Ensuring around-the-clock availability is a requirement today for all companies whatever their size. Although hardware has become very reliable, unplanned outages, resulting from non-hardware related problems, continue to occur: operator errors, software bugs, environmental conditions, disasters—problems that reliable hardware cannot prevent. Furthermore, planned outages for application and system maintenance also impact business performance..

Thanks to its solid expertise in AIX™ and its know-how in virtualization, consolidation and business continuity, Bull brings together the strengths of Bull Escala servers and high availability software, such as Bull ARF (Application Roll-over Facility), to provide customers with high availability solutions for critical applications and data. These solutions are designed with ease-of-maintenance in mind, while protecting economic and environmental interests

Bull’s high availability solution for Escala servers: easy-to-use and easy to maintain, designed to keep business critical applications operational

Application Roll-over Facility (ARF), Bull’s high availability software, helps provide application availaibility and minimize downtimes. ARF can be used for local and long-distance protection against any type of outage, including disasters. ARF provides low cost and easy to install and maintain application availability for the entire Escala range , including POWER6™ blades
ARF, appreciated for its ease of use, provides:

A scalable solution

Professional services

Furthermore ARF leverages Escala virtualization capabilities by dynamically increasing system resources to accommodate takeover workloads. When running in a small micro-partition on a backup server, ARF can automatically increase the system resources in the event of an application failover from the primary site.
