We have a pre-prod Ceph cluster and working towards a production cluster deployment. I have the following queries and request all your expert tips,
1. Network architecture - We are looking for a private and public network, plan is to have L2 at both the networks. I understand that Object / S3 needs L3 for tenants / users to access outside the network / overlay. What would be your recommendations to avoid any network related latencies, like should we have a tiered network ? We are intending to go with the standard Spine leaf model, with dedicated TOR for Storage and dedicated leafs for Clients/ Hypervisors / Compute nodes.
2. Node Design - We are planning to host nodes with mixed set of drives like NVMe, SSD and NL-SAS all in one node in a specific ratio. This is only to avoid any choking of CPU due to the high performance nodes. Please suggest your opinion.
3, S3 Traffic - What is the secured way to provide object storage in a multi tenant environment since LB/ RGW-HA'd, is going to be in an underlay that cant be exposed to clients/ users in the tenant network. Is there a way to add an external IP as VIP to LB/RGW that could be commonly used by all tenants ?
Thanks in advance.
