The HP StorageWorks Enterprise Virtual Array (EVA) allows you to configure data replication solutions to provide disaster tolerance for Serviceguard clusters over long distances. This chapter describes the Continuous Access EVA software and the additional files that integrate the EVA with Serviceguard clusters. It then shows how to configure metropolitan cluster solutions using Continuous Access EVA.

The topics discussed in this chapter are:
