An important note on third-party mass storage

HP only tests HP mass storage devices to verify that they meet HP Serviceguard Solutions’ high availability requirements, therefore full support is provided for these devices only. The sole exception to this is EMC Symmetrix disk arrays. All mass storage devices listed on this web page are fully supported (with noted exceptions where appropriate) for use with Serviceguard.

Some third party mass storage has been tested for basic functionality with HP Serviceguard, and these devices can be supported for use in Serviceguard clusters if an allowance is granted for the configuration by HP. These devices are listed in the Third Party Storage

Interoperability matrix at: http://www.hp.com/products1/unixserverconnectivity/mass_storage_devices.html. See the details at the bottom of that web page for information on how to request an allowance.

There you will find a matrix of third party mass storage devices supported on HP-UX, which also indicates whether or not the device is supported for HP Serviceguard. Please note that the mass storage devices listed as supported with HP Serviceguard on this web page are not fully supported in that HP has not fully tested them and cannot guarantee that they meet all of HP Serviceguard availability requirements. For support

of a cluster with these third party mass storage devices, the third party device vendors, rather than HP, will take the lead in the support of their mass storage devices with HP Serviceguard.

If you wish to obtain support for a mass storage device listed in the Third Party Storage Interoperability matrix, please contact your HP representative and request to have an allowance for support of the device.

UX Serviceguard High Availability Software specifications

HP-UX Serviceguard is a powerful high availability (HA) software solution designed to ensure that mission-critical applications remain accessible and operational in the event of hardware or software failures. Built for the HP-UX operating system, it plays a crucial role in maintaining business continuity by providing automated failover capabilities, minimizing downtime, and protecting valuable data.

One of the core features of HP-UX Serviceguard is its ability to monitor the health of system resources and applications. It continuously checks the status of critical components, and in the event of a detected failure, it automatically initiates failover processes. This means that system resources can be switched to backup servers seamlessly, allowing for uninterrupted access to services and applications.

Serviceguard utilizes a cluster-based architecture, which consists of multiple nodes that work together as a single system to ensure high availability. Each node can take over the resources of another node in case of a failure. This configuration provides redundancy and resilience, ensuring that if one node goes down, the others can maintain operations without any significant impact on performance.

Another standout feature of HP-UX Serviceguard is its support for various applications and databases. It is compatible with popular enterprise applications, making it a versatile solution for businesses with diverse IT environments. The software is optimized for a range of database and web applications, providing tools for seamless integration and management.

Serviceguard's advanced configuration options allow administrators to create custom failover policies based on specific business needs. This flexibility means that organizations can tailor their high availability solutions to meet the demands of their unique IT ecosystem. Furthermore, Serviceguard supports both active-active and active-passive clustering configurations, enabling businesses to choose the level of availability that suits their operational requirements.

In terms of data protection, HP-UX Serviceguard offers features such as file system replication and backup capabilities. It integrates with storage systems to provide comprehensive data recovery options. Additionally, its scripting and automation tools help streamline management tasks, reducing the operational burden on IT teams.

Overall, HP-UX Serviceguard stands out as a robust high availability solution, offering a comprehensive set of features, technologies, and characteristics that empower organizations to maintain business continuity. With its cluster-based architecture, application support, customizable policies, and data protection mechanisms, Serviceguard is an essential tool for enterprises relying on HP-UX for their critical workloads.
