Multiple Connections to a single ISCSI LUN?

I am wondering if I create a single large ISCSI LUN and a single corresponding ISCSI target to that LUN.  Stop me here of my understanding of this is incorrect.  Can I connect multiple servers to that same ISCSI target, so that they can all access that LUN (even simultaneously).  Or do I need to create a new target to the LUN for every server that I want to connect?

It depends very much on what you want to achieve.

Best practices would say that a new target is best practise but for Hyper V CSV purposes I use same ISCSI target.

You can connect several VMware ESXi Hosts to a single iSCSI LUN, or you can connect several Hyper-V Servers to a single iSCSI LUN using Cluster Shared Volumes (CSV) - but these are special cases for hosting Virtual Machines.

What do you want to do ?
Paul SolovyovskySenior IT AdvisorCommented:
To have multiple connection to a LUN without corrupting data you will need to have an operating system on the host side that can support this.  Whether this be Vmware ESXi, Hyper V, Micsrosoft clustering it will work.  If you want to connect a typical windows or linux server that is not configured for clustering it may work but you have a good likely hood of corrupting your data and possibility of resignaturing your  LUN causing total loss of data.

Damn, ok thanks for the info.  It looks like I will need to create some sort of platform agnostic clustered file system "share" and somehow map them to Windows Servers as if they were locally attached.

FYI I want to do this so that I can export/import hyper-v VMs to and from (I guess a) NFS share by adding it as "local" storage at the host level.  But I will make that a separate post.  This is because Hyper-v Manager seems completely incapable of exporting VMs to anything other than local drives.  I did get the ISCSI option to work, but of course I cannot attach another hyper-v host to it without fantastic badness occurring.
