Storage virtualization abstracts the management of storage away from physical hardware and creates a centralized pool of storage capacity. This enables applications to run on a single or greatly smaller number of servers. It also eliminates dependencies between data accessed at the file level and its physical location on the server, making it simpler to optimize storage use and to perform non-disruptive migrations of files and much more.
Storage virtualization is a key component of many modern IT environments. It can help improve IT processes and lower costs. It allows an organization to reduce costs by reducing the number of servers needed for each application. It can also make it easier to move to new technology platforms.
Virtual data storage can streamline the IT environment as it reduces the amount of hardware required to support applications. In the past, each application needed its own hardware that was dedicated to it – like printer servers or email servers. With traditional storage models for data, organizations crowded their datacenters with redundant and expensive hardware. With virtualization of storage, an IT team can take a more simplified approach and reduce the cost of managing a complex datacenter.
Using virtual storage, an organisation can consolidate its server SAN and reduce its CAPEX by using the same internal drives to serve both purposes. It also can achieve higher efficiency and greater utilization of storage by merging multiple storage arrays and disks into one pool that can be accessed by all the servers in the SAN.
