Yes, this is true. But it is better to consider all the possibilities.
For example, if we suppose a scenario where scaling to a redundant storage 
subsystem is very very expansive for a small business we may suppose a first 
phase where we have single controller/switch/hba per host etc. and a cheap 
backup low-prioirty iSCSI path.
In a second phase we can upgrade the hw and buy the second 
hba/controller/switch and so on.
Apparently it may be proper the hw-handler is on the iscsi server machine 
and the problem is solved, but i do not know if in the future, different 
scenarios may change this assumption.
