My skills in english are fair but that’s all, that’s may be why my message was not clear enough.
To resume :
-We had a NAS LUN linked to the legacy FOG Server
-We rarely do unicast deploy, 95% are multicast.
-Running 3 or more multicasts start causing slowdowns on the WebUI.
-Sometimes we have up to 10 simultaneous multicasts. Very have rarely more, even
with 23 classrooms on the main site.
As the nic used to access the WebUI is the same as the one that flood the images through the network we thought that we could mitigate this phenomenon using storage node.
We are note stuck to a model or another, we are still searching for the best compromise.
Now we have/had a second issue it’s image export/Import. We plan to use replication at the end but for the first load which represent several TB sync through a wan link is not possible.
It seems this issue is now solved, the remaining “problem” is only cosmetic, but may be I did something wrong, it was the first time I moved images from storage to another and tried the export/import.
