Using HP Global Workload Manager with Serviceguard

Serviceguard packages provide a simple, flexible framework for managing application resources.

You can create up to 150 packages; multiple packages can run on each of the nodes within the

cluster. Figure 1 illustrates example components of a Serviceguard package.

Technologies Built on HP Serviceguard

A typical Serviceguard configuration consists of nodes in a single data center—referred to as a local

cluster. Creating clusters that are resistant to multiple points of failure or single massive site failure

requires a different type of cluster architecture than that used in a local cluster. This architecture is

called a disaster-tolerant architecture—often referred to as a disaster-tolerant solution (DTS). This

architecture provides you with the ability to fail over automatically to another part of the cluster or

manually to a different cluster after certain disasters. Specifically, the disaster-tolerant cluster provides

appropriate failover when an entire data center becomes unavailable. HP has a rich portfolio of

disaster-tolerant cluster offerings, including HP Extended Campus Cluster, HP Metrocluster, and HP

Continentalclusters. While each of these solutions has its own characteristics, their common goal is to

protect users from a site-wide outage. To achieve this, the common feature they all implement is

multiple data centers with multiple copies of the users’ data. Effectively, if one data center fails, a

second data center is available to continue processing.

What is HP Instant Capacity?

HP Instant Capacity provides the ability to increase processing capacity instantly on various HP

enterprise servers. With Instant Capacity, you initially purchase a specified number of active and

inactive system components. The inactive Instant Capacity components are available for instant

activation. Instant Capacity increases processing power in a matter of minutes. It can also provide

high availability of your system: Upon detection of processor failure, a second processor can be

instantly activated.

HP also offers Temporary Instant Capacity (TiCAP), which enables you to prepare for demands on

your system resources by ordering a 30 processing-day block of temporary capacity for any system
