I don’t have db VM, I think you are referring to deb which is short for Debian.

GID VMNAME NVDISK CMDS/s READS/s WRITES/s MBREAD/s MBWRTN/s LAT/rd LAT/wr

12953 dns - 1 0.00 0.00 0.00 0.00 0.00 0.000 0.000

16904 fw - 2 5.84 0.00 5.84 0.00 0.02 0.000 18.408

130847 - 2 0.00 0.00 0.00 0.00 0.00 0.000 0.000

626694 deb - 2 12.06 0.00 12.06 0.00 0.46 0.000 6.586

as you can see the is no much IOPS per VM, like vcsa VM latency I captured is floating between 20 and 100ms, while deb has similar IOPS but lower latency

That is the thing, my total IOPS are less than 150, with 4 disks in RAID 10 I believe I should get 300IOPS due to mirroring. If you look at the graph, red line is transfer in kbps and blue latency, why is it dropping when disk is highly utilised? I will post htop when I’m back from work.

30W should be enough, I have AP and couple of cameras, each consuming not more that few watts

I’m not sure if Ubiquity provides this level of telemetry, is there a reason why would you need to run it few time a day? In any case, you can always run WinMTR from your host.

Are your firewalls virtual/ hardware? What traffic goes where, what is site b, where is it? Where is proxy? Draw a diagram.

ILo updates were usually distributed in .bin files but that was in newer versions. Check vendor support site, it may be OS dependent https://support.hpe.com/connect/s/product?language=en_US&cep=on&kmpmoid=3984625&tab=driversAndSoftware
