ServerNet adapter
return reply messages to the clients or requesters. A server process is a running instance
of a server program.
ServerNet adapter. A customer-replaceable unit (CRU) that connects peripheral devices to
the rest of the system though a ServerNet bus interface (SBI). A ServerNet adapter is
similar in function to an I/O controller logic board (LB) and backplane interconnect card
(BIC) in other NonStop™ systems.
ServerNet addressable controller (SAC). A SAC corresponds to controller functionality
uniquely addressable within one or more ServerNet address domains through the node
ID and address fields in a request packet. A SAC is typically implemented on some
portion of a processor multifunction (PMF) CRU, an I/O multifunction CRU, or a
ServerNet adapter. Examples: Each of the controllers on a multifunction I/O board
(MFIOB) and Ethernet 4 ServerNet adapter (E4SA), and each of the controllers on a
device, connect to the ServerNet adapter.
ServerNet SAN. See ServerNet system area network (ServerNet SAN)
.
ServerNet system area network (ServerNet SAN). A wormhole-routed, full-duplex,
packet-switched, point-to-point network designed with special attention to reducing
latency and ensuring reliability. The ServerNet SAN provides the communication path
used for interprocessor messages and for communication between processors and I/O
devices.
ServerNet LAN Systems Access (SLSA) subsystem. The software that allows the protocol
I/O processes (IOPs) and drivers to access the ServerNet adapters.
ServerNet wide area network (SWAN) concentrator. The SWAN concentrator provides
data communications connectivity to a Himalaya S-series server system. The
concentrator supports both synchronous and asynchronous data over RS-232, RS-449,
X.21, and V.35 electrical and physical interfaces. Each SWAN concentrator has six
WAN ports. Traffic across these six ports is multiplexed over two 10-Mbps 10-baseT
ethernet connections.
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC), that
helps you resolve problems with your NonStop™ Himalaya S-series server. The TSM
package allows you to use the help of a service provider by configuring TSM to support
remote notification and remote access.
slot. A physical, labeled space for a customer-replaceable unit (CRU) or field-replaceable
unit (FRU) that is part of a module. A module contains one or more slots.
slot location. A three-number identifier for a particular slot on a system that consists of the
group number, module number, and slot number. EXAMPLE: 02,01,08 (group 02,
module 01, slot 08).
SLSA subsystem. See ServerNet LAN Systems Access (SLSA) subsystem
