Any word of SAS-4 support from Broadcomm? I have a Adaptec (Microsemi) HBA 1200 (PCIe 4 SAS-4(/NVMe/SATA)) and this page: https://storage.microsemi.com/en-us/support/sas/sas/aha-1200-8i/ references a "SmartPQI 64-bit Driver for FreeBSD 11, 12 & 13". Has anyone tested that driver? The hardware seems to work fine on Linux. One new feature (that I had not seen previously) is that the HBA itself presents a SES device internally (i.e. it can't be seen by on another initiator connected to the same expander). From the machine with the HBA 1200 installed I see: # sg_ses -af /dev/sg3 Adaptec Smart Adapter 0107 Primary enclosure logical identifier (hex): Internal Device [0,-1] Element type: Array device slot Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Controller Temperature Sensors [1,-1] Element type: Temperature sensor Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Temperature=35 C emc_1414_int:0:0:Inlet Ambient [1,0] Element type: Temperature sensor Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Temperature=29 C emc_1414_ext1:1:1:Chip ASIC [1,1] Element type: Temperature sensor Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Temperature=35 C emc_1414_ext2:2:2:Vendor define [1,2] Element type: Temperature sensor Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Temperature=30 C emc_1414_ext3:3:3:Vendor define [1,3] Element type: Temperature sensor Enclosure Status: Predicted failure=0, Disabled=0, Swap=0, status: OK Temperature=34 C So it has 4 different temperature sensors on the card! Those figures are with a fan attached to its heatsink. Without that fan (and with no other air blowing on that card), I have seen temperatures above 70C. So a fan is needed (as MicroSemi recommend).
