Dear TrueNAS Community,
I've been a lurker on this forum for quite some time. However, now I would like to ask a question that I hope somebody can help me with.
For a new TrueNAS setup I would like to ask your help on how to setup a specific pool. One in which the SSD cache is used to keep the HDD's idle.
I am thinking of a pool with 3x 3T HDD and 2x 2T SSD cache (with some form of redundancy)
The use case is:
- Daily backup of photos (from phone). This backup is only sporadically accessed (once a month or less)
- 2 or 3 databases. Every minute some values are stored into these databases. Not much is logged, but the databases are quite 'large' (for me at least)
- About 500Gb of files I access regularly (multiple times a week)
- About 1 TB of files I access very sporadically (probably less than once a month)
I want to use the cache to access the HDD's less than 1 time a week and keep the HDD's in idle in the meantime.
To be clear; I do not wish to use the cache for faster read write. I want to use it to keep the HDD's in idle as long as possible.
Can anybody tell me how to setup a pool like described above? Where the SSD cache is used to keep the HDD's in idle for a long time. Is it even possible with TrueNAS?
Btw, I know the discussions about keeping the HDD's in idle and that the consensus is that you should not. But I guess that starting up a HDD approximately 52 time as year should not be any problem.
I thank you upfront for any help
Kind regards.
