Hi Mohamed,
thank you for your reply.
I thougt, there is a SAS-Expander on the backplanes of the SC847, so all
drives can be run. Am i wrong?
thanks,
Markus

Hi Markus,
X10DRH-CT can support only 16 drive as default. If you want to connect
more drive,there is a special SKU for more drive support from super
micro or you need additional SAS controller. We are using 2630 V3( 8
core - 2.4GHz) *2 for 30 drives on SM X10DRI-T. It is working
perfectly on replication based cluster. If you are planning to use
erasure coding, you have to think about higher spec.
Does any one know about the exact processor requirement of 30 drives
node for erasure coding? . I can't find suitable hardware
recommendation for erasure coding.
Cheers

Hi,
i have a backup-storage with ceph 0,93
As every backup-system it is only been written and hopefully never
read.
The hardware is 3 Supermicro SC847-cases with 30 SATA-HDDS each
(2- and 4-TB-WD-disks) = 250TB
I have realized, that the motherboards and CPUs are totally
undersized, so i want to install new boards.
I'm thinking of the following:
3 Supermicro X10DRH-CT or X10DRC-T4+ with 128GB memory each.
What do you think about these boards? Will they fit into the SC847?
They have SAS and 10G-Base-T onboard, so no extra controller seems
to be necessary.
What Xeon-v3 should i take, how many cores?
Does anyone know if M.2-SSDs are supported in their pci-e-slots?
Thank you very much,
Markus
