DAS
Direct-attached Storage
• DAS is a storage technology that allows you to
store data to the storage location, which is
directly attached to a server either as internal
hard disk or as a rack-mounted redundant
Array of inexpensive Disk (RAID) connected to
a server with the help of SCSI or Fiber
Channel.
• जब server डाटा को store करने के लऱए इंटरनऱ HDD या
RAID का use करता तो इस टे क्नोऱॉजी को DAS कहा जाता
