hello if it's only for a poc you can try to rent devices for some month. for less that 100€ per month you can get this kind of device at ovh.com - 32go RAM - Intel Xeon-E 2274G - 4 c/8 t - 4 GHz/4.9 GHz - 3× 4 To HDD SATA Soft RAID or 2× 960 Go SSD NVMe Soft RAID - 2 x 2Gbps network Personnaly I use bunch of them for my kubernetes prod (the one with 2× 960 Go SSD NVMe) and it's working pretty well. You can tweak to get more or different disk setup, more ram, more network speed. Everything is here : https://www.ovh.com/fr/serveurs_dedies/infra/tarifs/ The device I'm talking about is INFRA-1 oau Le dimanche 08 mars 2020 à 19:00 -0700, Ignacio Ocampo a écrit :
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!
