multifunction I/O board (MFIOB)
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.
multilane link. A communication link between HP NonStop™ Cluster Switches that can
consist of multiple ServerNet cables. Two-lane links and four-lane links are examples
of multilane links.
multimode fiber-optic (MMF) plug-in card (PIC). A plug-in card (PIC) for the modular
ServerNet expansion board (MSEB) and I/O multifunction (IOMF) 2 customer-
replaceable unit (CRU) that supports the multimode fiber-optic (MMF) interface.
multimode fiber-optic (MMF) ServerNet cable. A fiber-optic cable that either allows more
than one mode to propagate or supports propagation of more than one mode of a
given wavelength. MMF ServerNet cable typically supports shorter transmission
distances than single-mode fiber-optic (SMF) ServerNet cable
.
multiplexed. The action of separating data traffic from one line onto several distinct lines or
of combining data traffic from several distinct lines onto one line.
mutex. See mutual exclusion (mutex).
mutual exclusion (mutex). An operating mode with interrupts disabled.
NAM. See Network Access Method (NAM).
named resource list (NRL). A table that contains one entry for each device and named
process in the system. A logical device number (ldev)
is an NRL index.
national-standards-body conforming POSIX.1 application. An application that both:
•
Uses only the facilities described in ISO/IEC IS 9945-1:1990 and approved
standards of a specific member of the ISO or IEC (the national standards body)
•
Documents use of only those facilities and approved standards and documents all
options and dependencies on limits
native. An adjective that can modify object code, object file, process, procedure, and mode
of process execution. Native object files contain native object code, which directly uses
the MIPS processor's instruction set and the corresponding conventions for register
handling and procedure calls. Native processes are those created by executing native
object files. Native procedures are units of native object code. Native mode execution
is the state of the process when it is executing native procedures.
native link editor. See nld utility.
native mode. See TNS/R native mode.
