This seems to contradict your statement above.<br>
<br>
My 'assumptions' are these:<br>
<br>
* The system datastore needs to be shared. In order to have it appear on<br>
the hosts, I must manually export it on the frontend, mount it via nfs<br>
on the hosts. Symlinks are all that appear in the system datastore, and<br>
these point to block devices that have been attached to the hosts.<br></blockquote><div><br></div><div>Right</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
* Each host needs to attach to all iSCSI targets that are needed by<br>
guests running on the host. It's not entirely clear to me if ONE handles<br>
all that or not (assuming it does).<br></blockquote><div><br></div><div>ONE handles this by login/logout in an iSCSI session as needed</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
* a guest attaches to the symlink in the shared system datastore, but<br>
this link actually ends up pointing to a *local* iSCSI attached block<br>
device, so it does not become a 'bottleneck' to any IO traffic.<br></blockquote><div><br></div><div>Well, depending on the performance of your iSCSI server and networking, number of VMs, traffic generated...</div>
