Processor Multifunction (PMF) CRUs
The processor numbers and fabric connections:
The even-numbered processor in slot 50 can also communicate with the Y fabric
through its router and the processor in the other PMF CRU in the same enclosure.
The odd-numbered processor in slot 55 can also communicate with the X fabric
through its router and the processor in the other PMF CRU in the same enclosure.
Processor types for NonStop S-series servers are listed in Processor Types on
page B-12.
Secondary Cache
The amount depends on the model of the PMF CRU.
Memory
Memory consists of memory units. The PMB has eight memory slots, MS1 through
MS8, and each memory unit is identified by its slot number.
The memory for a processor is organized into two logical memory units (LMUs) of four
memory units each.
One LMU consists of memory units in slots MS1 through MS4; the other LMU consists
of memory units in slots MS5 through MS8. An LMU must have memory units installed
in either all of its slots or none of its slots.
All memory units within an LMU must be the same size, but the two LMUs on a PMB
can be different sizes.
Memory units are not compatible between different models of customer-replaceable
PMF CRUs.
For NonStop S7600 and S74000 PMF CRUs and later, memory for a processor is
organized differently; each memory unit is its own LMU.
Memory units are field-replaceable only for NonStop S7000 and S70000 servers. To
repair or upgrade memory in other servers, you must obtain a replacement PMF CRU
from HP.
The supported memory configurations are:
