Managing migration hell with Virtualization

Somewhere near the top of the list of activities that storage people like doing least is data migration. Slow, time-consuming, and often scheduled at convenient times such as 3 a.m. Sunday morning, it has to rank up there with tasks like disaster recovery testing and SAN reconfiguration. To make matters worse, the process often seems to be a prime candidate for Murphy's Law, often exceeding scheduled windows or needing to be rolled back and rescheduled due to unforeseen problems.

The methods used to perform migrations can vary considerably depending on what, where and how much data is being migrated, and in recent years, the number of technology options has increased significantly. In addition to traditional approaches (for example, host-based migration tools and like-to-like storage-array-based replication), a growing trend is toward applying virtualization technologies for data-migration purposes.

Virtualization appliances than sit in the SAN or LAN are one category of the new breed of data-migration tools that are quietly finding a place in environments where data migration is a regularly occurring activity. They can be leveraged to enable transparent data movement without affecting server data access. As a result, service outages are significantly shortened, with downtime only needed for the mounting, cutover and validation of the new storage targets.

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…
