To send an SSL connection, however, or to open a secure connection, your
application must first have an encryption key assigned to it by a Certification
Authority. Once it has a unique key of its own, you can establish a secure
connection with every other application that can "speak" the SSL protocol.
serial ATA (SATA) The evolution of the ATA (IDE) interface that changes the physical architecture
disk from parallel to serial and from primary-secondary (master-slave) to point-to-point.
Unlike parallel ATA interfaces that connect two drives; one configured as primary
(master), the other as secondary (slave), each SATA drive is connected to its own
interface.
simple network A widely used network monitoring and control protocol. Data is passed from
management SNMP agents, which are hardware and/or software processes reporting activity
protocol (SNMP) in each network device (hub, router, bridge, etc.) to the workstation console used
to oversee the network. The agents return information contained in a MIB
(Management Information Base), which is a data structure that defines what is
obtainable from the device and what can be controlled (turned off, on, etc.).
small computer A standard, intelligent parallel interface for attaching peripheral devices to
systems interface computers, based on a device independent protocol.
(SCSI)
smart copy A feature within the automigration process that is under the control of the backup
application and managed via the VLS device's SMI-S interface. This requires the
backup application to support the HP smart copy interface. (Smart copy is similar
to snapshot.)
SMI-S Allows control of the virtual tape library by a connected destination library for
the purpose of implementing automigration. SMI-S support allows applications
attached to the VLS to detect the virtual library configuration and to allow some
users to change the state of the VLS.
storage area A centrally managed network that allows any-to-any interconnection of servers
network (SAN) and storage systems.
storage pool Multiple disk arrays logically grouped together from which the dynamic disk
filesystem allocates storage. The disk arrays in a VLS are automatically configured
into one storage array.
tape drive (1) A device that reads data from and writes data onto tape.
(2) A software emulation of a tape drive is called a virtual tape drive.
virtual tape Also known as a piece of virtual media or a VLS cartridge. A disk drive buffer
that emulates one physical tape to the host system and appears to the host backup
application as a physical tape. The same application used to back up to tape is
used, but the data is stored on disk.
Data can be written to and read from the virtual tape, and the data on that virtual
tape can be migrated to physical tape.
virtual tape drive An emulation of a physical transport in a virtual tape library that looks like a
physical tape transport to the host backup application. The data written to the
virtual tape drive is really being written to disk.
See also virtual tape library.
virtual tape library A disk drive buffer containing virtual tape and virtual tape drives.
See also virtual tape drive.
