Hi,

I have a HP Proliant DL360P G8 which commercial features are:

But according this screen, it seems that there is no cache:


How would you interpret this ?

Best regards,

Is this maybe an extra SSD cache which you could use?

• The HPE Smart Cache licensed feature (Available as an additional option) is a controller-basedread caching solution in a DAS environment that caches the most frequently accessed data(Hot Data) onto lower latency SSDs to dynamically accelerate application workloads

According to the product page at HP.

Some HP controller memory modules are removable, so your cache module (basically a RAM for the controller) is probably missing.
