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.
Yes, I see. I was looking for a solution without a JBOD and about 12
drives 3.5" or ~20 2.5" in 1U with a decent CPU to run OSDs on.
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.
It really depends. When properly deployed OCP can seriously lower power
costs for numerous reasons and thus lower the TCO of a Ceph cluster.
But I dislike the machines with a lot of disks for Ceph, I prefer
smaller machines.
Hopefully somebody knows a vendor who makes such OCP machines.
Wido
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
