This paper presents automated planners that can assist administrators in making intelligent placement and resiliency decisions when provisioning for both new and existing applications. Introducing an application into a data center involves complex interrelated decision-making for the placement of data (where to store it) and resiliency in event of a disaster (how to protect it). We propose planners that take advantage of recent improvements in storage resource management and provide guided recommendations based on monitored performance data and storage models. The IBM Provisioning Planner provides intelligent decision-making for the steps involved in allocating and assigning storage for workloads. It involves planning for the number, size, and location of volumes based on workload performance requirements and hierarchical constraints, planning for the appropriate number of paths, and enabling access to volumes using zoning and mapping/masking. The IBM Disaster Recovery (DR) Planner, VISHNU, enables administrators to choose and deploy appropriate replication technologies spanning servers, the network, and storage volumes to provide resiliency to the provisioned application. VISHNU begins with a list of high-level application DR requirements and creates an integrated plan optimized on criteria such as cost and solution homogeneity. VISHNU also deploys the DR plan and orchestrators that execute failover and failback.
