Resilient Hosting of Research Data Management Services

Abstract: High Availability (HA) environments achieve automatic failover to prevent data loss and minimize downtime while ensuring stability. The cost-effective and flexible HA setup avoids technology lock-in through its use of open-source components and virtual machine clusters. The system relies on two main components, which are the Pacemaker and Distributed Replicated Block Devices (DRBD). DRBD maintains real-time data replication, which results in backup servers obtaining exact copies of the primary server data. The Pacemaker system functions as a cluster manager to handle server cluster problems by performing automatic failover operations. The fencing mechanism of this system blocks simultaneous data access to prevent data corruption while maintaining data integrity. The HA setup provides scalability features that enable research environments to handle increasing data volumes, user numbers, and workflow demands through server additions or configuration modifications.
