Is my memory sufficient?

[haagen]

Hello,
I've got 24 TB of storage (6x 4TB) with few jails running on my FreeNAS.
Do you think I should buy another 2 RAM modules ?

See the screenshot.


Thank you very much!

That looks perfectly normal/OK to me... why are you concerned/asking? Is there a performance problem?

Thank you for your answer, sretalla!

There is not any problem at the moment, but from what I've I "should" have 8 GB of RAM for FreeNAS itself and as a rule of thumb 1 GB of RAM per TB of storage. In the future, I will have a few more Jails, or maybe even VM running - that's why those values concern me, as it seems to me that it is one the "edge"

maybe even VM running

Depending on the RAM allocated to VMs, you may want to reconsider how much RAM you have installed. At very least, you may want to limit the ARC size to allow enough room for the VMs.
