Managing storage for virtual environments: A complete guide
Explore the top tips and tools for virtual server storage management and get hypervisor-specific management advice.
Introduction
Managing storage for virtual environments can be a difficult task. Virtualizing servers requires storage administrators to understand both the storage and the virtualization infrastructure. Furthermore, virtualization randomizes sequential I/O, which can cause a lag in performance. This makes the ability to properly size storage and report storage statistics for virtual environments critical to the efficiency of the infrastructure.
Performance monitoring, for example, can help administrators pinpoint the location of a host of problems, while using the right management tools for aspects such as capacity planning can help alleviate those pain points before they even happen. Meanwhile, best practices for managing storage in virtual environments can vary depending on the hypervisor, many of which have their own built-in management capabilities.
There is also storage hardware and software technology still new to the market that aims to make management of virtual server environments even easier. Products like VM-aware storage are built specifically to close the gap between the storage and hypervisor, while hyper-converged infrastructures ease installation by packaging the hypervisor and storage in one box.
To help you determine the best way to proceed with data storage management in your virtual environment, we've compiled some best practices, including an overview of storage technologies for VMs, top storage management tools and advice based on an environment's hypervisor type.
1Tech overview-
Storage technology options for VMs
Today's storage vendors recognize the unique provisioning and performance challenges that virtualizing servers puts on storage systems. And that means administrators no longer need to stick with a traditional SAN or NAS to satisfy those requirements. Technologies such as VM-aware storage and converged infrastructures are examples of storage for virtual environments today that make integration and performance less problematic for administrators.

3Tools-
Top tools for virtual server storage management
When it comes to storage capacity and performance in virtual environments, storage administrators have a number of choices available to them. Some tools, such as those for automated tiering or deduplication, might be built into the storage itself and can help maintain top-notch performance. And there are third-party vendor tools that can provide reports on a per-VM basis. The links below provide examples of some of the most helpful tools available from a variety of vendors.
