Server Virtualization and Storage Disaster Recovery Ray Lucchesi, President, Silverton Consulting Server virtualization demands increasingly sophisticated storage subsystems. To support disaster recovery (DR) in virtual server environments storage admins need to understand how I/O and storage layouts in these environments differ from non-virtualized server storage. In addition, some server virtualization systems in order to automate DR can make use of special storage subsystem capabilities unique to these environments. The tutorial will describe the unique server virtualization I/O and storage layout requirements as well as to discuss some DR storage considerations under these environments. DR in server virtualization environments requires re-thinking some of the DR-storage assumptions that have worked in past environments. Also, new server virtualization software and other tools are becoming available to held automate the DR processes. The extent of DR automation provided by these tools depends on storage subsystem capabilities. When and where to use these tools will be discussed.
