Hi everyone! I have to install a ceph cluster (6 nodes) with two "flavors" of disks, 3 servers with SSD and 3 servers with SATA. Y will purchase 24 disks servers (the ones with sata with NVE SSD for the SATA journal) Processors will be 2 x E5-2620v4 with HT, and ram will be 20GB for the OS, and 1.3GB of ram per storage TB. The servers will have 2 x 10Gb bonding for public network and 2 x 10Gb for cluster network. My doubts resides, ar want to ask the community about experiences and pains and gains of choosing between. Option 1 3 x servers just for SSD 3 x servers jsut for SATA Option 2 6 x servers with 12 SSD and 12 SATA each Regarding crushmap configuration and rules everything is clear to make sure that two pools (poolSSD and poolSATA) uses the right disks. But, what about performance, maintenance, architecture scalability, etc ? thank you very much ! -- Alejandrito _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
