Processor Switch
The processor switch, or p-switch, provides the first level of ServerNet fabric
interconnect for the Integrity NonStop NS16000 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 NS16000 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 5-37.
Two p-switches are required, one each for the X and Y ServerNet fabrics. Physical
attributes for the 3U-high p-switch are:
•
Rackmountable
•
Dual AC power feeds and power supplies
•
Dual fans with front to rear cooling
•
Main logic board
•
Maintenance entity (ME) logic and firmware
•
Maintenance PIC (slot 1) for connection to maintenance switch
•
Cluster PIC (slot 2) for connection to 6770 or 6780 cluster switch
•
Crosslink PIC (slot 3) for connection to the other p-switch
