Controller features
HPE SmartCache
SmartCache is an advanced feature that enables solid state drives to be used as caching devices (for
reads and writes) for bulk storage. Data can be accessed and written to and from the solid state drive
instead of bulk storage. SmartCache provides the following features:
•
Accelerates application performance
•
Provides lower latency for transactions in applications
•
Supports all operating systems, without the need for changes
Use the HPE SSA utility to configure support for SmartCache.
This feature requires a license key.
