Nas And San Network Diagram

Storage area network san.

Nas and san network diagram. A storage area network san or storage network is a computer network which provides access to consolidated block level data storage sans are primarily used to access storage devices such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct attached storage a san typically is a dedicated network of storage devices not accessible through. When san and nas are joined together into one device in this way it s sometimes referred to as unified san. To add nas to a san a nas gateway can be used to support both systems. San can be considered as a technology that combines the best features of both das and nas.

A storage area network san is a dedicated high speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers. All networks designed with conceptdraw diagram are vector graphic documents and are available for reviewing modifying and converting to a variety of formats image html pdf file ms powerpoint presentation adobe flash or ms visio. San uses block storage. The name storage area network itself implies that the storage resides in its own dedicated network.

The san and nas are the information storage techniques which are often mixed with one another because of alike acronyms. These two industry factors have led to a partial convergence of nas and san approaches to network storage effectively creating high speed high capacity and centrally located network devices. This gives the ip network access to the san s block level storage while processing client requests through nfs and smb sharing protocols. A san typically uses fibre channel connectivity while nas typically ties into to the network through a standard.

San and network attached storage nas are both network based storage solutions. Hosts can attach the storage device to itself using either fiber channel tcp ip network san uses iscsi when used over tcp ip network. But many mainstream san arrays now. This page compares das direct access storage vs nas network attached storage vs san storage area network and mentions difference between das direct access storage nas network attached storage and san storage area network the architectures advantages and disadvantages of das nas and san are also covered.
