SnapServer 7.0 Administrator's Guide
Kerberos
A secure method for authenticating a request for a service used by ADS. Kerberos lets a
user request an encrypted "ticket" from an authentication process that can then be used to
request a service from a server. The user credentials are always encrypted before they are
transmitted over the network.
In Windows 2000/XP, the domain controller is the Kerberos server. The Kerberos key
distribution center (KDC) and the origin of group policies are applied to the domain.
LACP
Link Aggregation Control Protocol provides a method to control the bundling of several
physical ports together to form a single logical channel. LACP allows a network device to
negotiate an automatic bundling of links by sending LACP packets to the peer (directly
connected device that also implements LACP).
LAN
Short for Local Area Network. A network connecting computers in a relatively small area
such as a building.
LCD
Short for Liquid Crystal Display. An electronic device that uses liquid crystal to display
messages.
LED
Short for Light-Emitting Diode. An LED is a type of diode that emits light when current
passes through it. Visible LEDs are used as indicator lights on electronic devices.
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. GuardianOS is based on the Linux operating system.
Load Balancing
A process available only in multi-Ethernet configurations. The Ethernet port transmission
load is distributed among two or more 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 SnapServer using the Web Management Interface. The
local user is defined by the server administrator. Windows domain, ADS, and NIS users are
not considered local.
Logical Drive
A drive that is defined or created from regions of an array, a whole array, or a combination
of regions of different arrays. The logical drive appears as a single disk to one or more host
systems.
Logical Drive Availability
To accommodate hosts with multiple ports and multiple host systems, it is possible to
restrict a logical drive's availability to a particular HBA or controller port. Access can be
enabled or disabled for each host port of each controller.
