NVME-Based NAS, Which Processor to Choose?

Hardware Hub Build a PC
1

Hi Everyone,

I am looking at building a new homelab NAS to replace my aging “repurposed from work” HP DL Gen 5/6 fleet and am trying to decide on a processor.

I am planning on having 6-12 NVME (1-2 IceDock Backplanes) and 10 SATA Drives in the Sliger CX4713 case and so by default I’m thinking TRX50 motherboard + Threadripper pro to accommodate my PCIE lane needs.

The question though is do I need to stick with 7000 Pro series or can I go with 3000 or 5000 Pro series, get the PCIE lanes I need but avoid overkill processor capacity that I likely wont’ need for running Truenas.

Intended use for the NAS is shared storage (multiple 10G nics) for 3 XCP-NG loads (light usage, with some occasional lab testing) and a few TrueNAS docker apps.

Thoughts?

You don’t have to threadripper pro, just the normal ones would do.
You get 88 pcie lanes usable with those and 128 with the pro version.
If you’re buying everything new I’d suggest to go for the 7000 series. Or eventually with Epyc, as you get 128 lanes of pcie and have a higher number of options available regarding core count.
