Hello All,
We have been using our netapp primarily for NAS storage, but I am experimenting with iSCSI now for some specific applications. I managed to create a bit of a network issue recently when I tried enabling jumbo packets on my netapp and my test server. The iSCSI connection kept resyncing and was not stable. I think this was because I didn't create a separate vlan for the devices using jumbo packets. Upon further research, I found mention that some devices/ oses calculate the checksums differently and that can affect the max packet size. Does anyone have any recommendations for a packet size for both the netapp and for my linux servers? is 10240 a safe bet(max size supported by my switch) or should I use something like 9000 or 8192? Should I use a different packet size if I am connecting a target to a windows box? I would ideally like to make a jumbo packets vlan and just set all the devices on that vlan to a larger MTU, but I don't want to create a network traffic problem in the process.
