Storage management: efficiently using and saving energy



Storage vendor 3Par maintains that in one instance, it found a large customer's existing OLTP systems to be only 8% utilized--the other 92% was just adding entropy to the universe. While this is an extreme example, it illustrates the point. Good storage management can save a lot of money, space, and power.

For OLTP that means thin provisioning, a technique that allocates disk blocks to a given application only when the blocks are actually written rather than at initial provisioning. By employing thin provisioning along with good storage management software, the onus for guessing exactly how much storage will be needed is taken off the database administrator and instead can be tracked by the storage management system itself. A year ago, only a few vendors were offering thin provisioning on OLTP systems; now it's much more pervasive and should be strongly considered to right-size OLTP storage.

For general-purpose file storage, the problem is much different. Thin provisioning is useful here, too, but more commonly the problem comes down to creating a global view of all data stored across disparate systems. After all, just how many copies of the latest Paris Hilton video does an enterprise need (or copies of the annual report, or the video of the CEO's address to shareholders, and so on)? Global storage resource management (SRM) systems are the best bet for understanding and managing the complex storage needs of an enterprise.

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…
