HPE Serviceguard for Linux

What’s HPE Serviceguard for Linux

HPE Serviceguard for Linux (SGLX), a high availability(HA) and disaster recovery (DR) clustering solution, increases uptime for your critical applications by protecting them from a multitude of infrastructure and application faults across physical or virtual environments over any distance. It reduces the impact of unplanned downtime with no compromise on data integrity and performance. Furthermore, it helps achieve near zero planned downtime for maintenance.

HPE Serviceguard for Linux is a high availability clustering software designed to protect applications and services from planned and unplanned downtime.

HPE Serviceguard for Linux (SGLX) ensures 24×7 application availability by continuously monitoring the health of the infrastructure and other resources impacting availability of the workload or service within a cluster. It packages an application with its associated resources and moves the package automatically to other server (nodes) in the cluster in the event of a failure that affects any the resources required by the protected workloads. Packages can also be moved manually to perform system maintenance or upgrades. SGLX quickly responds to failures such as those that affect the server, storage, network, SAN & LAN connectivity, processes, memory, disk, operating environments, and more.

HPE Serviceguard for Linux includes out-of-the-box Integration called Toolkits for several popular enterprise grade applications to enable quick integration of such complex applications into a Serviceguard cluster. The Application Integration Toolkit portfolio includes integration for business software and databases like SAP HANA, S/4 HANA, NetWeaver, Oracle, Microsoft SQL Server, and IBM Db2 among others. SGLX also offers Toolkits for open source applications and databases like NFS, My SQL, Postgres, Apache, and Tomcat among others which are available at no charge.

In addition to high availability within a data center, Serviceguard for Linux offers a powerful and comprehensive suite of disaster recovery (DR) solutions. SGLX provides a choice of both fully automatic and push button recovery solutions that are tightly integrated with several array based, host based and Database native replication technologies.
