IBM TotalStorage DS6000 Introduction And Planning Manual page 101

administrators to configure, manage, and
monitor the performance of SAN storage
devices from a single console.
multiple relationship FlashCopy
An option of the DS6000 that creates
backup copies from one source to multiple
targets by simultaneously establishing
multiple FlashCopy relationships.
multiple virtual storage (MVS)
Implies MVS/390, MVS/XA, MVS/ESA,
and the MVS element of the zSeries
operating system.
multiplex
The action of transmitting simultaneously.
multiport serial adapter (MSA)
An adapter on the IBM TotalStorage
Management Console that has multiple
ports to which aDS6000 can be attached.
multiprocessor
A computer that includes two or more
processors that have common access to a
main storage. For the DS6000, the
multiprocessors operate in parallel.
MVS See multiple virtual storage.
N
name server
A server that stores names of the
participating DS6000 clusters.
Netfinity
IBM Intel-processor-based server;
predecessor to the IBM xSeries server.
Netscape Navigator
Web browser software manufactured by
Netscape.
network manager
A program or group of programs that is
used to monitor, manage, and diagnose
the problems of a network. (GC)
node The unit that is connected in a
fibre-channel network. A DS6000 is a
node in a fibre-channel network.
non-RAID
A disk drive set up independently of other
disk drives and not set up as part of a
disk pack to store data using the
redundant array of disks (RAID)
data-striping methodology.
nonremovable medium
A recording medium that cannot be added
to or removed from a storage device.
nonvolatile storage (NVS)
Memory that stores active write data to
avoid data loss in the event of a power
loss.
NVS See nonvolatile storage.
O
octet In Internet Protocol addressing, one of the
four parts of a 32-bit integer presented in
dotted decimal notation. See also dotted
decimal notation.
OEMI See original equipment manufacturer's
information.
open system
A system whose characteristics comply
with standards made available throughout
the industry and that therefore can be
connected to other systems complying
with the same standards. Applied to the
DS6000, such systems are those hosts
that connect to the DS6000 through SCSI
or FCP protocols. See also small
computer system interface and
fibre-channel protocol.
organizationally unique identifier (OUI)
An IEEE-standards number that identifies
an organization with a 24-bit globally
unique assigned number referenced by
various standards. OUI is used in the
family of 802 LAN standards, such as
Ethernet and Token Ring.
original equipment manufacturer's information
(OEMI)
A reference to an IBM guideline for a
computer peripheral interface. The
interface uses ESA/390 logical protocols
over an I/O interface that configures
attached units in a multidrop bus topology.
OS/390
The IBM operating system that includes
and integrates functions that many IBM
software products (including the MVS
operating system) previously provided for
the IBM S/390 family of enterprise
servers.
OUI See organizationally unique identifier.
