Disaster recovery for multiple servers at multiple locations
As shown in the following figure, this distributed configuration is composed of two configuration distribution peers (CDPs) and two activity peers (APs), with the primary CDP and an AP in one data center and the HA-CDP and the second AP in the other data center. The grid is intentionally distributed geographically across intermediate physical networks, with the assumption that the physical network provides adequate bandwidth and low latency. Having two peers at each location ensures that the configured adapters have redundancy across the grid and at each location.
This configuration provides redundancy by having a CDP and AP in each data center and is usually deployed to satisfy disaster recovery requirements. This configuration is considered active/active; when a disastrous event causes the primary site to fail, the HA-CDP and second AP continue receiving and processing jobs and events. To enable forwarding of jobs to both sites, you must use routing technology that can detect the unavailability of either site and its peers. BMC recommends this deployment if you require job redundancy across two data centers.
To deploy this configuration, complete the following activities:
- Complete the following installation worksheets, and install the components in network A:
- Complete the following installation worksheets, and install the components in network B:
You can also download and complete the worksheets in an Excel workbook.
