The HP Virtual Server Environment: Making the Adaptive Enterprise Vision a Reality in Your Datacenter

Summary

Since my initial encounter with the NASA engineer who told the story about engineers wearing both a belt and suspenders, I've learned that the phrase is commonly used when referring to systems designed with a high degree of fault tolerance and redundancy. HP Serviceguard provides the belt and suspenders for workloads. Serviceguard clusters can be configured to host numerous packages and regardless of whether a node experiences a failure, the package can continue operations on an adoptive node. The result is highly available workloads with hardware and software fault tolerance.

Serviceguard can be configured in large or small clusters. As was shown in this chapter, a cluster can be configured in an environment as simple as a primary node ...
