With the advent of computers and the recent
advent of information and communication technologies (ICT), humans have taken
on the challenge of inventing or improving devices and mechanisms that will
allow them to securely store data. data.
The increase in the volume of information
processed by companies on a daily basis has contributed to the development of
services that will increase the storage capacity of their terminals connected
to their local networks. It is because of these activities that the biggest
current problems in terms of data storage on the Internet arise.
To manage this large volume, various online
services are required to increase the storage capacity of a personal computer
connected to the network. In this way, you can create a physical space that
does not belong to a specific device; however, users connected to the cloud can
use it to store or access certain information.
Nowadays, very often when we use the term
network storage or data storage on the Internet, we all understand that we are
talking about cloud services. However, it should be noted that the concept of
online storage includes other alternatives in addition to cloud storage.
What is an Internet Data Warehouse?
Thus, online storage is understood as the
creation of new storage spaces that do not belong to the hard drives of
computers connected to the network. Thus, as a web user through your devices,
you will be able to use these new spaces to manage (save, create, modify or
delete) your data.
Thus, network attached storage is associated
with expanding the storage capacity of a computer or devices belonging to a
specific network, provided that this storage is accessed via a local network.
Organizations and individuals use different
platforms to store their data. In simple terms, this can be unstated as
connecting new hard drives to the network. They can be accessed by computers
connected to the specified network to manage their information.
In addition to the storage of your device, as
a user, you have access to additional storage that is used by all devices
connected to the local network.
NAS storage systems
Network attached storage or network attached
storage is a storage system that includes a self-connection scheme and the
processing of requests made by users to access information. Hence, you don't
need servers to run on your local network.
This is one of the reasons why some users and
small businesses use them, as it allows you to keep information in an orderly
way, as well as create backups by creating backups. Added to this is the fact
that you will find that the system configuration is simple, so you can
implement it in a few minutes, even if you have little experience.
NAS storage systems work as follows: they
connect to a network access point (router). The TCP / IP protocol is used to
access the data. Once configured, it can be accessed from all points on the
network using a browser.
On the network, they have a unique identifier
and address, so they do not depend on it. They have their own operating system
(usually a Linux version). Its capabilities and functions depend on its price. In
addition, its features can be added or disabled.
Among the actions they allow you to perform
are automatic backups and downloads from P2P networks or via Torrent. They can
also be used as a media server, FTP server, print server, and even as a web
server.
SAN storage system
SAN or SAN has some aspects in common with
DAS. In fact, the SAN system is considered an evolution of this.
This storage system has a more complex
architecture than the ones we explained earlier. Likewise, it is more difficult
for private users to customize, manage and maintain them. For this reason, they
use it less often, but in large companies it is in great demand.
In this networked storage system, multiple
hard drives are connected to the controller. This is responsible for combining
their containers, resulting in a single storage space. The next step is to
connect the system to the server to perform the correct manipulation and
control of the data that is stored in this shared space. In order for all this
to happen, it is necessary to connect the system to the local network.
The SAN system, despite its high initial cost
of implementation, is widely used by large companies because, once installed,
it provides more flexibility and scalability. This way, you can modify and
expand the storage space as needed. In addition, with this system, the storage
capacity is better optimized as space that is not used by one person can be
used by another.
At the same time, it springs you the ability
to create data centers in different geographic locations that end up paying
homage to the same business unit so that the risk of information loss due to a
disaster is minimized.
The SAN system allows people to access the
same information regardless of their geographic location. Thus, employees of a
company with branches in different countries can work in parallel and access
the same data, regardless of where their data centers are located.
