Here, Open-E's iSCSI Enterprise clearly provides the better results. Average access times of 8.1 ms versus 10.2 ms make quite a difference. At this point, you may wonder how such a quick access time is possible, as the 7,200 RPM drives that we are using perform in the area of 12-14 ms. It is the iSCSI solutions' cache algorithms that allow for shortening access times here. While this can sometimes be an advantage, it certainly does not reflect the real average access time of the iSCSI target.
These results basically reflect the maximum bandwidth between the iSCSI target and our initiator system. As you can see, the bandwidth hits the limits of Gigabit Ethernet with Open-E iSCSI Enterprise (125 MB/s).
