The EMC Symmetrix disk arrays allow you to configure physical data replication solutions to provide disaster tolerance for Serviceguard clusters over long distances. This chapter describes the EMC SRDF software and the additional files that integrate the EMC with Serviceguard clusters. It then shows how to configure both metropolitan and continental cluster solutions using EMC SRDF.

The topics discussed in this chapter are:
