Hi team, I'm planning to invest in hardware for a PoC and I would like your feedback before the purchase: The goal is to deploy a *16TB* storage cluster, with *3 replicas* thus *3 nodes*. System configuration: https://pcpartpicker.com/list/cfDpDx ($400 USD per node) Some notes about the configuration: - 4-core processor for 4 OSD daemons - 8GB RAM for the first 4TB of storage, that will increase to 16GB of RAM when 16TB of storage. - Motherboard: - 4 x SATA 6 Gb/s (one per each OSD disk) - 2 x PCI-E x1 Slots (1 will be used for an additional Gigabit Ethernet) - 1 x M.2 Slots for the host OS - Ram can increase up-to 32 GB, and another SATA 6b/s controller can be added on PCI-E x1 for growth up to *32TB* As noted, the plan is to deploy nodes with *4TB* and gradually add *12TB* as needed, memory also should be increased to *16GB* after *8TB* threshold. Edit Questions to validate before the purchase 1. Does the hardware components make sense for the *16TB* growth projection? 2. Is it easy to gradually add more capacity to each node (*4TB* each time per node)? Thanks for your support! -- Ignacio Ocampo
