Hi Wido,
what are you trying to optimise? Space? Power? Are you tied to OCP?
A lot of things. I'm not tied to OCP, but OCP has a lot of advantages
over regular 19" servers and thus I'm investigating Ceph+OCP
- Less power loss due to only one AC->DC conversion (in rack)
- Distributed UPS by having UPS in each rack
- Machine maintenance without tools
And the list goes on. But I don't want to make this a OCP thread or
commercial.
Just wondering of there are people who have OCP servers running with
Ceph and if so, which models.

I remember Ciara had some interesting designs like this
http://www.ciaratech.com/product.php?id_prod=539&lang=en&id_cat1=1&id_cat2=67
though I don't believe they are OCP.
I also had a look and supermicro has a few that may fill your
requirements (https://www.supermicro.nl/products/system/1U/6019/SSG-6019P-ACR12L.cfm)

Hi Wido,
We have used a few racks of Wiwynn OCP servers in a Ceph cluster for a
couple of years.
The machines are dual Xeon [1] and use some of those 2U 30-disk "Knox"
enclosures.
Other than that, I have nothing particularly interesting to say about
these. Our data centre procurement team have also moved on with
standard racked equipment, so I suppose they also found these
uninteresting.
Cheers, Dan

Hi,
I'm looking at OCP [0] servers for Ceph and I'm not able to find yet what
I'm looking for.
First of all, the geek in me loves OCP and the design :-) Now I'm trying to
match it with Ceph.
Looking at wiwynn [1] they offer a few OCP servers:
- 3 nodes in 2U with a single 3.5" disk [2]
- 2U node with 30 disks and a Atom C2000 [3]
- 2U JDOD with 12G SAS [4]
For Ceph I would want:
- 1U node / 12x 3.5" / Fast CPU
- 1U node / 24x 2.5" / Fast CPU
They don't seem to exist yet when looking for OCP server.
Although 30 drives is fine, it would become a very large Ceph cluster when
building with something like that.
Has anybody build Ceph clusters yet using OCP hardaware? If so, which vendor
and what are your experiences?
Thanks!
Wido
