i've 2 server ML 350 G6 in cluster,and i have iSCSI storage.
should i use the iscsi connecion to the storage through the iSCSI softwar or iSCSI adapter from performance view? (i've 2 adapters like that)
Performance does not differ too much... IMHO I prefer have Jumbo Frames and use the software initiator.
