DAS (Direct Attached Storage)
Storage
Storage that is directly connected to a server.
An acronym for Direct Attached Storage, those parts of a Wide Area Network in which the mass storage devices are connected locally
DAS is storage that is directly connected to a server by connectivity media such as parallel SCSI cables. This direct connection provides fast access to the data; however, storage is only accessible from that server. DAS include the internally attached local disk drives or externally attached RAID (redundant array of independent disks) or JBOD (just a bunch of disks). Although Fibre Channel can be used for direct attached, it is more commonly used in storage area networks.
