10GbE Adapter Performance Evaluation

September 2010

Page 9 of 18

In most cases, the performance numbers were fairly close for all three adapters. In some cases, one

adapter performed better and in other cases a different adapter performed better.

The SQLIO output includes thread count (“T”) and queue depth (“Q”) for each data point.

One interesting result of most of these tests was that the performance of the single-path FCoE and

iSCSI connections to the NetApp storage yielded very similar results. The multi-path FCoE

configuration performed 10%-15% higher than the same iSCSI multi-path configuration.

FCoE vs. iSCSI

We used the Microsoft iSCSI software initiator on the host server for all the iSCSI testing for each

of the adapters.
