Hello Nab, thank you for the elaboration. I was not aware of that issue. > It's still unclear (to me at least) at what number of LUNs per session > this becomes a problem for ESX, but I usually recommend users keep it in > the half dozen range (or less) per individual TargetName > +TargetPortalGroupTag endpoint. I go one step further and use one LUN per TPG. The reason for this is that I read long time ago in the UserGuide that each TPG is bound to one CPU on the target. Is that also still the case? By using one LUN per TPG I spread the load equally over all available Hyper Threads. At least this was my intention.
