Dears,
now I have been toying around on a 32 GB RAM / i3 Box but apparently that didn't do the trick well enough so here is what I have now:
FreeNAS 9.10 Stable
X9SRH-7TF w. 6 C/ 12T CPU
64 GB ECC RAM
Volume 1:
5x 4 TB HGST 7k RPM Drives - RaidZ1, iSCSI, Plex, CIFS
1x Intel SSD DC S3710 200 GB as Log drive
2x Crucial 256 GB SSDs as Read Cache
Volume 2:
2x 3 TB WD NAS Red Drives - Mirror, iSCSI only
What I do: iSCSI, CIFS and plex (currently, planning to move CIFS / Plex to another box)
Mostly ofcourse I'm interested if the RAM should be enough for this build or not. Could probably add another 64 GB to it if really necessary.
I had on the 32 GB box random iSCSI Connection droppings so VMs running on this Hardware just froze away. Currently it's still only 1 VM on the whole pool as that freezing was what held me off from deploying more to it. CIFS also dropped after like 26 GB of Data transfered to 0 Bytes and never recovered unless I removed the Network cable from one of the i350-T4 Ports fast enough (as in I was waiting for the transfer to complete) then it sometimes continued with the data transfer.
Before I would cry for a bug I'd like to hear the ok for this Hardware configuration. I'm not looking for best iSCSI Performance, just no more VM freezing otherwise I'll have to rely on something else for my storage needs.
As I understand 16 GB RAM is minimum for iSCSI on FreeNAS, 26 TB worth of disks is if 1 GB / TB would be taken as target, fine and on 2GB / TB it would be just not enough by a tiny stretch. I enabled lz4 compression, no de-dup.
