maximum performances).

I'm trying to get an #Iomega #StorCenter IX2-200 NAS or a #Drobo but the prices are still high for an home lab: friends from #iomega #emc #drobo have you got some spare used NAS to sell me? Contact me @mfrizzi!

As stated above hints are very welcome!

cheers

Cloud contest on Cloud-Buddy: ... and the winner is...

Hello all,
the Cloud computing definition on Cloud-buddy.com is over.
I'm pleased to announce that the winner is... me
Here's my definition of cloud computing and the impact that I think cloud computing will have on IT:

Clouds are invisible masses of resources made of CPU cycles, MHz, GBytes of RAM, IOPS, Network throughtput, resources pools and VLANs, “suspended” in datacenters on the the surface of the planet.

A Cloud gets triggered by requests of services, possibly acting together, and “precipitation” of resources above will “fall” on the requesters.

Clouds come in different flavors:
- the-cloud-is-mine-and-I-use-it (aka private Cloud)
- the-cloud-is-mine-with-a-little-help-of-your-cloud (aka hybrid Cloud)
- the-cloud-is-your-and-everyone-can-use-it (aka public Cloud)
Each flavor depends on who can trigger the Cloud by requesting its services and where the Cloud will “precipitates” its “rain of resources”.

The dimension of the Cloud and the sizing of its “resources pools” can produce light, moderate or heavy “precipitation”.

A “well formed” Cloud shoud have “sister Cloud” living in the same campus or “suspended” somewhere on the surface of the planet, ready to “precipitate” the needed “rain of resources” , just in case the primary Cloud “evaporates”.

Cloud computing will impact IT world by introducing new processes to manage the internal computing resources and to expand them on demand leveraging on cloud services provider. Automation will be the key
More powerful and granular Chargeback products for pay per use services will spring out in the IT world
Moreover cloud computing will force Telco services providers to invest in more reliable and less latency connectivity to leverage cloud computing features.

Finally :) virtualization design architects will became “weather forecasters” (to create a well formed Cloud, you need to know where and how much “rain of resources” will be requested).

I would like to thank Bilal Hashmi (@hashmibilal) for creating the contest and many thank to Christopher Kusek (@cxi) , Duncan Epping (@duncanyb) and John Mark Troyer (@jtroyer) who made all this possible sponsoring it.

RTFM-ED: New SRM book from Mike Laverick


Hello all,
Mike Laverick announced the availability of his new book "Administering VMware Site Recovery Manager 5.0" on his site rtfm-ed.co.uk

[...] I’m pleased to say that my new book on SRM 5.0 has been released on the VMware Press. It’s one of the first books on the press which VMware has founded with the logistical help of Pearson Publishing. I started working with the very early betas of the product towards the end of last 2010, so for me this work has been really years worth of work. I originally started out with self-publishing the SRM books, and its great to finally have big company like VMware and Pearson behind the work. [...]

Great post on EMC Avamar from Mikes.eu blog

I've found this interesting post on EMC Avamar
EMC Avamar is a sourcebase global deduplication solution which enables fast, efficient backup and recovery by reducing the size of backup data at the client before it is transferred across the network and stored. Avamar’s data deduplication dramatically reduces network traffic by only sending unique blocks over LAN/WAN. Blocks that were previously stored are never backed up again.
