Here you have total 8 ports in the iscsi storage side, and you need to have 8 pnics and 8 vmkernel ports in the esx side, then only you will get the full bandwidth. that is there should be an end to end mapping, that is one esxi vmkernek ip to ine storage target ip.
else you need to use etherchannel or LAG
I strongly disagree with this one. This will be true only if:
there is a single host accessing array
there are at least 8 luns on array, all accessed at full throttle at the same time, every LUN via different NIC (one active path per LUN at a time, unless you're using 3rd party multipathing plugin)
You will be able to access iSCSI array even if you have just a single RJ45 port on your host. Typically people use 2 for availability.
