I think this is not correct. We can easily do more than this on a single 1GB iSCSI connection. Theoretical top transfer speed of a 1GB connection is around 125MB/sec, and with iSCSI overhead we see around 110-115MB/sec per connection. All of our systems have at least dual iscsi connections and each can run more than 200MB/sec. Now, we do use Qlogic iSCSI HBA's, modern, low-latency gigabit switches, and jumbo frames, but we've seen over 95-100MB/sec even with software iSCSI with normal frames on reasonably modern hardware.
