MB
MB. See megabyte (MB).
Mbps. See megabits per second (Mbps).
media access control (MAC) address. A value in the Medium Access Control sublayer of
the IEEE/ISO/ANSI LAN architecture that uniquely identifies an individual station that
implements a single point of physical attachment to a LAN.
megabits per second (Mbps). A data rate equal to 1,048,576 bits per second.
megabyte (MB). A unit of measurement equal to 1,048,576 bytes (1024 kilobytes) for
memory size. See also gigabyte (GB), kilobyte (KB), and terabyte (TB).
memory pool. Data structure used by QIO client processes for control structures and
variable size buffers that are not used for data transfers.
message buffers. Data structures used by QIO client processes to send and receive data
on the LAN.
message descriptors. Data structures used to reference message buffers.
MFIOB. See multifunction I/O board (MFIOB).
MON object type. The Subsystem Control Facility (SCF) object type for the storage pool
master process.
multifunction I/O board (MFIOB). A ServerNet adapter that contains ServerNet
addressable controllers (SACs) for SCSI and Ethernet; a service processor; ServerNet
links to the processor, to the two ServerNet adapter slots, and to one of the ServerNet
expansion board (SEB) slots; and connections to the serial maintenance bus (SMB),
which connects components within an enclosure to the service processor.
network. Two or more computer systems (nodes) connected so that they can exchange
information and share resources. See also Expand network, wide area network (WAN),
and local area network (LAN)
.
noninteractive mode. A mode of operation that usually involves a command file (an EDIT
file that contains a series of commands). Contrast with interactive mode.
nonsensitive command. A command that can be issued by any user or program that is
allowed access to a subsystem—that is, a command on which the subsystem imposes
no further security restrictions. For Subsystem Control Facility (SCF) subsystems,
nonsensitive commands are those that cannot change the state or configuration of
objects; most of them are information commands. Contrast with sensitive command.
NonStop NS-series. Refers to fault-tolerant HP computers that support the NonStop OS
and are based on the Intel® Itanium® processor. Integrity NonStop NS-series systems
run the Itanium instruction set and can run TNS object files by interpretation or after
