Fast Cache and Fast VP are part of the fast Suite. The two products can work together and complement each other when they are sold. FAST Cache enables the storage system to provide flash drive-level performance to the most frequently accessed block of data across the system. FAST Cache absorbs application surges in I/O, reducing the load on back-end hard disks. This can improve the performance of your storage solution.
This article will briefly introduce the difference between fast cache and fast VP.
Solution:
A comparison between fast VP and fast Cache function
Fast Cache and Fast VP sub-LUN tiering features can be used together to improve storage system performance and reduce its TCO. For example, with limited flash drives available, you can use flash drives to create fast Cache and use fast VP on both the performance pool and the capacity pool. From a performance perspective, fast Cache can provide performance benefits for any burst data dynamic, while fast VP can move more "hot" data to a performance drive and move colder data to a capacity drive. From a TCO perspective, fast Cache with a small number of flash drives is the most frequently accessed data service, while the fast VP can optimize disk utilization and efficiency.
