Server virtualization increases the complexity of storage management and forces administrators to pay even closer attention to issues such as available bandwidth and overprovisioning. Approaching management and provisioning in the same way as in a traditional environment could be an invitation for poor performance, wasted capacity and risky data protection techniques. Each of the major server virtualization vendors takes a slightly different approach to storage management and configuration, which might dictate aspects such as recommended protocols, feature sets and data protection schemes. But in addition to this, storage administrators must be sure to construct storage architectures based on different requirements than what they might architect in a traditional, non-virtualized environment. They need to provide an increased level of performance because virtualization multiplexes data that was once sequential together, making it more difficult to read and write. Providing fault tolerance against hardware failures is also essential to keeping virtual machines (VMs) and their applications up and running. The VM storage also must commonly support either multi-path connectivity or storage replication so that running VMs can be moved between host servers on an as-needed basis with little to no downtime. This e-book will help storage administrators plan for these requirements before architecting storage for their virtual environments. Continue Reading

Evaluate Thin provisioning Vendors & Products
Weigh the pros and cons of technologies, products and projects you are considering.
Even though virtualization has become commonplace in today's data centers, provisioning storage for applications on virtual machines (VMs) often remains a pain point for IT professionals. Random I/O processes unique to virtual environments often put a strain on storage hardware and it's common for one, or even several, VMs to eat up bandwidth, leaving others without the power they need. In addition, configuring logical unit numbers and volumes when provisioning storage for virtual environments can be extremely complicated.
Today, vendors of emerging storage technologies are attempting to pave a smoother path toward better performance and capacity in virtual environments. Technologies such as hyper-converged storage aim to create a simpler configuration by shipping the hypervisor and storage in one box. Other products, deemed "software-defined storage," often pool storage to better utilize capacity and performance. But that doesn't mean managers don't still need to understand the unique set of challenges VMs place on storage. In this e-book, readers will learn how to cope with these challenges by understanding how virtualization changes the way storage should be provisioned and monitored. They will also learn how new technologies in the storage for virtual environment space can help and what types of applications they are most beneficial for, and how once murky technologies such as software-defined storage have grown to be more clearly defined as viable options for storing VMs.Continue Reading
