SCSI ServerNet
addressable
controller (S-SAC)
A ServerNet addressable controller (SAC) that is contained within a small computer system
interface (SCSI) plug-in card (S-PIC).
serial copper
plug-in card (PIC)
A
for the modular ServerNet expansion board (MSEB) and I/O multifunction
(IOMF) 2 customer-replaceable unit (CRU) that supports the serial copper interface.
serial ZX1 I/O link
The cable that connects the LSU and the processor element.
server
A computer system used as a standalone system or as a
in a network.
Server is a synonym for
.
ServerNet adapter
A
customer-replaceable unit (CRU)
that connects peripheral devices to the system through a
ServerNet bus interface.
ServerNet
addressable
controller (SAC)
A controller that is uniquely addressable within one or more ServerNet address domains (SADs)
through the node ID and address fields in a request packet. A SAC is typically implemented on
some portion of an
I/O multifunction 2 (IOMF2) CRU
or a
.
ServerNet cluster
A network of servers connected using the ServerNet protocol and sharing a common transport
for interprocessor communication across and within a cluster. It offers fast end-to-end communication
without intermediate protocol stacks, achieving comparable speeds for internal and external
ServerNet communication.

ServerNet II switch
A 12-port network switch that provides the physical junction point to enable an NonStop S-series
server to connect to a ServerNet cluster. The ServerNet II switch is a component of the
ServerNet PIC
One of several types of plug-in cards that provide ServerNet connectivity for different components
within an HP NonStop NS-series server. ServerNet PICs include:
•
A cluster PIC in slot 2 for connecting a NonStop NS-series server to a ServerNet cluster
•
I/O PICs in slots 4 though 9 for connecting to an IOAM enclosure or a NonStop S-series
I/O enclosure
•
Processor PICs in slots 10 through 13 for connecting to the processors in a NonStop NS-series
processor complex
•
Crosslink PICs in slot 3 for connecting the X-fabric and Y-fabric p-switches to each other
ServerNet router
An application-specific integrated circuit (ASIC) responsible for providing interconnection of
ServerNet links in a
ServerNet system area network (ServerNet SAN)
. A ServerNet router is never
an end device.
ServerNet Switch
Board
The component in a processor switch that provides the switching logic. The board has a front
panel with a liquid-crystal display (LCD) for operator and maintenance functions.
ServerNet system
area network
(ServerNet SAN)
A low-cost, high-speed network, contained within a system, that connects processors to each other
and to ServerNet addressable controllers (SACs).

ServerNet wide
area network
(SWAN) 2
concentrator
An HP data communications peripheral that provides connectivity to an HP NonStop server. The
SWAN 2 concentrator supports both synchronous and asynchronous data over RS-232, RS-449,
X.21, and V.35 electrical and physical interfaces. The SWAN 2 concentrator is the next-generation
SWAN concentrator and has 12 WAN ports.
ServerNet wide
area network
(SWAN)
concentrator
1. An HP data communications peripheral that provides connectivity to an HP NonStop server.
The SWAN concentrator supports both synchronous and asynchronous data over RS-232, RS-449,
X.21, and V.35 electrical and physical interfaces.
2. A collective term for both SWAN concentrators and SWAN 2 concentrators when a distinction
between the two is not required.
ServerNet/FX 2
adapter
A ServerNet adapter that logically extends the ServerNet X and Y fabrics to other clusters in a
Fiber Optic Extension (FOX) ring by using fiber-optic lines. Two 6742 ServerNet/FX 2 adapters
are used, one for the X ring and one for the Y ring.
