In this White Paper “Turning Object Storage into Virtual Machine Storage” we discuss Object Storage as storage solution for Virtual Machines. Due to technical hurdles it is impossible to run Virtual Machines directly from an Object Store. The main issues are eventual consistency, performance and latency and different management paradigms. A distributed file system is also no fit for the job.
To turn Object Storage into primary storage for hypervisors, the solution must be especially designed for Virtual Machines and take a radical different approach compared to existing storage technologies. Open vStorage takes this different approach and is designed from the ground up with Virtual Machines and their performance requirements in mind. Open vStorage is the layer between the hypervisor and Object Store and turns the Object Store into a high performance, distributed, VM-centric storage platform.
