Virtual storage management is a critical part of any IT infrastructure. In contrast to physical hardware, where it is easy to change out devices or replace them with better ones, this type of storage is more complex and requires the right management tools to make the most of it.
Virtualization is the best way to handle the complexity. It lets you combine resources to create an effective storage solution that can handle a greater volume of data. Virtualization is available on many platforms, such as network appliances, that offer central storage for your applications, or virtualized storage software that utilizes the hardware in order to deliver a pool of storage.
A network appliance, such as it can make use of physical Fibre Channel SAN (FC) or iSCSI SAN in order to present an array of storage that appears as an individual logical disk servers or hosts. It takes in input/output (I/O) requests and then forwards them to a different physical location within the pool of storage, without the server or host being aware of what’s taking place behind the behind the scenes. The mapping granularity affects how quickly meta-data is updated and how much storage space is required during the migration process, and how quickly a previous physical location can become available.
Virtualized storage solutions can offer high availability by mirroring data across multiple servers. This will ensure that you don’t lose important business data if one of your server nodes fails. The data will be automatically redirected to other healthy servers within the cluster.
