Storage Industry Overview

However, as internet gets booming later on, the amount of data expands in several

times, digital information content (multimedia, audio and video, animation, etc.)

increases continuously, DAS storage can no longer handle the in-time expansion

issue in network era. Therefore, NAS (Network-Attached Storage) is thus a storage

product under network economy. However, there is still some limitations on NAS, for

example, its File-Based transmission method turns the original jammed information

highway in the internet worse; for continuous big file backup and simultaneous

accesses by multiple persons, the limited 10/100Mbps transmission efficiency of IP

is a big bottleneck, and the goal of concentrated management can not be reached.

SAN (Storage Area Network) architecture was thus born in later 1990s, it mainly

uses optical fiber channel for high speed (Gbps) data transmission, it can also be

used for multiple persons to multiple persons communication, the whole storage

resource can be effectively managed and integrated.
