Control workstations
The SP/CES systems require a customer-supplied pSeries or RS/6000 system
known as a control workstation. The control workstation serves as a point of
control for managing, monitoring, and maintaining the SP/CES system frames
and individual processor nodes. A system administrator can perform these
control tasks by logging into the control workstation from any other workstation
on the network.
The control workstation also acts as a boot/install server for other servers in the
SP/CES system. In addition, the control workstation can be set up as an
authentication server using Kerberos. The control workstation can be the
Kerberos primary server, with the master database and administration service,
as well as the ticket-granting service. As an alternative, the control workstation
can be set up as a Kerberos secondary server, with a backup database, to
perform ticket-granting service.
Kerberos is no longer the only security method. The Distributed Computing
Environment (DCE) can be used with Kerberos V4, or by itself, or nothing (AIX
standard security).
A high availability solution may be implemented for the Control Workstation. The
solution is named the High Availability Control Workstation.
