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.

Not like the site is unlive or something..on the contrary, its beginning to get a lot of attention already. Well most of the work is done, you don't have to worry about anything though:

What won't change

Links/Referrals: I will be redirecting the links (all links which you may have cross-posted) to IdeationCloud.com - so you don't have to do anything in all your posts and links. Although, I would urge however that you do change the permalinks, especially on your blogs etc yourselfThis blog is not going away anywhere but within a few months, I will consider discontinuing its usage. I won't obviously do …

Cloud Security: Eliminate humans from the "Information Supply Chain on the Web"

My upcoming article, part - 3 data center predictions for 2009, has a slideshot talking about the transition from the current age to the cloud computing age to eventually the ideation age- the age where you will have clouds that will emote but they will have no internal employees.

Biggest management disasters occur because internal folks are making a mess of the playground.

Om's blog is carrying an article about Cloud security and it is rather direct but also makes a lot of sense:

I don’t believe that clouds themselves will cause the security breaches and data theft they anticipate; in many ways, clouds will result in better security. Here’s why: Fewer humans –Most computer breaches are the result of human error; only 20-40 percent stem from technical malfunctions. Cloud operators that want to be profitable take humans out of the loop whenever possible.Better tools – Clouds can afford high-end data protection and security monitoring tools, as well as the experts to run them. I trust…
