The ability of iSCSI to support high throughput depends on:

1Gbps ethernet can handle up to 115MB/s per interface. Using MPIO round-robin over several interfaces you can continue to add throughput if the application can scale well across these multiple paths.
I'm a little fuzzy on this Mb vs MB issue - which one is megaBITS and which is megaBYTES, and is this a standard convention or ???
Thanks.
20 years ago, Megabit was 2^20 bits (Mb) and Megabyte was 2^20 bytes (MB). The SI (ISO?) redid the units later to deal with the fact that Mega has a scientific definition of 10^6. This also allows the Hard-drive conspiracy to undersell you the number of bits on a disk. Nowadays, Mb is supposed to mean 10^6 bits, and a Mibit means 2^20 bits.
Thus you end up with a gigabit card which is 10^6 bits but the OS measures in 2^20 bits.
