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,
Luca Passioni
