Hi Markus,
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
