Hello, My company is plaining to build a big Ceph cluster for achieving and storing data. By requirements from customer - 70% of capacity is SATA, 30% SSD. First day data is storing in SSD storage, on next day moving SATA storage. By now we decide use a SuperMicro's SKU with 72 bays for HDD = 22 SSD + 50 SATA drives. Our racks can hold 10 this servers and 50 this racks in ceph cluster = 36000 OSD's, With 4tb SATA drives and replica = 2 and nerfull ratio = 0.8 we have 40 Petabyte of useful capacity. It's too big or normal use case for ceph? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
