File Virtualization: NetApp's VFM does DoD Migration

The Defense Contract Management Agency (DCMA) is the Department of Defense's contract manager, its 10,000 employees overseeing 300,000 prime contracts worth a total of $850 billion. It is responsible for seeing that those contracts meet the performance requirements and deadlines, while coming within budget. But it also has to make sure it is spending its own budget wisely, which led to the data center consolidation.

The project involved several actions. One was to reduce the number of servers by using VMware's Infrastructure. The DCMA began looking at virtualization in mid-2005. At that point, the agency had about 625 servers, and was replacing 200 of them annually. In November of that year, it started using VMware virtualization technology, buying 60 new servers instead of the usual 200. In subsequent years, it only needs to buy 20, saving the agency nearly half a million dollars annually, not counting power, cooling and labor costs. Earlier this year, the DCMA upgraded to the latest version – VMware Infrastructure 3 – which virtualizes servers, storage and networking.

In addition to consolidating the servers, the DCMA also needed to set up a common file system that would work across the enterprise. For this it created a File Area Network (FAN) using software and storage appliances from Network Appliance. The DCMA has over 300TB of storage.

When it consolidated its data centers, the agency went from 56 file and print servers down to two clustered NetApp Filers – the FAS3020C and FAS6070C – at each site: the DCMA's primary data center in Carson and another in Boston. The 3020Cs are used for file sharing and the 6070Cs are in a SAN. NetApp’s VFM was used to migrate the files from the file servers to the NetApp appliances.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…

Redhot Future Of IT Part 2 :Virtualized Workplaces

Click on the title to hear what I have to say, alternatively click here to listen to what I have to say here.

So what is a virtualized workplace? Does it mean it does not exist? That it's virtual? Well in a certain way YES. This is where the future of our workplace is going to be. Well it is already a reality in some countries.

OK lets start by asking ourselves these questions:
Do you really bond with your colleagues? (think Team cohesiveness)
Do you spend great amount of hours talking about great things that you will do together? (think collaboration)
Do you really feel that you give 100% at work? (think effectiveness)
What do you really miss at your desk? (think personalization)
Is your desk comfortable enough? (Again think optimizing personalization, OK you have done your best to make it your place)Does it really matter to your employer that you are there for him/her? (think commitment)
Or do you get micromanaged over petty issues? (think mismanagement)
Do you see your employees perfor…

A Collection of Threnodies : Part 1

Whale Fall

Dress me up in my new threads
clasp my greasy palms
grease my hair
I'm ready for the fall

Watch at all the decadence
watching the avalanche
I'm slipping down
losing my buoyancy

What's become of us
where have we come
this far, this close
close to the doors

I hear them, sublimal chants
I'm on the run
I race through the human sea
I am the king!

I'm the slave
to my own undoings
I'm the jester in my courtyard
We jest as we run

We're strolling on that thin rope
we grope as we rope
we're true heros
we're the survivors

we're the scavengers
we're the friends
we're the lovers
we're the unbred

Soon awaiting the fall
we're lurking on us
we're osedaxing us
we're soon going to be done
we'll soon be arrested

*osedax(bone devourer, newly discovered marine genus) feeds on a fallen(sunken) whale carcass(which is also called a whale fall). Read more here
