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.
Direct attached storage vs nas.
Direct attached storage is a fairly basic low maintenance low cost solution where the storage system is a part of the actual host computer or connected directly to the host computer.
A nas is a single storage device that operates on data files while a san is a local network of several devices.
Das is that nas is accessible to multiple servers.
Direct attached storage can be deployed in a number of forms.
Storage area networks and network attached storage provide networked storage solutions.
Das storage can be shared with others but only at the os level.
Das vs nas direct attached storage.
