It is increasingly difficult for organizations to separate business concerns from IT, particularly IT that supports their most critical services. Because these services are integral to the businesses they serve, downtime costs can be alarmingly high. This situation is true whether the downtime is planned or unplanned, but unplanned downtime can be particularly damaging because it often affects organizations' reputations in addition to their bottom lines, even when durations are measured in mere minutes. It is little wonder that most organizations do not consider unplanned downtime an option.
You can address the three most common reasons for unplanned downtime with a solution that combines IBM® z Systems™, SUSE Linux Enterprise Server for System z®, and two extensions for SUSE Linux Enterprise Server: SUSE Linux Enterprise High Availability Extension and Geo Clustering for SUSE Linux Enterprise High Availability Extension.
This IBM Redguide™ publication provides a business-level discussion that enumerates the three main reasons services become unavailable and systems go down. It also explains the business ramifications of unplanned downtime and the benefits of implementing a high availability solution that includes z Systems, SUSE Linux Enterprise Server for System z, SUSE Linux Enterprise High Availability Extension, and Geo Clustering for SUSE Linux Enterprise High Availability Extension. It then describes this solution in more detail within the context of the three main reasons for unplanned downtime. Finally, it provides links and contact information if you want to learn more.
