Dell EMC Networking OS10 Enterprise Edition Storage Overview

4.4

Object storage

Data is stored as objects and a technology that creates more abstraction, often on top of and across local file

systems. Instead of blocks or files, data in the system is managed as objects across a global namespace,

with unique metadata for each object. This namespace can span hundreds of servers, enabling easier scaling

of capacity than either SAN or NAS models.

4.5

Software-defined storage

SDS is a flexible storage model that separates storage functionality from the hardware, where storage

becomes one of the services. Hardware independence architecture enables services and data to flow more

freely when applications change, and systems scale up and down. Data protection and data recovery can

then be implemented as another service limiting silos of functionality in a large business.

Self-service clouds that operate at application and infrastructure layers are multibillion dollar businesses.
