Compaq RAID Array 4000 Storage System: Deployment and Configuration

Compaq Redundancy Manager (NT)

The Compaq Redundancy Manager software is a redundancy management solution, which
provides a range of functionality for servers using Fibre Channel storage. The software allows
configurations with redundancy to be built. The Redundancy Manager provides the ability to
configure the environment with redundant Fibre Channel Host Adapters.
Active/Active Host Adapters (NT)
In RA4000 Storage Systems, data is transferred from the server to the arrays and recalled via data
paths through each Fibre Channel Host Adapter. Since the system contains multiple data paths,
different configurations are possible. The Redundancy Manager automatically configures
multiple data paths with the first available path being set as Active and the next path as Standby.
However, the Redundancy Manager can be manually configured to have Active/Active paths to
allow load balancing of the system and to utilize multiple paths at the same time. After the
environment is configured, the Redundancy Manager provides redundancy and path management
in your configuration.
