failover A strategy that enables one Ethernet port to assume the role
of another port if the first port fails. If a port fails on a Snap
Server, the second port assumes its network identity (if the
two Ethernet cards have been configured for failover). When
the port comes back online, the original identities are
restored. Failover is possible only in a dual-Ethernet
configuration.
FTP (File Transfer Protocol) A standard Internet protocol that provides a way to
exchange files between computers on the Internet.
By
default, a Snap Server is set up to be an FTP server.
full-duplex A type of transmission that allows communicating systems
to both transmit and receive data simultaneously.
gateway The hardware or software that bridges the gap between two
network subnets. It allows data to be transferred among
computers that are on different subnets.
GID (group IDs) On a Snap Server, the unique ID assigned to each group for
security purposes.
GuardianOSImage.gsu An image file used to upgrade the GuardianOS.
half-duplex A type of transmission that transfers data in one way at a
time.
hidden share A share that restricts the display of the share via the
Windows (SMB), Web View (HTTP/HTTPS), FTP, and AFP
protocols.
host name The unique name by which a computer is known on a
network. It is used to identify the computer in electronic
information interchange.
hot spare (local or global) A disk drive that can automatically replace a damaged drive
in a RAID 1 or 5. If one disk drive in a RAID fails or is not
operating properly, the RAID automatically uses the hot
spare to rebuild itself without administrator intervention. A
local hot spare is associated with and available only to a
single RAID. A global hot spare is associated with a single
RAID, but may be used for any RAID in the system.
hot swapping The ability to remove and add disk drives to a system
without the need to power down or interrupt client access to
file systems.
HTTP (Hypertext Transfer Protocol) An application protocol for transferring files (text, graphic
images, sound, video, and other multimedia files) over TCP/
IP on the World Wide Web.
