Achieving high throughput with iSCSI on Virtual Machines (VMs) has proven to be difficult, as iSCSI protocol overhead is compounded by the cost of software IOV. Newer 10GbE NICs with hardware IOV support eliminate most of the software I/O virtualization overhead cost, allowing iSCSI software to run on VMs with better performance. Upcoming hypervisor support for SR IOV is facilitating a wider adoption of direct I/O from a Guest, allowing iSCSI software to achieve the performance typically seen in non-virtualized environments. Next generation of iSCSI hardware is likely to combine the best features (but not the current limitations) of hardware IOV NICs and iSCSI HBAs.
