- The price per megabyte is low, therefore the costs of adding additional drives and/or server are very reasonable - Manage storage using the Network Operating System of the attached server. - Scaleable to 16 devices for each SCSI host adapter in the server. - Limited dependency on Network Bandwidth. - Separation of Storage and Server Purchases. - Operating system independent.
Works independently without host support Centralizes storage control Provides fast, easy installation and administration Offers a potentially lower cost alternative Provides cross-platform file server Operates unattended with low data security risk Fast time to data – fast recovery, minimal downtime
