SAN or DAS … which one is better for your company?

Storage Area Network (SAN) is a dedicated high speed network of storage devices which are connected to the servers. The server can access the shared storage if that storage is directly connected to the server. The hardware components in SAN are cables, Host Bus Adapters (HBAs) and switches. All the switches and storage devices connect using cables. SAN is helpful in backup management and data can be trusted transferred from one device to another by not involving the server. This helps to increase the system speed and eliminates the server need for every transfer. Direct Attached Storage is a digital storage which is directly attached to the server without a storage network in the middle.  DAS devices have multiple ports and can be shared among multiple computers. SCSI is the preferred protocol used in SAN.
