In an increasingly competitive business

environment, the availability of information

often makes the difference between success

and failure. Unfortunately, all the planning

and maintenance in the world cannot prevent

an application or server from crashing.

Statistics show that it is not a question of 

if systems will fail, but when. Such failures

can shut down a production infrastructure

and your business. System downtime all too

often results in lost business opportunities,

dissatisfied customers and damage to your

company’s reputation. In today’s time-critical,

web-enabled marketplace, it is imperative

that critical business continues uninterrupted.

BrightStor High Availability from Computer

Associates International, Inc. (CA) enables

continuous business operations and is a

necessary component of any data protection

and availability plan. Once critical data and

applications are defined through the setup

wizard, they are automatically replicated to 

a secondary server in real time. This replication

occurs continuously as changes and updates

occur, providing the secondary server with

all the critical information in case the primary

server suffers catastrophic damage.

BrightStor High Availability can automatically

detect services and server failures, and

instantly switch end users to the secondary

server, whether that server is local or remote.

The secondary server assumes the complete

identity of the primary server — including 

its host name and IP address — as well as

continuing to process its normal workload.

The entire failover process occurs in real

time and is completely transparent to the

end users.

BrightStor High Availability offers the

following benefits:

• High Scalability and Flexibility. BrightStor

High Availability scales to support 

networks of any size. It runs on any 

networked Windows 2000 or Windows

Server 2003 Server and does not require

any special hardware, network cards or

unique configurations. As your organization

grows, protection can be extended to

additional primary servers at any time.

• Efficient, Cost-Effective Protection.

Multiple primary servers can replicate to

a single secondary server, offering more

efficient use of available resources. The

primary and secondary servers need not

be identical and can be located anywhere

in the network.

• Complete Out-of-the-Box Protection.

BrightStor High Availability includes built-in

support wizards for popular applications

that users continually access, including

databases, groupware and web-based

applications. If BrightStor High Availability

detects a potential failure, it can seek 

confirmation by checking an optional serial

port link between the primary and secondary

servers, and by “pinging” selected network

machines or devices.

High Availability protects mission-critical data and applications in

Windows 2000 and Windows Server 2003 environments by replicating them to a

local or remote secondary server. Data is synchronized between the two servers

in real time with patented technology that maximizes data and transactional

integrity while optimizing performance and availability. In the event of an application

or server failure, BrightStor High Availability provides users with nonstop access

to data and applications without significantly increasing the IT budget.
