Processor Switch
The processor switch, or p-switch, provides the first level of ServerNet fabric
interconnect for the Integrity NonStop NS-series processors. ServerNet connection
from the LSU also defines the ID numbers, 0 through 15, for the logical processors
within the system. In cases where NonStop S-series I/O enclosures provide I/O
capabilities and storage for the Integrity NonStop NS-series system, the ServerNet
connection to the p-switch determines the NonStop S-series I/O enclosure group
number, as described in NonStop S-Series I/O Enclosure Group Numbers on
page 5-32.
