The new version of SDP that should be available soon will allow 32 bit applications to run on 64 bit systems as well.

Hi Tzachi, I was considering an FTP Server at first, but it is not the right tool for the job. The Situation is the following. It is a multimedia/video editing company. They need to access raw HDTV material from their windows workstations for editing and playback. So FTP is not an option in this case because FTP requires a full download to local memory. SMB/CIFS, NFS and maybe similar protocols seem to be the only options for real time playback and editing. Today I have tried tweaking the Windows XP TCP/IP settings by setting the Tcp1323Opts option and raising the TcpWindowSize to 512k. There was a little bandwidth increase but still not enough. If I am not mistaken using IPoIB on windows will not bring me near my performance expectations(300MB/s) at the moment. I will start trying the NFS(nfsaxe) over the SDP provider from Mellanox today. My biggest concern at the moment is that the Server is a 64bit Windows XP and the nfsaxe server application is a 32bit executable. If I read and understood the SDP Documentation correctly you can not use a 32bit application with SDP on a 64bit Windows?
thank you
