Hi Brad,
that post was mine. I knew it quite well.
That Post was about confirm the fact that minimum requirements written
in the documentation really didn't exists.
However I never asked if there is somewhere a place where is possible to
download the DEV or the RC of Centos7.5.
I was thinking about to join the community of tester and developers that
are already testing Ceph on that "/not ready/" environment.
In that POST these questions were not really made, so no answer where given.
I see that you talked also about other distribution. Well, I read around
that Suse already implement iSCSI.
However as far as I know (which is not so much), this distribution use
modified kernel in order to let this work.
And in order to use it it's needed a dashboard that can handle these
kind of differences (OpenAttic).
I knew already OpenAttic is contributing in developing the next
generation of the Ceph Dashboard (and this sound damn good!).
However this also means to me that the *official dashboard* should not
be talking about ISCSI at all (as every implementation of iSCSI are
running on mod version).
So these are the things I cannot figure out:
Why is the iSCSI board on the CEPH official dashboard? (I could
understand on OpenAttic which run on SUSE but not on the official one).
And why, in the official documentation, the minimu requirements to let
iSCSI work, is to install CentOS7.5? Which doesn't exist? Is there a RC
candidate which I can start to use?
And... if SUSE or even other distribution works already with iSCSI...
why the documentation just doesn't reccomend these ones instead of RHEL
or CENTOS?
There is something confused about what the documentation minimal
requirements, the dashboard suggest to be able to do, and what i read
around about modded Ceph for other linux distributions.
I create a new post to clarify all these points.
Thanks for your answer! :)

See the thread in this very ML titled "Ceph iSCSI is a prank?", last
update thirteen days ago.
If your questions are not answered by that thread let us know.
Please also remember that CentOS is not the only platform that ceph
runs on by a long shot and that not all distros lag as much as it (not
a criticism, just a fact. The reasons for lagging are valid and well
documented and should be accepted by those who choose to use them). if
you want the bleeding edge then rhel/centos should not be your
platform of choice.

Thanks Jason,
this is exactly what i read around and I supposed.
The RHEL 7.5 is not yet released (neither is Kernel 4.16)
So my dubt are 2:
*1) If it's not released... why is this in the documentation?*
Is the documentation talking about a Dev candidate already
accessible somewhere?
2) why in the dashboard is there already a iSCSI board?
I guess I miss something.... or is really just for future
implementation and not usable yet?
And if it is usable... where I can download the necessarie in
order to start?

RHEL 7.5 has not been released yet, but it should be released very
soon. After it's released, it usually takes the CentOS team a little
time to put together their matching release. I also suspect that Linux
kernel 4.16 is going to be released in the next week or so as well.

iSCSI Targets
Traditionally, block-level access to a Ceph storage cluster has been limited
to QEMU and librbd, which is a key enabler for adoption within OpenStack
environments. Starting with the Ceph Luminous release, block-level access is
expanding to offer standard iSCSI support allowing wider platform usage, and
potentially opening new use cases.
RHEL/CentOS 7.5; Linux kernel v4.16 or newer; or the Ceph iSCSI client test
kernel
A working Ceph Storage cluster, deployed with ceph-ansible or using the
command-line interface
iSCSI gateways nodes, which can either be colocated with OSD nodes or on
dedicated nodes
Separate network subnets for iSCSI front-end traffic and Ceph back-end
traffic
