IBM is responding to your tremendous interests in high availability and business continuity. With IDS V11.50, you will be able to deploy High-availability Data Replication (HDR) with no additional feature charge for the Workgroup Edition, deploying up to two secondary servers in either Idle standby or Hot active read mode. Hot active secondary servers are now eligible for sub-capacity pricing on the Processor Value Unit metric.
