hello I'm trying free nas on my forklift (workstation) with these hardware features
xeon 4 cores 3ghz
16 GB RAM ECC (if necessary I can bring them to 32)
1 X 120 Gb ssd (installed freenas poll boot)
3 X 4 TB WD red RAIDZ1 (data pool)
I activated the deduplication on zfs and for now I'm happy, I use NFS and copy my backups to about 60/70 Mb per second. NOT BAD!
Deduplication is not an option for me, I use it to save 10 days of vmdk images or kvm images of my Virtual machines.
Deduplication really makes me comfortable.
This setup at the moment ,have about 110 GB of SSD not partitioning and not used, this is a waste!
That said my goal would be to get about 100Ms or more in copy.
Adding the part of the 110Gb and setting it as zfs cache I would get some improvements? would it also help me if 16 GB of ram were not enough?
In the zfs cache, the data is only cached, so in case of a break, do not I have to worry about it?
my idea of write cache ssd would be that this quickly receives my backup and then simultaneously goes to the hdd more slowly, at the end of the copy I still have some writing until the cache is empty.
I still do not understand how these zfs caches work, sorry for that
