HUS and its amount of available cache

Dear Community,

 

I'm looking for an explanation why my HUS150 only have 4.57GB cache per controller available.

The machine is supposed to have 32GB, means 16 per controller, means 8 mirrored per controller.

So I should see, theoretically 8GB per controller. But in Tuning Manager, I'm seeing only 4.57.

 

I know that services, like ShadowImage are taking piece of cache.

I've checked my machine and so that ALL Licenses are enabled:

 

CACHERESIDENCYEnabledPermanent
SNMP-AGENTEnabledPermanent
SHADOWIMAGEEnabledPermanent
LUN-MANAGEREnabledPermanent
SNAPSHOTEnabledPermanent
DATA-RETENTIONEnabledPermanent
PFM-MONITOREnabledPermanent
CACHEPARTITIONEnabledPermanent
AUDIT-LOGGINGEnabledPermanent
ACCOUNTEnabledPermanent
VOL-MIGRATIONEnabledPermanent
D_PROVISIONINGEnabledPermanent

 

We need only HDP Pools, CoW and ThinProvisioning.

Could I disabled some (and reboot the array) ? would it give me more cache available ?

Which of those licenses are costing me cache ? Which not ?

Which are safe to disable/remove ?

 

Thanks,

Anthony
