Snap Server Administrator Guide
LED (Light-Emitting Diode)
An electronic device that lights up when electricity is passed
through it.
Linux
A UNIX-like operating system that was designed to provide
personal computer users a free or very low-cost operating
system comparable to traditional and usually more
expensive UNIX systems. The GuardianOS is based on the
Linux operating system.
load balancing
A process available only in dual-Ethernet configurations.
The Ethernet port transmission load is distributed among
two network ports (assuming the cards are configured for
load balancing). An intelligent software adaptive agent
repeatedly analyzes the traffic flow from the server and
distributes the packets based on destination addresses.
local group/local user
A group/user defined locally on a Snap Server using the
Administration Tool. The local user is defined by the server
administrator. Windows domain, ADS, and NIS users are not
considered local.
MAC (Media Access Control)
In the Open Systems Interconnection (OSI) model, one of
two sublayers of the Data Link Control layer. Concerned with
sharing the physical connection to the network among
several computers. Each Ethernet port has a unique MAC
address. Snap Servers with dual-Ethernet ports can
respond to a request with either port and have two unique
MAC addresses.
maintenance mode
A series of HTML screens that allow you to perform repair,
upgrade, or reinstall the GuardianOS in a disaster recovery
situation.
MIB (Management Information
Base)
A formal description of a set of network objects that can be
managed using the Simple Network Management Protocol
(SNMP). The format of the MIB is defined as part of SNMP.
mirroring
Used in RAID 1, a process of storing data on one disk and
copying it to one or more disks, creating a redundant
storage solution. RAID 1 is the most secure method of
storing mission-critical data.
mounted
A file system that is available.
multihomed
A Snap Server that is connected to two or more networks or
has two or more network addresses.
