Dell EMC Unity provides customers with affordable all-flash performance solutions or cost-effective hybrid solutions by using a midrange system that is optimized for simplicity across the storage lifecyclethat is, simple to acquire, deploy, manage, and service. The Unity storage system is ideally suited for midsized deployments, Remote Office/Branch Office (ROBO) locations, and cost-sensitive, mixed-workload environments. Unity storage is designed for all-flash arrays and is available for converged deployment, as a hybrid system, and as a software-defined virtual edition.

The Unity platform is offered in two different series of models, the x00(F) and the x50F. The x00(F) series includes the Unity 300 model and scales up to the Unity 600 model. 

Customers can order and configure Unity as either an all-flash or a hybrid system. The Unity all-flash models (300F to 600F) and hybrid models (300 to 600) are identical in form factor and connectivity, but scale correspondingly in processing and memory capabilities. The Unity All Flash series now includes four new models that are optimized for all-flash performance: the x50F models, starting with the 350F and scaling to the 650F. All new models feature additional processor cores and more system memory. The system limits change depending on the Unity model. 

Unity uses the latest technology in multicore processors, providing greater performance capabilities. Dell EMC recommends maximizing the use of flash drives in all Unity systems to optimize their performance potential.  

Note: Unity hybrid configurations support a maximum of 50 percent total flash capacity. If you require more than 50 percent flash capacity, consider a Unity all-flash configuration.
