Building storage-agnostic disaster recovery solution using HPE Serviceguard for Linux

Introduction

With growing expectation in terms of reducing RTO as well RPO on diverse set of storage arrays, it has become imperative to have a capability that allows building solutions to automatically recover workloads with any underlying storage replication technology. This paper is about building such automatic disaster recovery solution using HPE Serviceguard for Linux.

Disaster recovery solution

Disaster recovery solutions are designed to build the ability to restore applications and its associated data within a reasonable period after a disaster hits the primary site. Most think of fire, flood, and earthquake as disasters, but a disaster can be any event that unexpectedly interrupts service in a data center. Disaster recovery solutions protect application against unplanned downtime due to such disasters by geographically distributing the nodes so that in the event of a disaster, availability of applications is not impacted.

HPE Serviceguard for Linux and storage-agnostic disaster recovery (SADR) capability

HPE Serviceguard for Linux (SGLX) is high availability (clustering) and disaster recovery software designed to protect applications availability from planned and unplanned downtime. HPE Serviceguard for Linux ensures 24x7 application availability by packaging an application or service with its associated resources and moving that package to other servers as needed. Such packages can be moved automatically when HPE Serviceguard detects a failure in a resource critical for functioning of the application or manually in order to perform system maintenance or upgrades. HPE Serviceguard for Linux also includes many out-of-the-box features that ensure scalability and allow intricate control over cluster configuration. More information about HPE Serviceguard can be found in the latest Release notes found at hpe.com/info/linux-serviceguard-docs.
