NonStop System Glossary

distribution subvolume (DSV)
A subvolume containing program files for a particular software product along with the RVU document
(softdoc) file for that product. The format for a DSV name is Ynnnnrrr or Rnnnnrrr, where nnnn
is the software product number and rrr is the base version identifier (such as D20) or software
product revision (SPR) identifier (such as AAB).
DLC
See data link control (DLC).
DLL
See dynamic-link library (DLL).
DMA
See direct memory access (DMA).
DMR
See duplex.
DNS
See Domain Name System (DNS).
DNS server
A server that resolves hostnames to Internet protocol (IP) address mapping queries. These queries
originate from either client computers, which are known as resolvers, or other Domain Name
System (DNS) servers, which accounts for the distributed nature of DNS. See also Network
Information Service (NIS).
docs.hp.com
The application for accessing, searching, and viewing technical publications and support information
for NonStop systems. Effective with the H06.11 and the G06.24 RVUs, docs.hp.com replaced
theHP NonStop Technical Library (NTL).
domain
1. On the Internet, a part of the naming hierarchy. Syntactically, a domain name consists of a
sequence of names (labels) separated by periods (dots).
2. On a NonStop server, a pair of service processors, the associated router clouds, and the
attached replaceable units.
3. A set of objects over which control or ownership is maintained. Types of domains include power
domains and service processor (SP) domains.
Domain Name System (DNS)
A series of names that are located and translated into Internet protocol (IP) addresses. A domain
name is a meaningful and easy-to-remember handle for an Internet address. Because maintaining
a central list of domain name/IP address correspondences would be impractical, the lists of domain
names and IP addresses are distributed throughout the Internet in a hierarchy of authority. See also
DNS server, Network Information Service (NIS), and ping.
