Storage replication is one of the back bones for network environments. While many forms of Network Attached Storage (NAS), Storage Area Networks (SAN) and other forms of network storage exist, there is a need for a reliable storage replication technique between distant sites (> 1 Km). Such technology allows setting new standards and removes demerits of network failover and failback systems for virtual servers; specifically, the growing storage need for effective disaster recovery (DR) planning. The purpose of this manuscript is to identify growing technologies such as IP-SAN that allow with remote storage cluster replication for virtual servers. This study (Cluster Replication) provides an analysis of improving the uptime and availability of SAN. For higher levels of availability, mirrored images maintained in Active/Active Cluster mirroring can provide a system with No Single Points of Failure, which is designed to improve the overall uptime of the storage system for organizations with 7x24x365 requirements.
