vSAN – TCP Inbound Lose Rate

This post was originally published on this site

Hi guys,


does anybody know or have the same behavior about the “TCP Inbound Loss rate”.

We use vSAN 6.7U3 and got a small loss rate of 0.1% to 0.2% on all hosts.



Take a look to the screenshot below. It’s from the performance view (host network – time range 24 hours) of two vSAN hosts.

It’s interessing that we see this small loss rate most time outside of our business hours.

This is a VDI environment and so there is no really load on the servers before 6 am or at weekend.


We don’t have any vSAN Host packet discards or drop rate. Only get this small loss rate. I also don’t know if this have any impact to our environment.


Maybe anyone can clarify?
