With decades experience supporting the most mission-critical deployments of HP-UX anywhere in the world, Beechglen has maintained an unmatched reputation of reliability and trust in complex/critical ServiceGuard environments.
What is MC/ServiceGuard? and what service is provided on this software?
MC/ServiceGuard Support indicates proactive and reactive support will be provided on both the HP-UX OS environment and layered software products being utilized in a completely redundant, mission-critical environment in which the enterprise utilizes their HP9000 and Integrity servers.
With HP Serviceguard, multiple server nodes and/or server partitions are organized into redundant enterprise clusters that deliver highly available application services to network attached clients. Serviceguard monitors the health of each node and rapidly responds to failures in a way that minimizes or eliminates application downtime. The HP-UX operating system is integrated between the Processor Dependent Code (PDC) and the Serviceguard Clustering Environment which provides reliable redundancy and fail-over to these mission critical servers. The PDC is far more than BIOS and its integration with HP-UX provides high-end server performance that could not be achieved in an OS alone.
In a 100% MC/ServiceGuard redundant environment, system failures are more complex than standalone HP-UX servers. Additional realms of problems occur based on layered products, clustering dependencies of multiple servers, and disaster recovery fail-over. These dependencies also exist at the patch level, ensuring those patching dependencies are interoperable when applied to a single server and its failover cluster.
With high-end corporate-critical database servers that measure application downtime in mere minutes per year, unique specialized support expertise is required to see through server-level changes to fail-over dependent systems and subsystems. Each server instance and server cluster is a unique accumulation of an OS base release and thousands of patches. Each support instance, hw/sw failure, or change requires careful attention and tools for patch dependency analysis for each server, each subsystem, all hardware components and all applications.
