It's easy to understand why server virtualization has become so popular among IT admins. Virtual servers are flexible, mobile and can be deployed or decommissioned rapidly. However, managing storage for virtual environments can be difficult. Many shops struggle with managing storage for virtual servers, and even more could realize better performance with more sophisticated management. Storage management tools for virtual environments can capture and record data from hypervisors; extend visibility into storage, network and applications; and provide trending analysis to help keep resources in balance. These tools can help you take a proactive approach to storage management, reduce costs and improve performance.
RAID has formed the backbone of local data availability for nearly 30 years, but the technology is starting to show its age, and erasure coding has emerged as an alternative. Some even say it could even eliminate the need for traditional data backup.
Storage and backup administrators are a tough crowd. So it means something when users of Asigra and Veeam backup products return the two vendors to the winner's circle in a reprise of last year's Backup Software Quality Awards results.

Evaluate RAID Vendors & Products
Weigh the pros and cons of technologies, products and projects you are considering.
Storage virtualization can come in a number of different forms. Some might consider storage virtualization as software that acts as a control layer to pool capacity from multiple, different vendors. Others might include the several types of products that fall under the software-defined storage category in their definition of storage virtualization. Some would even argue that storage arrays that come equipped with features such as RAID or thin provisioning provide some of the same benefits of storage virtualization. Regardless of the chosen method, there are some common goals that storage virtualization can achieve -- greater scalability and more efficient management are high on that list. But when pairing storage virtualization with server virtualization, the picture gets a little less clear. Conflicting virtualization layers can waste resources if one abstraction layer masks the features of the other. Furthermore, it's possible for management to get murky if there are separate control panels for separate virtualization layers -- and that can make monitoring and troubleshooting that much more difficult. This E-book provides an overview of the most common storage virtualization technologies available today and the benefits and drawbacks of each. It will also provide a series of best practices for storage administrators who are considering the use of a storage virtualization product in their virtual server environment. Continue Reading
