Network storage is a type of computer storage, which involves accessing the information over a computer network. Network computers do not contain internal secondary storage devices; the information is stored on the server or storage system. Network storage is defined as keeping the data files or applications in a centralized file server or storage system.
Direct Attached Storage (DAS): It refers to a digital storage system that is directly attached to an individual server or the client. There is no storage network involved. More than one server may be present but the storage for each server is managed separately and cannot be shared by another server. DAS is primarily used as a term used to differentiate non-networked storage from SAN and NAS.
Direct Attached Storage refers to the disk drives contained within the computer cabinet and are connected to Central Processing Unit (CPU) via Host Bus Adapter (HBA). DAS devices can also be in external housings that are connected to the server using HBA. Most computers and servers have Direct-Attached Storage (DAS). The common example of DAS is the internal hard drive of a server computer. Storage devices, such as hard disks, CD-ROM drives and tape dives are attached directly to the system in a DAS configuration. The systems, to which they are attached, are usually a network server running an Operating System: MS Windows, Novell NetWare, Linux, or UNIX. The storage devices are connected to these systems using a storage device interface, such as Integrated Drive Electronics (IDE), Fiber Channel or Small Computer Systems Interface (SCSI), which supports only external devices.
DAS technology implementation is inexpensive; therefore, is known to be the most widely used method of storing information on todays networks. However, it has certain drawbacks. The storage devices are accessed through a server; hence, valuable system resources are used. In addition, the licensed connection is required to access the data. DAS restricts the amount of disk storage space that can be used. DAS is unable to share data or unused resources with other servers. The introduction to Network-attached storage provides resolution to some of the above-mentioned issues.
Network Attached Storage (NAS): A specialized server connecting to the network and is dedicated to nothing more than file sharing. NAS is a data storage method that uses special devices, which are directly connected to the network media. An IP address is assigned to these devices, which can be accessed either directly or via a server by the clients.
NAS enables the expansion of available storage to a network by adding another NAS device to the network. Since, NAS devices operate independently of network servers; therefore, in the event of server failure, the data is still accessible by the clients. In NAS configuration, although there are many servers running different operating systems, the storage, security, and management of data can be centralized. An extra level of fault tolerance to the network is bought about by taking some fault tolerant measures, such as RAID. The performance of NAS devices depends on cached memory and network interface to an extent.
