Hi All.
Long term lurker here..
So iv been playing with Truenas for years. I've always shied away from making it home prod as I'm not great with Linux. But when the pandemic hit I decided to grab this opportunity and break this cycle..
Anyway, I currently use (For my sins) a Synology 1817+ (10Gb card, 6x12tb fronted with 2x1,9tb Intel SSDs (Cache)) the performance is not what you would call blow your socks off... 300Mb tops.
So I decided to repurpose one of my spare esxi nodes ( ASROCK D1541D4U with 64Gb RAM, LSI 9400-16i connected to 12x 960Gb SSDs in a 4vdev x 3 Disk rz1 Config (For testing)) I can now pin the network to 10gb easily and this is making the VMS feel much more snappy, especially the SQL Servers (DBA 9-5 job). esxi boxes connected via multipath nfs 4.1 to truenas.
Iv maxed out the RAM (64gb, technically I could do 128GB if I could find the DIMMs without having to sell body parts.) but was wondering if an optane m.2 in the nvme slots as a SLOG would help at all with so many SSD behind this pool. From research it seems the optane drives top out at 280mb but as i understand that this is only for random writes? I don't think using the nvme slots as an L2ARC would be useful.
Anyone got any useful info on this.. Most seem to be using a SLOG in front of HDDs and i can see the use for this just don't know if it will be anyuse with SSDs.
Also not 100% sure on the optain drive will work in this board.
Anyway Cheers
Rob
