<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">I am reporting my experience with connexion speed between the so-called FEI server that records Falcon 3 frames (running under Windows) and an Ubuntu 16.04 workstation, connected with a
direct 10G glass fiber. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">As pointed out by several of you, using Samba instead of NFS is the way to go.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">However Samba is a bit of a jungle as three names are used to speak sometimes of the same thing, sometimes of different things. These names are Samba, SMB, and CIFS.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">It doesn’t really matter what they mean since not everyone agrees on common definitions. What matters is what you can practically do to get high transfer rates, both ways.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">1st solution, pointed out by several of you: share a linux folder with windows using samba. For that you might need to install Samba (warning: this is not the same as cifs-utils):<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">sudo apt-get install samba<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="DE" style="mso-fareast-language:EN-US">then edit /etc/samba/smb.conf and specify which folder to mount (getting everything right with respect to permissions was a bit of a pain but you’ll get there with google on your side).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Restart samba server:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">sudo service smbd restart<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">you should then see your linux drive in windows and transfers should be fast.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">2<sup>nd</sup> solution. After trying to figure out what the difference between CIFS, SMB, and Samba was I found an easier and cleaner way of setting up the connection. Here we mount
a windows share on the linux workstation using mount.cifs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">As previously pointed out, if you use the regular mount.cifs (or mount –t cifs) speed will be miserable.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">The trick is to specify the SMB version. To get fast connection with the FEI server you need to use at least SMB 2.1. On Ubuntu the latest SMB version available with mount is 3.0. By
default, mount uses SMB version 1.0. Note that smbd uses SMB version 3.0, hence it is working fast out of the box.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">With mout, you can specify SMB version with the optional keyword “vers”. You’ll find more infos about when and why to use which version in the man page of mount.cifs<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Here is an example mount command:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">sudo mount -t cifs -o username=feiserverusername,password=feiserverpassword,vers=3.0,uid=1004,gid=1004 //10.0.0.1/benshare testshare<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">This mounts the share benshare from the FEI server in the folder testshare on Ubuntu station; uid and gid ensure that user 1004 can read and write in this folder.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">This solution gave the best results in our hands. We reach 1 Gbyte/sec in both directions.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Hope this will be helpful to others (this could also be integrated in Falcon3 user’s manual)<o:p></o:p></span></p>

to the IP address, otherwise you cannot unmount the drive easily (a windows bug).<o:p></o:p></p>

to mount the Linux RAID as a volume on the K2 computer so we could just directly store frames there during acquisition. Similar to your experience we discovered that the performance of the NFS module in Windows is abysmal, even after tuning.

drive, which will generally max out in data I/O at 150-200 MB/s. Most machines used for storing high bandwidth data will either use a RAID 5/6 array of traditional hard drive (which can achieve 1000-2000 MB/s depending on the number of drives) or high speed
SSDs which will max out at ~600 MB/s on a standard SATA bus, but can achieve 1000-3000 MB/s if alternative interfaces are used.</span><o:p></o:p></p>

Strangely, file transfer from linux to windows is fast (600 MB/s) whereas file transfer from windows to linux is slow (160 MB/s). We have tried mounting the windows drive on linux through cifs or nfs, as well as mounting the linux drive on windows through
nfs and we always get the same result.</span><o:p></o:p></p>
