Credit Card Application Availability to Survive Disasters
The largest U.S. processor of credit card transactions provides ATM and point-of-sale (POS) card management services for a variety of financial and commercial firms on HPE NonStop systems.
- The original configuration was vulnerable to failure and needed an easy to implement and reliable disaster recovery solution.
- The customer required flexibility in the database mappings to allow for differing file/table partitioning layouts between the source and target systems.
Figure 1 — HPE Shadowbase Active/Passive Disaster Recovery Architecture
Figure 1 depicts the processor’s new architecture: the CMA users update the active, HPE NonStop source server, and Shadowbase uni-directionally replicates the database changes to the passive, HPE NonStop target server. If the primary system fails, the IT team can disconnect the users from the active server, start the applications on the target node, and connect them to the passive backup server.
- Increased availability through fast and reliable failover when disaster takes out the primary system/datacenter
- Full customer flexibility for target file/table partition and schema format and location mapping
- The customer is well-positioned to consider the more advanced business continuity architectures that HPE Shadowbase software supports for future needs, for example, sizzling-hot-takeover (SZT) or active/active (A/A)
