Managing Virtual Storage

Virtual storage management is a crucial part of any IT infrastructure. As opposed to physical hardware, which you can easily swap out devices or replace them with more powerful ones, this kind of storage is complex and requires the right tools for management to make the most of it.

Virtualization is the most efficient way to handle the complexity. It allows you to pool resources and create a storage solution that can handle more data. Virtualization is available on a variety of platforms which include network devices that provide centralized storage to your applications, as well as virtualized storage software that utilizes the underlying hardware to deliver the same storage pool to your system.

For example an appliance on the network can utilize physical Fibre Channel (FC) or iSCSI SAN to present a pool of storage that appears to be one physical disk to the server or host. It intercepts requests for input or output (I/O) and sends them to a different location within the storage pool, without the host or server knowing what’s happening behind the scenes. The mapping granularity dictates how quickly the meta-data will be updated and how much space will be required for a migration and how quickly the physical location can be marked as free.

Virtualized storage solutions can also offer high availability by mirroring the data across multiple servers. This ensures you won’t lose crucial business data in the event that one of your server nodes fails. The data will be automatically redirected to other healthy servers within the cluster.
