Dynamic Cache Partitioning: 

Allows the ALLOCATION of PORTIONS of cache to specific device groups.

Symmetrix Priority Controls: 

Allows the prioritization of read I/O and SRDF/S transfers by host applications. 

Symmetrix Optimizer: 

Optimizes performance by MONITORING access patterns on storage arrays and transparently moving data between storage tiers. 

Virtual LUN: 

Allows the movement of data between storage tiers. 

Fully Automated Storage Tiering (FAST): 

provides sophisticated background algorithms that can automate the allocation and relocation of data across storage tiers based on the changing performance of applications. 

Storage provisioning with symaccess allows you to create a group of devices, a group of director PORTS, a group of host initiators, and with one command, associate them in what is called a masking view. Once a masking view exists, devices, ports, and initiators can be easily ADDED or removed from their respective groups.
