Sun Cluster Geographic Edition Overview

Hitachi TrueCopy Software

The Hitachi TrueCopy software is a storage-based replication facility that provides a host-independent data replication for geographically separated clusters. Hitachi TrueCopy software enables the primary volumes to remain online for all hosts and while processing both read and write I/O operations. If a disaster or system failure occurs, the secondary copy of the data can be run for a recovery with minimal loss of data. For more information about the Hitachi TrueCopy software, see the product documentation.
