Supermicro sells the Ablecom CS-M50 bundled with the FSP power supply (721TQ-250B).
The Chelsio SM10G-SR is the officially supported transceiver module for the SFP+ adapter.
According to iXsystems, there are temperature issues with drives over 6TB, and that is why they do not offer configurations with 8TB+ drives.
According to iXsystems, the FreeNAS Mini and Mini XL can be upgraded to 64GB of RAM, but due to the limited supply of 16GB UDIMMs, they do not offer that configuration. Here is some memory that should work fine. I’m having issues with a 64GB kit in FreeNAS 11. There was no issue with it in 9.10.
* It’s very likely that these model numbers change according to availability.
** Yes, iXsystems sells SSDs branded as L2ARC and ZIL, but really, they are both the same SSD.
Don’t get an ASRock C2750D4l or anything with an Intel Atom C2000 series chip in it. Something like a Supermicro A2SDi-8C+-HLN4F is a great alternative.
Hope this is helpful, especially for anyone in these two categories:
Even though this is already widely known, I thought I should post here to warn anyone not familiar with the issues around the ASRock C2750D4l and the Intel Atom C2000 series processors. I was vaguely aware that there were some issues, but now I am in the process of RMAing the board which is why I am posting this.
Here’s what is wrong with the ASRock C2750D4l.
In earlier firmware versions, the BMC wears itself out. The solution is simply to update it. If you have this board, be sure the BMC firmware version is at least 00.30.00. You can download the firmware here.
Both this board, and the Atom C2000 processors are flawed and will eventually have clock issues (the details of which are beyond my understanding), which will cause system instability followed by complete failure.
There are 2 redeeming factors here. First, all C2750D4l boards made after early 2017 Feb should be fine. The flaws are either fixed or worked around. Second, iXsystems extended the warranty for the board in affected FreeNAS Mini XL’s from 1 year to 3, so if you experiencing any mysterious hardware warnings or instability in your FreeNAS Mini, contact iXsystems and start an RMA.
