The management of virtual storage is an essential aspect of managing any IT infrastructure. In contrast to physical hardware, where it is easy to switch out devices and upgrade them to more efficient ones, this kind of storage is a bit more complicated and requires the right management tools to get the most value out of it.
Virtualization is the most efficient way to reduce complexity. It allows you to pool together resources and create an effective storage solution that can handle a larger volume of data. Virtualization can be used on a variety of platforms and devices, including network appliances that offer centralized storage to your applications, and virtualized storage software that uses the hardware underpinning it to provide an entire storage pool to your system.
For instance the network appliance can use a physical Fibre Channel (FC) or iSCSI SAN to present a storage pool that appears to be one physical disk to the host or server. It receives input and output (I/O) requests and transmits the requests to different physical location on the pool of storage, without the host or server knowing what is going on behind the background. The mapping granularity dictates how quickly meta-data can be updated and how much space will be needed during a migration and how quickly the previous physical location can be marked free.
Virtualized storage solutions also offer high availability by mirroring data between multiple servers. This means you won’t lose critical business data if one of your server nodes fails. The data will be automatically routed to other servers that are healthy within the cluster.
