master service processor (MSP)
master service processor (MSP). A service processor (SP) that provides the basic service
processor functions as well as centralized system functions such as a console port, a
modem port for remote support functions, and system-load control. The enclosure
containing processors 0 and 1 (group 01) also contains a pair of MSPs. See also
expansion service processor (ESP)
.
MB. See megabyte (MB).
Measure. A tool used for monitoring the performance of the HP NonStop™ servers.
Measure can be used to check the performance of a ServerNet cluster.
media access control (MAC) address. A value in the Medium Access Control sublayer of
the IEEE/ISO/ANSI local area network (LAN) architecture that uniquely identifies an
individual station implementing a single point of physical attachment to a LAN.
Media Interface Connector (MIC). A type of head on a fiber-optic cable that has locking
wings on the sides.
megabyte (MB). A unit of measurement equal to 1,048,576 bytes (1024 kilobytes). See also
gigabyte (GB)
, kilobyte (KB), and terabyte (TB).
member. In a structured programming language, an addressable entry within a data
structure. A member can be a simple field or a data structure.
memory-exact point. A location in an accelerated program at which the values in memory
(but not necessarily in the register stack) are the same as they would be if the program
were running on a TNS processor. Most source statement boundaries are
memory-exact points. Complex statements might contain several such points: at each
function call, privileged instruction, and embedded assignment. Contrast with
register-exact point
.
memory manager. A HP NonStop™ Kernel operating system process that implements the
paging scheme for virtual memory. This process services requests generated by
different interrupt handlers as well as by other system processes.
memory page. A unit of virtual storage. In TNS systems, a memory page contains 2048
bytes. In TNS/R systems, the page size is determined by the memory manager and
can vary, depending on the processor type.
memory slot. One of eight slots for memory units on the processor and memory board
(PMB). The slots are labeled MS1 through MS8.
memory unit. A unit consisting of a dual inline memory module (DIMM) or a single inline
memory module (SIMM) that is installed in groups of four on the processor and
memory board (PMB) of the processor multifunction (PMF) customer-replaceable unit
(CRU). Memory units constitute the processor memory. The memory units in certain
models of PMF CRU are not replaceable by customers or in the field.
