iscsi - What determines the lag?

I am thinking of setting up an iScsi target to increase the hard drive space on one of my Windows VPS and just wondering what measure I should use to see if I would have lagging issues later on, is it the ping between 2 VPS (target and the client) that matters or some other measure that I could use to find out.

I used to set up one with an AdvantageCom VPS as the target and an KiloServe VPS as the client, although both were on the west coast, I had so much lag that I basically could not run any program installed on the target from the client....

  • iscsi is for the LAN, not for hundreds or thousands of kilometers.

  • It does work, I mounted a target in Romania from Italy and also made a few backups, but running programs... That's a negative to quote a classic still alive. M

  • iSCSI is over TCP which means it is limited by the speed of a single TCP connection. Which is limited by the RTT * tcp window. My guess is that NFS over UDP would work better in your case. No idea if it can be done with windows though, i am not a windows guy.

    There is a native NFS for Windows from Microsoft for a few years now, it is painful, frequent disconnects, slow performance, about what you'd expect from Microsoft.

  • Lame :) But what would you expect from Microsoft :)

    @zhuanyi tried regular windows share / network drive connect / samba / whatever it is called?

    So what would be the recommended way to get a network drive set up on a remote Linux VPS?

    Samba is good but for some reason some of the Windows programs would not recognize Samba mount as a local drive, which could be a pain as some programs are only allowed to be installed on a local drive.

  • @zhuanyi try samba if the client is windows.

    Ya, except that Samba mount won't be recognized as a local drive by Windows :(

  • Mount CIFS on a local (LAN) VPS/server, then export it as something else. M
