Information flow is important in todays society whether it is for personal or professional use. Having a centralized location that contains all the information needed to access is the most effective way to achieve a stable information flow. The network storage server is the port between storage devices and users who will read use and affect the data stored there. It can be argued that the network storage server is the most important link in the system. But what is the server and how does it work? While in the concept the three most common storage configurations are somewhat different from each other.
In a directly connected storage or DAS network the network storage server is connected directly to the network. In fact the server is an integral part of the network as a whole. The server acts as a central bridge that connects all users with each other so that they can talk to each other and share information. Without the server the network would not exist. In a DAS the server also contains all storage devices. These devices include CDs internal hard disks and external hard disks as well as any other media devices installed on your computer. This configuration has the most direct access to information enabling shorter access times and faster turnaround times. The disadvantage of this system is that too many users tend to clog the system which ironically can slow down the things.
Another common storage configuration is network-connected storage or NAS system. In this type of storage network storage devices are part of the network but are still independent. In simpler terms there is a computer dedicated for storage but does not contain the main server software. In the same way as DAS all hard disks and CDs are in a single network storage server. The server in this configuration is a very minimal server that allows access to its own devices but does not affect connections with other computers on the network. The advantage of using a NAS is that it does not need to have common operating systems on all clients because it is independent of the network making it easier to check security and handling is easy. One drawback for NAS is that it can still grind the network with too many simultaneous users.
One of the most common types of storage networks used today is the storage network or SAN. SAN puts all storage devices in its own network. The network storage server connects all storage computers to computers outside the network. By using a SAN users from around the world can access data from the same centralized point without having to be physically connected to the network. The server is what tells outside connections how to read the different devices that are connected to it. The Internet is one of the largest SAN systems used today. Using a SAN storage system reduces the amount of bandwidth usage on the network because all data transfer is done on a line that is not dependent on the network. One serious disadvantage of implementing a SAN is that since the storage network can be accessed all the time by users worldwide technicians must be in service sometimes 24 hours a day.
Because the data content can be so versatile the network storage server is the workhorse of all storage networks. The facilitation of communication between users and storage devices a network storage system could not work without the network storage server but the server can still work in many ways if some of the network goes down in some cases. Keeping large amounts of data in a central location while allowing access in different ways has become one of the greatest business of the day enabling the most effective flow of information. In business the effectiveness is the lifeblood for all businesses.
