Version 1.6

DESCRIPTION

TruCluster™ Available Server Software Version 1.6

for Tru64 UNIX (formerly known as DIGITAL

UNIX)

is part of the Tru64 UNIX TruCluster product suite.

The TruCluster product suite consists of Production

Server Software, Available Server Software, and

Memory Channel

Software. The Memory Channel

Software product provides high-performance data

delivery for applications over the Memory Channel

interconnect. The Available Server Software product

provides high availability for applications. These

capabilities combine in the Production Server

Software to provide a high-performance, highly

available, and scalable operating environment.

TruCluster Available Server Software significantly

reduces downtime due to hardware and software

failures. A TruCluster Available Server Software

environment is an integrated organization of systems

and external disks and tape devices connected to

shared SCSI buses that together provide highly

available software and disk data and tape service to

client systems.

TruCluster Available Server Software is a high

availability solution that minimizes, but does not

eliminate, the impact of hardware and software

failures. It is designed for computing environments

that can tolerate a short disruption, but need critical

applications automatically restarted.

TruCluster Available Server Software provides multi-

host access to SCSI disks and a generic failover

mechanism for disks and applications. In this

environment, system administrators can set up

services that make disks and applications highly

available to client systems. For example, services

may be set up for exported NFS file systems, raw

disks, and disk-based applications such as database

programs or mail. Services may also be set up as

non-disk-based applications such as a remote login

service. TruCluster Available Server Software

provides all the necessary software to fail over disks

on a shared SCSI bus. To fail over an application,

shell scripts are created that the software executes to

stop the application and restart it on another host.

The systems connected to the shared bus run the

services. Client systems may access a service

through the network to the system on which it is

running. Each system can run every service and fail

over all the disks on the shared bus. A service runs

on only one system at a time, and can automatically

be restarted on another system in the event of a

device or system failure with the proper hardware

configuration.

Each system within the TruCluster Available Server

Software environment monitors the networks and the

status of the systems, disks, and buses. If a hardware

or software failure prevents a system from running a

service, TruCluster Available Server Software

automatically moves (relocates) the service to

another system to maintain the availability of the

applications and disks. A service can optionally have

Internet protocol addresses assigned to it to provide

transparent access to clients.

TruCluster Available Server Software provides the

ability to manually relocate a service from one system

to another when needed to perform maintenance or

load balancing on a system. In addition,

administrators can update a service’s storage

configuration as well as other service information in

the service configuration without interrupting a

service’s availability to clients. TruCluster Available

Server Software enables connection of systems and

disks and tapes to the shared bus so that

modifications may be made to the hardware

configuration without affecting the environment.

FEATURES

Concurrently Active Servers

If there are as many services as there are systems in

a TruCluster Available Server Software environment,

then each member can run a service. This enables all

systems to optimize workload, eliminating idle time

for any systems.
