When vSphere 6.0 came out earlier this year, there was a lot of hubbub about one feature in particular, and rightfully so. VVols, or virtual volumes, are a way to virtualize storage arrays and have them dynamically move and configure alongside your virtual machines.
VVols don’t replace traditional virtual storage methods, so you can keep using your existing storage strategies and hardware along with VVols. Basically, no matter what kind of storage you’re using in the data center, vSphere treats it as a datastore logical object. Previously, each time you needed to configure a VM for performance or availability, you’d have to move it to a different datastore.
Read on to learn why virtualized storage is way cool, and for some reasons you might not want to dive in just yet.
IT certifications have been around for ages. They can help IT professionals boost their resume and keep their skills sharp. The community is often split on the benefits of cloud certifications, however, with some finding them worthwhile and others arguing that cloud is too broad of a category, with too many competing vendors and platforms for certifications to be valuable.
IT certifications have always been vendor-driven, however, and if you expect to work with a specific vendor’s tools, a certification can be one way to help you secure a position or provide better service to your company’s clients. If you’re a Managed Service Provider (MSP) or cloud channel partner, a certification might help you get more business, too.
What are the main pros and cons of getting cloud certified?
As Director of Engineering and Operations at Green House Data, Mike Mazarakis has helped his share of companies migrate to the cloud. With 20 years of data center and networking experience, he's a self-described “pragmatist in IT” who has watched virtualization evolve into the concept of cloud we all know today.
Mike answered questions submitted by the public in a webcast last month. We interviewed him to get the answers to the most pressing cloud migration questions and help you plan your move to hosted IT. Look for more features in our cloud migration series in the coming weeks.
After the jump, learn how small businesses and enterprises differ in their approach to the cloud, read a walkthrough of one company's quest to move to the cloud while continuing to use existing IT assets, and see the three primary types of new cloud users—plus more!
Even if in-house enterprise data centers are shockingly inefficient (as IDC recently discovered) most data center designers and operators are looking to reduce their energy consumption, as it’s one of the biggest IT expenses. Budgets are tight, so large retrofits or new builds are often out of the question.
To increase energy efficiency and add the bonus of a lower carbon footprint, IT executives should perform a complete power consumption evaluation and then check out each of the following five areas of the data center.
It's been nearly a year since we've done a blog roundup, but if you follow Green House Data on Twitter or LinkedIn, you know we stay tuned to the latest data center, networking, and green energy news. In case you missed it, last month brought out headlines on inefficient in-house enterprise data centers, security and shadow app use, tips for vSphere data center design, and a debate over Greenpeace's report on green data centers. According to our Twitter stats, readers found the following articles the most interesting last month.
