In computer engineering, a data storage system is defined as a hardware device where data is stored. What concerns businesses today is the exponential growth in data that has occurred—enormous amounts of data must be stored and be quickly accessible. So data storage systems are incredibly important to your business.
In a small business with a single server, the data storage system where the information is stored is typically the server’s built-in hard disk. In larger corporate environments, the system might consist of racks upon racks of dedicated storage systems, which work in tandem to provide high performance and redundancy.
Storage system technology has changed radically in recent years. The SAN and NAS systems have taken over in popularity because of their excellent performance, scalability, compatibility, and fault-tolerant capabilities.
