WinSrv 2008 R2 and Intel Pro/1000 GT quad-port nic, slow iscsi format.

We have two (2) Windows 2008 R2 Servers with the Intel Pro/1000 GT Quad Port server adapter. They are both connected to a SAN through iScsi connections, but when we format a 600gb drive on the lun, we get around 6-10 IO/sec. Total format time of the 600gb is around 7-8 minutes.

We have forced the 2008 Intel drivers to control the cards, as well as the "in box" Microsoft drivers for the cards, without any luck. All the drivers we have tested resulted in the same numbers for formatting.

On a side note, we hooked up a Windows 2008 Server to the same lun and formatted the 600gb partition in a matter of seconds, with the intel drivers installed.

Anyone else seen this with their cards, and have a fix ?

Thanks
