mode
mode. The set of attributes that specify the type and access permissions for a file. See also
file mode
.
modular cabinet. A cabinet with an integrated 19-inch rack equipped with a power
distribution unit (PDU), doors, slides, brackets, castors, leveling pads, and optional
side panels. See also cabinet
.
modular I/O. An I/O system that uses I/O adapter modules and provides direct I/O
connectivity for all processors in the core tetrahedron. See also I/O adapter module
(IOAM).
modular ServerNet expansion board (MSEB). A ServerNet expansion board (SEB) that
uses plug-in cards (PICs) to provide a choice of connection media for routing
ServerNet packets.
modular system. A complete server system in which processors, storage, input/output
components, and interconnect components are separate, self-contained, replaceable
modules. A modular system occupies one or more racks and allows independent
evolution and optimization of each kind of module.
module. (1) Part of the group, module, slot naming convention for uniquely identifying the
logical location of a component within a system. A module is a subset of a group, and it
is usually contained in an enclosure. A module contains one or more slots. A module
can consist of components sharing common interconnect, such as a backplane, or it
can be a logical grouping of components performing a particular function. See also
group
. (2) A set of I/O devices or services that share a common protocol and can be
controlled by a single module driver in the extensible I/O (XIO) subsystem.
MON object type. The Subsystem Control Facility (SCF) object type for the storage pool
master process.
mount. To make a fileset accessible to the users of an Expand node.
mount point. In the Open System Services (OSS) file system, a directory that contains a
mounted fileset. The mounted fileset can be in a different file system.
MRouter. A field-programmable gate array (FPGA) or application-specific integrated circuit
(ASIC) that is part of the serial maintenance bus (SMB) architecture for HP NonStop™
S-series enclosures. The MRouter distributes the SMB throughout a group.
MSEB. See modular ServerNet expansion board (MSEB).
MSEB CBB. See MSEB common base board (CBB).
MSEB common base board (CBB). In modular ServerNet expansion boards (MSEBs), the
printed wiring assembly (PWA) that plug-in cards (PICs) are installed on.
