So, I just did my first actual step (beyond planning and theorizing) in building out a homelab.
I ordered a 7302P on eBay!
So, since it’s official, I have decided to document my journey.
First, a little bit on the hardware.
The background: this will be my everything server. NAS, virtualization, firewall, software builds, everything. I don’t plan on getting a second one in the foreseeable future.
I was looking at various solutions, T630, W680, AM4, all missed something. Be it PCIe slots, bifurcation, something was always missing.
Then a friend nudged me: there are EPYC 7302P chips from China on eBay for 270 USD. Damn. Everything I wanted and it doesn’t break the budget. Not to mention the great upgradeability (even if I can’t upgrade to Milan, I can still look for a 64c chip in the future, as compared to my 16c 7302P). I’m sold.
Then came three days of frantic research and and searching. The motherboard was settled fast - Supermicro H12-SSL. Although halfway through I decided to go from a used one from the same seller as the CPU to buying a new one - the price difference wasn’t enough to offset the lack of warranty.
RAM was easy to find - currently you can get 8x16 GB 2133 ECC RDIMMs for 200 euro.
What came next - case and cooling - were agony. I don’t trust a 92mm 4U cooler to be quiet enough for my needs. Nothing bigger fits in 4U. Do I even want it rack mountable? In the end this issue was settled by a friend offering me a free case. For the cooler I decided to go with Noctua because they guarantee compatibility with the motherboard. U9 TR4-SP3 to be precise, check if it isn’t too load, keep or replace with U14S.
As for PSU, I decided to move the HX850i from my PC - great PSU, high efficiency, lots of connectors, power monitoring - and get an RM850e for my PC.
Other than that - I’m going all flash. Six Kioxia Exceria G2 1 TB for data, and two TBD 250 GB NVMes for the OS. Altough I’m also trying to do some fishing on eBay for used enterprise SSD drives, but don’t expect good results.
TLDR for the specs so far:
- EPYC 7302P
- Supermicro H12-SSL-i
- 8x 16GB 2133 ECC RDIMM
- Corsair HX850i
- Dark Base 900
- 6x Kioxia Exceria G2 1TB for the data array (they’re dirt cheap over here)
- Asus Hyper M.2
Some of you might’ve noticed the lack of any sort of NIC - the network infra I have right now is, basically, nonexistent. ISP-provided everything-router and that’s about it. So I need to build the whole network because I can start thinking about NICs.
Next post will be about the software I’m looking to use.
