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.

HPE Serviceguard Key Features

Fast Failover and Protection in the Data Center

HPE Serviceguard for Linux monitors the availability of critical resources and applications, and provides fast failover in the event of a failure, in as little as 4 seconds without comprising on data integrity.

Combined with HPE Serviceguard Extension for SAP, it reduces the need for manual intervention and downtime in case of unplanned and planned failures for critical SAP HANA® databases.

4X faster deployment, reduces setup time from days to hours with 93% reduction in setup time. HPE Serviceguard for Linux offers out-of-box integration for several applications that enables easy deployment with no added customizations.

Achieves higher uptime in virtual environments with application failovers rather than virtual machine restarts. HPE Serviceguard for Linux supports VMware® and KVM hypervisors.

Monitors the availability of applications, services, databases, and platforms over distances, while protecting against outages and reducing downtime during planned maintenance windows.

Stay Available During Site Outages

HPE Serviceguard for Linux disaster recovery (DR) solution keeps your application online even after the loss of a data center over any distance (providing) with a choice (range) of responses from fully automatic failover to push button recovery.

Fully automatic recovery for complex, scale-out workloads like HANA using site aware disaster tolerant architecture (SADTA) that provides robustness, resiliency and availability for your applications and services.

Offers a suite of disaster recovery solutions for different choice points based on distance, data replication and Recovery Point Objective (RPO) and Recovery Time Objective (RTO) RPO/RTO to fulfill a wide array of conditions.

Reduces capital expenditure with flexible deployment models that allows for minimal reduced investment and enables consolidation of standby resources.

Near Zero Downtime Maintenance

HPE Serviceguard for Linux offers a Live Application Detach (LAD) feature that allows you to do maintenance of the HPE Serviceguard cluster infrastructure (including the heartbeat network) with almost zero downtime.

Rolling upgrades enable upgrade of infrastructure components, operating system, and applications with reduced downtime.

No Compromise Data Integrity and Easy Administration

HPE Serviceguard for Linux delivers proven algorithms and superior arbitration mechanisms providing high levels of availability, data integrity and reliability.

Offers efficient fault detection capabilities that automatically failover critical applications to safer nodes and that resume normal operations without compromising data integrity.

Allows users you to visually configure, monitor, manage, and administer a cluster and its components (such as nodes or packages). Intuitive color-coded icons quickly identify problems with the cluster so user you can quickly react and resolve issues.

HPE Serviceguard Editions

The HPE Serviceguard for Linux portfolio is now available in three easy to order editions to keep you protected:

HPE Serviceguard Toolkits and Extensions for Linux

Enterprise applications and databases can be very complex, and appropriate handling when those services crash, hang, or restart is critical to rapid and transparent recovery. HPE Serviceguard Toolkits and Extensions for Linux greatly simplify and accelerate the integration of complex applications into a standardized and proven framework. They handle initial integration of these applications into a cluster as well as provide ongoing monitoring, failover, and failback operations of the clustered application. This means you get it done right and faster—and save up to 93 percent on time and effort versus doing it yourself.

HPE SGLX DR Offerings

HPE Serviceguard for Linux provides a rich suite of DR offerings based on multiple replication technologies to suit different needs and environments.

  1. Extended Distance Cluster (XDC): Entry level DR offering where the data is replicated between the primary and secondary data centers using host based replication software’s such as LVM, VxVM and MD Raid Mirroring. SGLX monitors and manages the application and the underlying replication to provide RPO sensitive automatic, bi-directional recovery.
  2. Metrocluster (MC): Provides automatic, bi-directional failover and failback across data centers up to several hundred kilometers/miles apart (up to any distance where the round trip network latency is no more than 200 ms). The data is replicated between the primary and secondary data centers using array based replication (3PAR remote copy, EMC SRDF, XP & EVA continuous access). Serviceguard monitors and manages both the application and the underlying replications to provide contextual RPO sensitive recovery
  3. Continentalclusters (CC): DR solution that can stretched across unlimited distance, provides push button automated recovery and cluster level redundancy. In case of failure of the primary data center the entire cluster is recovered in the secondary data center. Provides many to one recovery capabilities with ultimate flexibility of using any replication technology for data replication.
