Synchronous replication of remote storage

Dr. Timur Mirzoev

Storage replication is one of the essential requirements 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 synchronous storage replication technique between distant sites (less than 1 mile). Such technology allows setting new standards for network failover and failback systems for virtual servers; specifically, addressing the growing need for effective disaster recovery (DR) planning. The purpose of this manuscript is to identify newest technologies such as SAN/iQ and Storage VMotion that allow for remote storage synchronous replication for virtual servers. This study provides an analysis and a comparison of various SANs that create solutions for enterprise needs. Additionally, the interoperability of these technologies with the industry s leading product VMware ESX Server will be discussed.
