Controlling virtual storage is a vital aspect of managing any IT infrastructure. This type of storage, unlike physical hardware which allows you to easily replace devices with superior ones or switch them out, is a bit more complicated and requires management tools to get the most of it.
The most effective way to deal with this complexity is to use virtualization technology that allows you to pool resources together to create a storage solution that is scalable that can handle more data. Virtualization is available on a variety of platforms, like network appliances, which present centralized storage for your applications or virtualized storage software which makes use of the hardware to create the storage capacity of a pool.
For instance an appliance on the network can make use of physical Fibre Channel (FC) or iSCSI SAN to present a pool of storage that appears to be a single, logical disk to the server or host. It takes in input and output requests (I/O), and then transmits them to a new location on the storage pool, with neither the host or server knowing what’s happening behind the scene. The mapping granularity determines how fast meta-data is updated and how much storage space is required during the process of migration, and also how quickly a previous physical location can be free.
Virtualized storage solutions also provide high availability through mirroring data between multiple servers. This means that if one of the server nodes fails, you don’t lose access to critical business data as the data is automatically routed to servers that are healthy in the cluster.
