Owner manual

A device that stores data on a disk and provides random access to addressable locations
on the disk. There are two types of disk drives:
On magnetic drives, access is provided by magnetic read/write heads.●
On optical drives, access is provided by a low-intensity laser beam.●
disk volume
A logical disk drive. A volume can be one or two physical drives. In NonStop S-series
servers, volumes have names that begin with a dollar sign ($), such as $DATA.
domain
A set of objects on the server over which control or ownership is maintained. Types of
domains include power domains and serial maintenance bus (SMB) domains.
download
To transfer software from one location to another, where the transferring entity initiates
the transfer.
dump

dynamic information
Information that represents the set of supported resources that actually exist in the current
configuration of the server. Dynamic information is gathered from a server through the
process of discovery.

E
enclosure
In NonStop S-series servers, a structure or assembly that houses system components or
peripheral devices. Enclosures that rest on the floor are called base enclosures.
Enclosures that rest on another enclosure are called stackable enclosures.

Ethernet
A local area network (LAN) that uses the carrier sense multiple access with collision
detection (CSMA/CD) access method on a bus topology and is the basis for the IEEE
802.3 standard.
