Dear Cephers, 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.
My questions are the following: 1 How many nodes should be deployed in order to achieve a minimum of 50GB/s, if possible, with the above hardware setting? 2 How many Cephfs MDS are required? (suppose 1MB request size), and how many clients are needed for reach a total of 50GB/s? 3 From the perspective of getting the maximum bandwidth, which one should i choose, CephFS or Ceph S3? Any comments, suggestions, or improvement tips are warmly welcome best regards, Samuel [email protected] _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
