Keeping the LSI in the CPU slot and adding a RES2SV240 allows having 16 disks with around 140MB/s max

 

Adding another LSI to the x4 DMI slot, would limit those 8 disks to around 190MB/s, assuming they have all the DMI interface for themselves, if you are also using the onboard SATA for example, it will be shared by all and the speed would be considerably slower.

As my mother board was broken, moving to new system on i3 14100 

B760 that has x4 sata. Pcie4 x16, x4, x1 and 2 m2 x4. 

So I have 9207-8i for PCIe4 x16 port and ordered another 9207-8i for pcie4 x4 port. Or better way was to buy m2 to sata x6 that will use cpu or pch, that I wrote in recommended controller thread?

It depends on how many disks, the second 9207-8i will also use the DMI.

Some update on LSI HBA cards - power consumptions, IOPS, bandwidth etc - taken from Art of Server YT channel:

 

 

For in depth details see the Art of Server  YouTube channel.

I'll link the original videos.

Part 1 (8 SAS lanes) :

Part 2 (16 SAS lanes) :

 Methodology and Test bench : 

 

Seems to me based on this thread that 10 HDD (2xvdevs) will work faster and with less power consumption on 2 x Asmedia ASM1116 than my actual HBA LSI 9201-16i - (not taking in consideration the reliability of HBA cards ) 

If you're picking a card to use with existing drives, something to keep in mind is also that the 9300 and newer no longer supports SATA 1 (1.5gbit) drives, and SAS 4 (so the 9600 and newer) no longer supports SATA 2 (3gbit) drives. The 9600 also has to work a lot harder, so it uses about 17 watt for the 16i.

I haven't watched the videos, so I don't know if they measured temperatures but if not, most of the cards I have can get up to 60-65 celsius during startup, but usually they keep at 50-60 celsius during use. Exceptions are the 9211-8i, 9400-16i and 9500-16i which stay at about 40-45 celsius at most. This is all in a server with airflow, but all measured in the same condition (same slot etc).

So keeping in mind power, heat and functionality, at this time the 9400-16i wins.

Is anyway we can check hba controller temperature in Unraid ?

Have 2x 9207-8i

You need storcli and hba that provides temp.
