Thanks Mark.
what cpu frequency/number of core do you use ?
I think these are dual E5-2607s.
For the system disk, do you use some kind of internal flash memory
disk ?
We probably should have, but ended up with I think just a 500GB
7200rpm disk, whatever was cheapest. :)
Pretty excited to see how well these do!
Mark

Thanks Robert !
I didn't that supermicro have 2utwin with 2x12disk, seem really
interesting !

Objet: RE: [ceph-users] servers advise (dell r515 or supermicro ....)
I would like to have this kind of configuration for each node:
- 2U
- 2,5inch drives
os : 2 disk sas drive
journal : 2 x ssd intel dc s3700 100GB
osd : 10 or 12 x sas Seagate Savvio 10K.6 900GB
Another option could be to use supermicro server,
they have some 2U - 16 disks chassis + one or two lsi jbod controller.
But, I have had in past really bad experience with supermicro
motherboard.
(Mainly firmware bug, ipmi card bug,.....)
Does someone have experience with supermicro, and give me advise
for a good motherboard model?
We are using Supermicro 2uTwin nodes.
These have 2 nodes in 2u with each 12 disks.
We use X9DRT-HF+ mainboards, 2x Intel DC S3500 SSD and 10x 2.5" 1TB
7.2k HDD Seagate Constellation.2
They have SAS2008 controllers on board which can be flashed to be a
JBOD controller.
For ceph we install the OS on the SSDs
Each SSD also gets 5 journals.
We have been using these machine for over a year now for various
purposes (including, a somewhat similar workload: Openstack Swift)
and are happy up to now.
You might want to look at the new recently announced 2uTwin pro
nodes if you want to have 10Gb copper on board.
The above machines just have 2x 1Gb.
I think all brands have their own quirks, the question is which one
you are the most comfortable to live with.
(e.g. we have no support contracts with Supermicro and just have
parts on stock)
Cheers,
Robert van Leeuwen
