MSA2312fc Windows 2008 x64 write performance

This is my configuration.

N.1 Server HP DL380 G6 Windows 2003 SP2 x32
N.1 Server HP DL380 G6 Windows 2008 SP2 x64
N.1 MSA2312fc
N.2 Siwtch 8/20q
N.2 HBA 81q (two for each server)

N.1 Array RAID-10 and two LUN for each server.

Firmware and driver are updated.
Both server make boot from SAN and are diskless.

I have a write performance problem on Windows 2008 x64.
On Win2008, I test my DL360 G6 with a file copy from one LUN to a second LUN.
With performance monitor the write speed is about 30Mbit/s.

From the Windows 2003 x32, no problems are detected.
The server are identical, the only difference is os version.
With Win2003 performance test report me about 1Gbit/s for write and 1Gbit/s for read.


Can You help me where is the problem?
I think that could be a os problem (like MPIO), but i make a lot of test without results.


Best regards,
