Continuous Availability Administration

Continuous Availability Administration
This section describes a Continuum system’s unique continuous-availability
architecture and provides an overview of the special tasks system administrators
must perform to support and monitor this architecture.
Continuum Series 400/400-CO Systems
Stratus offers two models of Continuum Series 400 systems: a standard
(AC-powered) model designed for general environments, and a central-office
(DC-powered) model designed for central office environments. Continuum Series
400 and 400-CO systems include the following features:
■ A pair of suitcases that integrate processors, memory, console support, power,
and cooling in a single customer-replaceable unit (CRU).
■ Two card-cages (sometimes called bays) built into the system base or cabinet
that are electrically isolated from each other. Each card-cage contains eight
slots for peripheral component interconnect (PCI) I/O cards.
■ A storage enclosure built into the system cabinet that houses disks;
central-office models support two storage enclosures.
■ Two power supplies and, if the system is connected to an uninterruptible
power supply (UPS), flexible powerfail recovery options.
■ Multiple, variable-speed fans that automatically adjust to environmental
conditions.
See the HP-UX Operating System: Continuum Series 400 and 400-CO Operation and
Maintenance Guide (R025H) for a complete description of the Continuum Series
400/400-CO architecture and components.
