ServerNet node routing ID

connected on the cluster switch. The ServerNet node number, which can be viewed

using the Subsystem Control Facility (SCF) or the OSM Service Connection, is unique

for each node in a ServerNet cluster.

ServerNet node routing ID. A bit field used to route ServerNet packets across the external

ServerNet X and Y fabrics. The ServerNet node routing ID occupies a portion of the

ServerNet ID, and it is unique for each member, or node, in a ServerNet cluster. This

term is the fully qualified form of node routing ID. The node routing ID determines the

node to which a ServerNet packet is routed.

SERVERNET object type. In the Kernel subsystem, the object type for either the $ZSNET

ServerNet subsystem manager process or the ServerNet X fabric or Y fabric.

ServerNet packet. The unit of transmission in a ServerNet communications network. A

ServerNet packet consists of a header, a variable-size data field, and a 32-bit cyclic

redundancy check (CRC) checksum covering the entire packet. The header contains

fields for control, virtual memory address, and destination and source fields to identify

the processor or I/O controller transmitting and receiving the packet. See also request

packet and response packet.

ServerNet port. A connector used for ServerNet links.

ServerNet router. An application-specific integrated circuit (ASIC) responsible for routing

ServerNet packets along ServerNet links in the ServerNet fabrics, using routing

information that is present within the packets. A ServerNet router acts as a fully duplex

crossbar switch, able to switch any of its input ports to any of its output ports.

ServerNet router 1. A ServerNet router that has a total of six input and six output ports.
