Pershing Limited wanted to protect its key business services from unplanned downtime – while limiting the amount of manual processes and risk associated with the disaster recovery process. After working with Pershing Limited to understand its business continuity requirements, Unisys deployed an automated failover solution that enables the company to quickly restore operations in the event of a disaster or disruption.
By working with Unisys to address its most pressing availability requirements, Pershing was able to significantly reduce failover times – and do so with limited risk and manual intervention. Pershing Limited, a BNY Mellon company, provides a comprehensive range of business solutions for institutional broker-dealers, private wealth firms, and independent financial advisers in Europe. In providing global execution and settlement services, the reliability and availability of the supporting IT services are paramount. This includes the provision of effective disaster recovery (DR) processes.
Pershing first invested in metered Unisys ClearPath® systems in 2006 and deployed EMC® Symmetrix® disk subsystems with EMC Symmetrix Remote Data Facility® (SRDF) to provide synchronous mirroring between primary and secondary data centers, thereby ensuring no loss of data in the event of an unexpected outage. However, the steps needed to modify the backup system’s configuration to take on the production workload took several hours and required risky, error-prone manual processes. For example, a failover test that began at 7 p.m. could last until 2 a.m. the following morning before the backup system was ready to run the production nightly batch processes.
Unisys Business Continuity Accelerator software helps Pershing automate the DR processes for its mission-critical IT services. Business Continuity Accelerator seamlessly transfers the personality of the live system to the backup system – replicating all disk volumes, including the boot “Halt/Load” unit – enabling the software to establish the entire disk environment on the backup system.
This process helps Pershing eliminate the need to manually reconfigure its backup system or modify individual options, settings, and file names. With Business Continuity Accelerator, the entire disk image, including the MCP operating system and its configuration files, is transferred – not just the primary databases and code files – so there is no need to perform any manual configuration tasks.
