Storage DRS: Automated Management of Storage Devices in a Virtualized Datacenter
Virtualized datacenters contain a wide variety of storage devices with different performance characteristics and feature sets. In addition, a single storage device is shared among different Virtual Machines (VMs) due to ease of VM mobility, better consolidation, higher utilization and to support other features such as VMware Fault Tolerance (FT) and VMware High Availability (HA), that rely on shared storage. According to some estimates, the cost of managing storage over its lifetime is much more expensive as compared to initial procurement costs. It is highly desirable to automate the provisioning and runtime management operations for storage devices in such environments.
