I've been watching my drive temperatures in the Mini XL+ that I have in the office and the temperatures appear high compared to the workload. The configuration is pretty basic. The are three pools:
data0: 3 7200 RPM HDD RAIDZ1 + Log device (SSD)
data1: 3 SSD RAIDZ1
backup0: 1 5400 RPM HDD
The system is basically idle right (0% disk busy) and the HDDs are about 50 C. The ambient temperature in the room is 78 F. A second system (but not a Mini XL+) running TrueNAS with comparable drives (7200 RPM HDDs and SSDs) has temperatures below 40C and the Disk Busy is 2% - 5%.
Looking the forum, it appears that the Mini ran hot, but I have not seen any comments suggesting that the Mini XL+ ran hot. Bays 2-5 is the top quad and Bays 6-9 is the bottom quad. The options I'm considering:
1) Moving bay 3 to bay 4 and bay 7 to bay 3 to see if that helps.
2) Replacing the 7200s with 5400s
3) Replacing the 7200s with SSDs (lots of storage is not a requirement).
I went with the 7200s because of the speed advantage, so going to a 5400 is a bit of concern. The data0 pool has some iSCSI volumes and NFS shares and gets a decent amount of writes (hence the SSD log device), so going to a SSD is also a concern.
Any recommendations or suggestions on how I should proceed? Other than the temperatures, I've been happy with the Mini XL+
