Dell Server Hardware Advice

Hello Everyone -

We currently have a 4-node cluster running on Del R820s, each with 4 x E5-4650 2.7Ghz CPU, 256GB RAM, 10GB NICs, and mirrored SSD drives for VM/CT and NFS for other storage. We run Cisco Nexus 10G switching as our backend corosync separately from our 10G frontend.

These servers were purchased used about three years ago and have done a great job for us, but we are starting to load them down, and I want to start augmenting them (for eventual replacement) with some more powerful Dell (preferably 1U) servers. Right now, I would like to purchase 2 x 1U servers to replace one of my R820s. Same overall footprint in the rack but a lot more capability.

Unfortunately, there are many Dell servers out there that range from inexpensive to over-the-top expensive and everyone selling them wants me to buy the biggest and best.

I was hoping someone here has experience with Dell servers (specifically) and what would be a more powerful option in 1U than my current R820s that run Proxmox without any issues.

I appreciate any guidance and wisdom.
If buying used, I prefer 13th-gen Dells, specifically the R730xd in which you can use the rear drives as RAID-1 OS boot drives.

If looking for something else newer, then 14th-gen Dells, like the R740xd.

I would not get 15th-gen Dells until the Linux drivers for that hardware has matured.
