As our reliance on effective data centers continues to grow, we run into more and more issues that must be addressed to ensure security and availability. We've been turning to virtualization solutions for some time now, and many organizations have come to believe that it is the cure-all that will save them money and reduce the level of complexity. However, virtualization isn't a plug-n-play kind of thing. You can't just set it and forget it, because if it isn't done exactly right, you will only shift the costs and complexities rather than eliminate them.
In order to get the most value out of the data center, it is important to understand the challenges and implement the associated best practices. As the number of business applications and volume of data continues to increase, data centers need solutions like virtualization to remain profitable - but simply installing the solution isn't enough. You need to make sure that everything you do will contribute to a more efficient and effective organization.
1. Know Your Environment Beforehand
You need to have a clear understanding of your IT assets and how they are used within the organization. It is equally important to track who is using them and how often. Take the time to research the server activity and get the hard numbers related to its usage. Anecdotal evidence that the "servers are running slowly" isn't good enough to turn to virtualization. Track usage statistics and you won't have to buy servers and storage devices that you don't actually need. For more tips like these, visit dell.com.
2. Double-Check Hardware Compatibility
Your hardware and virtualization software must be completely compatible to ensure an effective transition. If there are components that don't work with your software, or if some of them simply don't run fast enough anymore, you may create bottlenecks or failures in the system. Double-check everything (including mobile devices) for compatibility before you start installing the new solution.
Virtualization opens the door to a lot of unproductive elements. Virtual machine proliferation can be a serious problem because there are several hypervisors that are completely free and it's so easy to just clone a guest. This can increase security problems and make the entire system harder to manage. The key is to standardize processes, centralize storage, and make sure the entire organization understands the necessary requirements and adheres strictly to them.
4. Virtualization Training
While it is true that virtualization has become very common in many industries, it is still a new concept to many organizations. Take the time to make sure the staff is properly trained on the new systems and understand exactly what virtualization means to the company. Set goals for performance, learn to prioritize management and patching updates, and learn the difference between bottlenecks and different system roles.
5. Backup and Backup Again
In some ways, virtual servers still need to be treated like their physical counterparts. This is to say that any data on them is just as vulnerable to harmful events that could destroy or otherwise make it inaccessible. Recovery measures are extremely important in virtualization, and you can back up the entire virtual machine or just the data. Either way, make sure that it is done on a regular basis.

Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and...

Application transformation and DevOps practices are two sides of the same coin. Enterprises that want to capture value faster, need to deliver value faster – time value of money principle. To do that enterprises need to build cloud-native apps as microservices by empowering teams to build, ship, and run in production. In his session at @DevOpsSummit at 19th Cloud Expo, Neil Gehani, senior product manager at HPE, discussed what every business should plan for how to structure their teams to delive...

DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

IT leaders face a monumental challenge. They must figure out how to sort through the cacophony of new technologies, buzzwords, and industry hype to find the right digital path forward for their organizations. And they simply cannot afford to fail. Those organizations that are fastest to the right digital path will be the ones that win. The path forward, however, is strewn with the legacy of decisions made long ago — often before any of the current leadership team assumed their roles. While it’s ...

As we enter the final week before the 19th International Cloud Expo | @ThingsExpo in Santa Clara, CA, it's time for me to reflect on six big topics that will be important during the show. Hybrid Cloud: This general-purpose term seems to provide a comfort zone for many enterprise IT managers. It sounds reassuring to be able to work with one of the major public-cloud providers like AWS or Microsoft Azure while still maintaining an on-site presence.

Between 2005 and 2020, data volumes will grow by a factor of 300 – enough data to stack CDs from the earth to the moon 162 times. This has come to be known as the ‘big data’ phenomenon. Unfortunately, traditional approaches to handling, storing and analyzing data aren’t adequate at this scale: they’re too costly, slow and physically cumbersome to keep up. Fortunately, in response a new breed of technology has emerged that is cheaper, faster and more scalable. Yet, in meeting these new needs they...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
