Reliability and Serviceability Features

Reliability, availability, and serviceability are key requirements for platforms running business-critical application services. In today’s globally competitive environment, where users access applications round-the-clock, downtime is unacceptable and can result in lost customers, revenue, and reputation. The BladeSymphony 1000 is designed with a number of features intended to increase the uptime of the system.

Reliability Features

Intended to execute core business operations, the BladeSymphony 1000’s modular design increases reliability through the high availability of redundant components. Rather than focus on creating individual highly available components, the BladeSymphony 1000 utilizes multiple industry-standard components to cost-effectively increase reliability. Redundant components also increase the serviceability of the system by allowing the system to continue operating while new components are added or failed components are replaced.

The BladeSymphony 1000 is designed with features to help ensure the system does not crash due to a failure and to minimize the effects from a failure. These features are listed in Table 11.
