Extreme Cache Pool - the Performance Booster

Extreme Cache Pool, the secondary cache built from dedicated drive enclosure based SSDs provides flash-drive class performance for significantly accelerated read access of servers and applications.

Using intelligent algorithms frequently accessed data is detected and automatically placed on fast SSDs – thus avoiding time consuming retrieval from spinning disk.

Extreme Cache Pool offers read performance and latency comparable to all-flash arrays while leveraging the cost advantages of conventional disk arrays. The feature can be activated separately for each volume, helping to achieve an even better cost/benefit ratio.
