into slots in the SP Switch Router. In the same way that the SP Switch Router
Adapter connects the SP Switch Router directly to the SP Switch, these
networking cards enable the SP Switch Router to directly connect to an external
network. Network connections through SP Switch Routers are typically faster
and have better availability than network connections through the SP system
nodes.

1.4.4 Switches

The SP switches provide a message-passing network that connects all
processor nodes with a minimum of four paths between any pair of nodes. The
SP series of switches can also be used to connect the SP system with optional
external devices. A switch feature code provides you with a switch assembly and
the cables to support node connections. The number of cables you receive
depends on the type of switch you order.
The SP switches are available as either the 16-port SP Switch or the 8-port SP
Switch-8:
SP Switch2 (F/C 4012), 16-port switch (in SP systems exclusively with
POWER3 high nodes only)
SP Switch (F/C 4011), 16-port switch
SP Switch-8 (F/C 4008), 8-port switch
For more information, refer to Chapter 5, "The Switch" on page 159.

1.4.5 Control workstations

You can view the SP/CES control workstation, as a server to the SP/CES system
applications. The subsystems running on the CWS are the SP/CES server
applications for the SP/CES nodes. The nodes are clients of the CWS server
applications. The CWS server applications provide configuration data, security,
hardware monitoring, diagnostics, a single point of control service, and
optionally, job scheduling data and a time source. The CWS is an pSeries or an
RS/6000 system. The available pSeries and RS/6000 systems which are
supported as CWS are as follows:
^ pSeries 660 Model 6H1 (7026-6H1)
^ pSeries 620 Model 6F1 (7025-6F1)
RS/6000 Enterprise Server Model H80 (7026-H80)
RS/6000 Enterprise Server Model F80 (7026-F50)
