[. . . ] · Device Name Displays the name of the target (device). · Serial Number Displays the SCSI serial number automatically assigned to the target by the GUI. Cartridge Map · Element Indicates whether the slot is used as a bin for a virtual tape-cartridge or contains a virtual drive. · Media Type Identifies which type of media is emulated, for example, LTO-2 tape devices. · Bar Code Label Lists the label assigned to the element based on the labeling scheme used by the VL or reports Empty if there is no label assigned. · Used Capacity Displays how much space (in gigabytes) is currently consumed by the virtual tape. View/Edit Virtual Standalone Tape Use this page to view a list of the existing standalone devices, to access the page where you can change the attributes of a device (click Modify), or to remove a device (click Delete). · · · · Device ID Indicates the ID automatically assigned to the device by the system or by the user. Device Name Indicates the name automatically assigned to the device by the system. Device Status Indicates the current state of the device. Size (GB) Indicates the amount of space currently being used by the device. 68 VLS1000i GUI NOTE: The size of a device reflects the space that is currently being used on a device; one GB equals one billion bytes. (The appliance uses the calculation of 1000 x 1000 x 1000 instead of 1024 x 1024 x 1024. ) · Compression Indicates whether the compression feature was enabled for the device. Modify Virtual Standalone Tape Configuration Use this page to modify the compression, maximum size, device name, and host name for an existing virtual Tape Device. · Device Type Indicates that the device is a Standalone Tape Drive. · Enable Tape Compression If your backup software supports a hardware compression feature for use with tape, you can use this option to emulate that feature. For optimal backup performance, leave this check box cleared; to maximize the backup storage capacity, select this check box. · Maximum Cartridge Size Enter the maximum size that to allow the device to reach. Set the maximum size to the physical capacity in order to grow to full capacity. NOTE: If you decide to change the maximum size at a later date, be aware that you can only increase the size; you cannot reduce it. To use a device with a smaller maximum size, you must either delete this device and recreate it using the desired size, or create an additional device that uses the desired size. · iSCSI Device Name To change the default target name of a device, type the new name in this field. (All targets must have an iSCSI name. ) · Current Cartridge Size Indicates the amount of space currently being used by the device. · Tape Serial Number The serial number assigned by the GUI to this device. [. . . ] For example, if you have two power supplies with one that takes over if the other one dies, that's redundancy. The evolution of the ATA (IDE) interface that changes the physical architecture from parallel to serial and from master-slave to point-to-point. Unlike parallel ATA interfaces that connect two drives; one configured as master, the other as slave, each serial ATA drive is connected to its own interface. A widely used network monitoring and control protocol. [. . . ]
