> >> I am thinking of designing a cephfs or S3 cluster, with a target to achieve a minimum of 50GB/s (write) bandwidth. For each node, I prefer 4U 36x 3.5" Supermicro server with 36x 12TB 7200K RPM HDDs, 2x Intel P4610 1.6TB NVMe SSD as DB/WAL, a single CPU socket with AMD 7302, and 256GB DDR4 memory. Each node comes with 2x 25Gb networking in mode 4 bonded. 8+3 EC will be used. > > You should look to 16TiB HDD's, 12TiB give's you 25% lower space for date on same physical dimensions (units, power) Why stop at 16TB instead of going to 20TB? And have 25% more capacity yet trying to squeeze through the same SATA bottleneck. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
