Hu Yoshida: Virtualization is about lying

Eric Hibbard, the plain speaking Chair of the SNIA Security Technical Work Group, often says that Virtualization is about lying and security is about understanding the truth. I prefer to say that virtualization simplifies management and improves efficiency by masking the underlying physical complexity.

Eric also makes the point that if you are going to lie, you better be in position to know the truth as well. I whole heartedly agree with him there. That is why it is important to do your storage virtualization where you are also working with the truth and the only place to do that is in the storage control unit, not in the storage network. If you are virtualizing storage in the storage network, creating virtual volumes with mapping tables, while the real volumes, cache slots and track tables reside in the storage array, you have a disconnect and a potential for a security disaster, i.e., the loss or compromise of data..



Well we can say that about everything in life. Our lives on this planet too is a lie. We just happen to inhabit this piece of rock which is part of the 200,000 billion star-systems (or solar systems).

OK, my point is: You CAN lie about virtualization and you CAN blame everything on everything else, BUT you have to understand one thing: Not only you must know and understand the truth, but the fact the person you are lying to, will find out the truth.

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…
