2-4.5 SSD cache
Because the capacity of controller memory cache is limited, SSD Cache allows fast SSD to be used to
extend the cache pool capacity of storage systems and store frequently accessed data. With increased
capacity of SSD Cache, more hot data can be stored in the SSD Cache so future requests for the data can
be served more efficiently and the read performance is considerably enhanced.
Note!
SSD Cache is a feature requiring a license. Enable the license at Infortrend official website > Product
Service > License Service by downloading the license and uploading it to both the source and the
target GS model via Central EonOne.
The following content includes the brief operation steps for SSD Cache feature. For more detailed
information about SSD Cache, please refer to SSD Cache Application note.
1. Once you have purchased and applied the SSD Cache license, go to Settings Storage SSD Cache.
