How Software-Defined Storage Software Works

SDS software abstracts the underlying storage through a virtual data plane; this makes the VM (and the application) the fundamental unit of storage provisioning and management.
By creating a flexible separation between applications and available resources, the pervasive hypervisor can balance all IT resources—compute, memory, storage, and networking—needed by an application.
What VMware Software-Defined Storage Solutions Deliver
Per-Application Storage Services
Ensure complete control of which storage services, and therefore costs, are consumed by each application. Since SDS works at the VM level, storage services can be tailored to precise requirements and adjusted as needed on a per-application basis—without affecting neighboring applications.
Rapid Changes to Infrastructure
Precisely match application demand and supply at the exact time the resources are needed with software-defined storage’s dynamic and non-disruptive model. Just like compute virtualization, storage services become fluid and accessible on an as-needed basis.
Heterogenous Storage Support
For leveraging of existing storage solutions, such as SAN, NAS, or direct attached storage, on x86 industry-standard hardware, SDS delivers complete flexibility. Using commodity servers—the backbone of hyperconverged infrastructure—enables design of low-cost and scalable storage environments.
