Virtual Storage


Virtual storage is defined as a pool of different storage resources connected together to facilitate the ever-growing storage demands of the users. Virtual storage forms the basis of the cloud infrastructure because it is also referred to as cloud storage many times and is intensely used for data backup purposes. As the name implies, virtual storage forms a layer of abstraction between the user and the actual storage unit. In this article, we will talk about a common misconception about the virtual storage. We will also learn how virtual storage works and the benefits of using virtual storage. Finally, we will talk a little about StarWind HyperConverged Appliance (HCA).

The misconception about Virtual Storage:

Most of the people in the past used to confuse virtual storage with virtual memory and both these terms were used interchangeably. However, with the advent of cloud computing, the concept of virtual storage became clearer. For making a distinction between the two terminologies, we will state the definitions of both. Virtual memory is, in fact, an extension of RAM, which is borrowed from the hard disk whenever RAM runs out of space whereas virtual storage is the combination of multiple actual storage devices.

Working of Virtual Storage:

Virtual storage works by combining multiple storage resources together such that they act like one single unit. This pool of storage resources can then serve the needs of multiple users. This type of storage is known as virtual because it is in fact designed to be used in a virtual environment. Virtual storage is mostly associated with virtual machines, which are thought of as independent computer systems with their own operating systems and other hardware resources. We can use virtual storage mainly for backup purposes.

Benefits of Virtual Storage:

The benefits of virtual storage are as follows:

➢      Central Management: A virtual storage pool is managed centrally hence; it simplifies the job of a network administrator.

➢      Efficient Hardware Utilization: Because multiple storage devices connect together in order to serve the needs of more than one users.

➢      Reduced Complexity: Because the storage pool is centrally managed.

➢      Cost Efficiency: A large amount of storage space is obtained just by coupling a few storage resources. Hence, a huge storage requirement can be met through virtual storage.

➢      Easier Data Backup Process: Since a huge storage pool is available to the users, hence they can easily backup their important data and restore it whenever they want. Moreover, if your local copy of the data is corrupted or lost, then you can conveniently retrieve it from virtual storage.


StarWind HyperConverged Appliance (HCA):

StarWind HyperConverged Appliance (HCA) is a hardware device that has combined the networking, computation and storage components all together in one single unit. It is designed to help those organizations who are looking to minimize their application downtime but are limited on their IT team resources or budget.

Along with so many other exceptional features, StarWind HyperConverged Appliance (HCA) also supports virtual tape libraries (VTL). StarWind Virtual Tape Library (VTL) is an excellent virtual storage resource that helps the users to store and retrieve their data efficiently. Moreover, StarWind HyperConverged Appliance (HCA) also provides support for StarWind Virtual Storage Area Network (VSAN), which means that you can get multiple benefits just by using a single StarWind HyperConverged Appliance (HCA).


In this article, we talked about the need for virtual storage in today's IT industry. We drew a comparison between virtual storage and virtual memory by stating their definitions thus removing the misconception about virtual storage. We explained the working of virtual storage and also the numerous benefits that you get by using the virtual storage. Finally, we discussed the working and features of StarWind HyperConverged Appliance (HCA) and tried to relate it to the modern virtual storage technology.
