Please read the FAQ. This question (and what would happen to you disk with multiple access from concurrent machines) was mentioned there. Thanks!

this is the FAQ >??
Q. I share a hard drive with SPTI module. When I write a file onto the share drive I can't see or access it from the local server's account. If I write a file from the server's logged-in account I can't see it from the remote client.
A. Configurations where remote iSCSI clients and local server processes access the same drive are not supposed to work correctly with read/write devices, because the file system's data is not synchronized between clients. If you use such a configuration, the file system will be corrupted in short time.
There are 2 ways how to use shared iSCSI disks:
Using of a distributed (SAN) file system. (MetaSAN iSCSI or DataPlow SFS are supported)
Using of the MS Clustering Services.
NOTE: StarWind since v3.2.1 has SPTI access blocking local file system calls when a remote client connects (except the "Share RW" set).

YOU PHYSICALLY CANNOT DO WHAT YOU WANT
Neither with StarWind nor with any other iSCSI target.

Hi,
To mount a SPTI device from multiple hosts simultaneously, set the 'Number of sessions' parameter properly.
BUT using the same hard drive from multiple hosts in this way will definitely destroy the disks logical structure.
Have you tried using of cloned IBVolume targets to support your cafe machines?
This is a good way to go in your case.
