I have waited patiently for Scale to catch up with Core on Transfer Speed. Obviously the software isn’t anything unknown or magic. I have a HP DL380g8 and it only does 12MB/sec compared to a Core machine that does about 10 X faster. Could one of your coder’s incorporate the correct driver in the …

It’s unfortunate that you’ve run into an issue. Whatever the cause is - it doesn’t appear to be a wide-spread one so troubleshooting it would require more than the equivalent of “it doesn’t work”. Good luck with whatever you end up doing.

There’s nothing stopping you from remaining on Core. What is broken that’s eating all your speed? Network, LSI driver, what? They’re gonna ask the same stuff although if you file a bug report on that box running Scale, you can send a chunk of data that will include your hardware.

12 MB/s is ~ 100 Mbit/s, it seems to me something is negotiating at that speed. First thing I would check is the UTP cable and assuming it has a minimum of 4 pairs (8 wires) to check if it’s broken. Doesn’t seem like a TrueNAS problem imho.

We are still assuming we know what this “speed” is related to. Ethernet, or sata, or sas, or smb, it’s still a mystery.

Just go read some other posts by dhenzler under their account activity.

Since TrueNAS SCALE 25.10.1 doesn’t exist yet, I don’t see what the point of this thread is.

It isn’t hardware. The HP Servers I have are all same vintage and firmware is identical.
