EMC FAST Cache technology gives a performance enhancement to the VNX Storage Array by adding FLASH drives as a Secondary Cache, working hand-in-hand with DRAM Cache and enhancing overall Storage Array performance. ... FAST Cache works with traditional Flare LUNs and VP Pools.
What is the difference between FAST Cache and FAST VP?
| FAST CACHE FAST VP | Data that is accessed frequently is copied from HDDs to Flash drives Data is moved between different storage tiers based on statistics collected over a period of time |

What is fast in EMC?
Dell EMC FASTTM software allows the Dell EMC UnityTM product family to leverage high-performance Flash drives . FAST software consists of Fully Automated Storage Tiering for Virtual Pools (FAST VP) and FAST Cache. These two features work in tandem to use the storage within the system as efficiently as possible.
WHAT IS FAST VP?
FAST VP stands for Fully Automated Storage Tiering for Virtual Pools . It’s a very smart solution for dynamically matching storage requirements with changes in the frequency of data access.
What is fast cache?
The FAST Cache is a large capacity secondary cache that uses SAS Flash drives to improve system performance by extending the storage system’s existing caching capacity. ... This allows a large set of slower, less expensive drives to deliver the performance typically provided by faster, more expensive drives.
WHAT IS FAST VP in unity?
FAST VP accelerates the performance of a specific storage pool by automatically moving data within that pool to the appropriate drive technology , based on data access patterns. FAST VP is only applicable to hybrid pools within a Dell EMC Unity hybrid system.
Does the storage pool support FAST VP?
Storage pools are the framework that allows FAST VP to take full advantage of different drive types . A pool is somewhat analogous to a RAID group, which is a physical collection of drives on which logical units (LUNs) are created.
