Depending on how things go with the Ceph iSCSI implementation goes I wonder if we can look at doing something more general where the volume node can act as an iSCSI gateway for any user that wants iSCSI support. I am not sure how hard creating a general solution would be or what the performance impact would be. It puts the volume node in the data path which may cause people to hesitate on this. Something to think about though.</div><div><br></div><div>Jay</div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Dec 5, 2018 at 5:30 PM Julia Kreger <<a href="mailto:juliaashleykreger@gmail.com">juliaashleykreger@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><br><div class="gmail_quote"><div dir="ltr">On Wed, Dec 5, 2018 at 2:02 PM Kimball (US), Conrad <<a href="mailto:conrad.kimball@boeing.com" target="_blank">conrad.kimball@boeing.com</a>> wrote:<br></div><div>[trim] </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="#0563C1" vlink="#954F72"><div class="m_7790598094183715732m_1102960100985513378WordSection1">
<p class="MsoNormal">One concern I do have is that it uses a proprietary protocol that in turn requires a proprietary “data client”. For VM hosting this data client can be installed in the compute node host OS, but seems like we wouldn’t be able to boot a
bare-metal instance from a ScaleIO-backed Cinder volume.</p></div></div></blockquote><div><br></div><div>Not supporting iSCSI would indeed be an issue for bare-metal instances.
