Introduction to DAS

Direct attached storage (DAS) is a data storage technology that connects a storage device to a computer through a SCSI interface, Fibre Channel, or SAS interface. DAS can be used to access and manage data and files.
Compared with common external storage systems, a DAS system can be easily planned and implemented with lower investments. However, a DAS system has no independent operating system and cannot provide cross-platform file sharing. Different DAS systems are not connected. Data is managed in a distributed manner and cannot be shared.
