I find they, emc volumes, lvm, Netapp, IBM Svc and Zadara Virtual
Private Storage
Array,  are all use ISCSI to be the bridge to make drivers to let
Openstack support
them. You can see their driver files here:
https://github.com/openstack/cinder/tree/master/cinder/volume/drivers

Therefore, it seems they are all not open source projects, which
belong to companies.
So i can not get their source codes and may not study ISCSI way well.
Morita, cloud
you please give me some suggestions?
