Problem deploy slow
-
hi, I have 3 servers with exsi and each of them has 3 wm ( fog 1 fog 2 fog 3 ) the fogs are connected to single switches with 16 non-management ports. It’s happening to me that after having deployed on a few PCs the deployment speed drops drastically like 800/900mbs, when it normally goes up to 22gbs (gigabit) now the question is: is there anything that needs to be done on the fog side? like cleaning something or other?

@alexamore90 Lets try to unpack this.
You have 3 ESXi servers connected to an unmanaged switch.
This part is a bit unclear. After deploying on a few pcs the speed dropps to 900mb/min (watch your unit of measure). Normally its up to 22GB/min (again assuming you are getting this number from partclone).
After deploying to a few PCs the speed drops. Is this simultaneous deployments or consecutive deployments the speed drops?
Unmanaged switch: So this isn’t an enterprise class switch. You may have issues with throughput on the switch itself. The aciscs might not be fast enough for the amount of data your are trying to push through. Look at the throughput listed in the technical documentation for the switch.
You didn’t mention the uplink speed from the ESXi servers to this switch. On a well managed 1GbE network you should get around 6GB/min throughput. On a well managed 10GbE network I’ve seen 13-15GB/min. So your 22GB/min seems a bit higher than expected. I can say with a physical FOG server connected via 1GbE link, I can saturate that 1GbE link with 3 concurrent image deployments. When that happens the error rate increases and the throughput drops off quote a bit.
The other thing if you are trying to do concurrent deployments with these 3 FOG servers, make sure the drives on ESXi are SSD or NVME drives and not spinning disks for performance reasons.
In the end I don’t think this is a FOG server issue specifically, rather something in the environment that is causing the speed issue.
