Online Data Storage

The increase in the volume of information that companies manage daily contributed to the development of services that would facilitate the expansion of the storage capacities of their interconnected terminals to their local networks. From this activity, precisely, the greatest current challenges arise in terms of data storage on the Internet .

The management of this large volume requires different online services that make it possible to expand the storage capacity of a personal computer that is connected to the network. In this way it is possible to create a physical space that does not belong to a specific device; However, it can be used by users who are connected to the cloud to save or access certain information.

Data Storage on the Internet

It is understood, then, by Internet storage the creation of new storage spaces that do not belong to the hard disk of the computers that are connected to a network. Therefore, as a user of the network, through your devices, you can use these new spaces to manage (save, create, modify or delete) your data.

In this way, network data storage is related to the expansion of the storage capacity of a computer or of the devices belonging to a given network, as long as you have access to this storage through the local network.

Organizations and people use different platforms for storing their data. In a simple way, the matter can be understood as the connection of new hard drives in a network. These can be accessed by computers that are connected to that network to manage their information.

Network storage systems

There are mainly three network storage systems, which are: network connected storage (NAS), direct connection storage (DAS) and storage area network (SAN). Below we detail what these systems consist of.

NAS storage systems:

The Network Attached Storage , or network connected storage, is a storage system that incorporates its own connection and treatment scheme for the requests that users make to access the information. Therefore, you do not need servers to work on a local network.

This is one of the reasons why some users and small businesses use them, because it allows the information to be stored in an orderly manner, as well as to back it up by creating backup copies. Added to this is the fact that you will see that the system configuration is simple, so you can implement it in a few minutes even if you have little experience.

The principle of operation of NAS storage systems is as follows: these are connected to the network access point ( router ). The TCP / IP protocol is used to access the data . Once configured, it can be accessed from all points of the network using a browser .

DAS storage system:

In the Direct Attached Storage , or direct connection storage system, it is necessary to have a server to manage access to the data, in which one or more hard drives are connected . Having access to the local network you will see the storage space provided by the system as if it were a device that was connected to your computer.

The configuration of this storage system is usually quite simple for private users. Making an analogy, it can be said that when using a DAS storage system you have the same experience that distinguishes when connecting an external hard drive to a computer or laptop .

SAN storage system:

The Storage Area Network or storage area network has some aspects in common with the DAS system. Precisely, the SAN system is considered an evolution of this.

This storage system has a more complex architecture than we have explained before. Similarly, private users find it more laborious to perform their configuration, management and maintenance. For this reason it is less used by these, but in large companies it has great acceptance.

With this network storage system, multiple hard drives are interconnected to a controller . This is responsible for concatenating its capabilities, which results in the creation of a single storage space . The next step is to connect the system to a server with the purpose of carrying out the correct manipulation and management of the data stored in this common space. For all this to take place, it is necessary to connect the system to the local network.

SAN systems and cloud storage

SAN network storage systems allow unlimited storage of a server. In addition, once implanted they allow access to authorized personnel from anywhere. These advantages are used to support cloud storage services.

Thus, when using the cloud, users have the possibility to store and access information via the Internet , without using their computer’s hard drive; A person connects from any country and manages to access virtually a storage space that is physically distributed in numerous data centers located in different places.
