managing virtual storage is an important aspect of managing any IT infrastructure. Unlike physical hardware, where it is easy to swap out devices or replace them with better ones, this type of storage is more complicated and requires the right management tools to get the most value out of it.
The most effective way to deal with this complexity is by using virtualization technology which lets you pool resources together and create a scalable storage solution that can handle more data. Virtualization is available on a variety of platforms, including network appliances that provide an application-specific storage system that is centralized for you, or virtualized storage software which utilizes the hardware to create the storage capacity of a pool.
For example the network appliance can make use of a physical Fibre Channel (FC) or iSCSI SAN to present a pool of storage that appears to be a single logical disk to the host or server. It takes in input and output requests (I/O), and then transfers them to another location within the storage pool, without the server or host knowing what’s going on behind the scenes. The mapping granularity determines the speed at which meta-data is updated and how much storage space is required during a migration, and how fast a previous physical location can become free.
Virtualized storage solutions are also able to provide high availability by mirroring data across multiple servers. This ensures you won’t lose important business data when one of your server nodes fails. The data will be automatically redirected to other servers that are healthy within the cluster.
