Before implementing a new DSS at your company, you need to understand their varieties and principles of operation. A personal computer hard drive or hard drive is the first storage system, and despite the constant increase in its volume, this equipment in many cases no longer copes with its tasks. Modern centralized disk storage (DAS) can consist of 16 drives made outside the personal computer, can handle a large flow of information, but the speed of its transmission to other network users may not be high enough.
This problem was to be solved by a network data warehouse (NAS), the architecture of which allows you to work centrally with information using a highly specialized device integrated into the local network. However, over time, cloud storage began to require more volume, clear distribution of devices, increasing processing speed. To do this, SANs were made into a separate network, which looks like a large hard drive.
