Hi Anthony, What is recommended number of servers for 2 datahalls for quality cluster? replicated pools x 4 will not work here?

This setup will work, but you can't use a reasonable EC profile for your bucket pool. Aim higher than the party line wrt PG counts esp. for the index pool.

To provide you with a bit of context, we have deployed hardware across two data halls in our data center, and they are connected via a 10Gb interconnect. The hardware configuration for 4 x Ceph Cluster (2 x servers in both data halls) * 2 x AMD EPYC 7513 - 32 Cores / 64 Threads * 512GB RAM * 2 x 960 GB (OS DISKS) * 8x Micron 7450 PRO 7680GB NVMe - PCIe Gen4 * Intel X550-T2 - 10GbE Dual-Port RJ45 Server Adaptor Our primary usage is Object Gateway and will be running 4 x RGW Service. We are aiming to deploy using cephadm and utilize all nodes for MON/MGR/RGW and OSD's Given our limited experience with Ceph, we are reaching out to the knowledgeable members of this community for recommendations and best practices. We would greatly appreciate any insights or advice you can share regarding the following aspects: Cluster Topology: Considering our hardware setup with two data halls connected via a 10Gb interconnect, what would be the recommended cluster topology for optimal performance and fault tolerance? Best Practices for Deployment: Are there any recommended best practices for deploying Ceph in a similar environment? Any challenges we should be aware of?
