Managing virtual storage is an important component of managing any IT infrastructure. This kind of storage unlike physical hardware, that allows you to replace devices with superior ones or swap them out, is a bit more complicated and requires management tools to get the most of it.
Virtualization is the best approach to handle the complexity. It lets you pool resources and create an efficient 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 makes use of the underlying hardware to deliver an entire storage pool to your system.
A network appliance, like is able to use physical Fibre Channel SAN (FC) or iSCSI SAN in order to present a storage pool that appears as an individual logical disk servers or hosts. It intercepts input/output (I/O) requests and sends the requests to a different physical location on the storage pool without the host or server being aware of what’s taking place behind the background. The mapping granularity determines how fast the meta-data can be updated and how much space will be needed during a migration and how quickly the physical location can be marked free.
Virtualized storage solutions also offer high availability through mirroring data between multiple servers. This ensures you won’t lose vital business information should one of your server nodes fails. The data will automatically be redirected to other servers that are healthy within the cluster.
