+# I got tired of managing systems
+
+After messing with GlusterFS for a while, learning it's ups and downs, I've
+determined that I'm moving back to a single physical node, for the most part. I
+had a few goals in mind when looking at hardware.
+
+- Enough CPU/RAM to replace everything I currently run
+- PCIE expansion. Lots of lanes for everything I ram in there.
+- IPMI! I don't want to have to go plugging in display/keyboard constantly.
+
+This pretty much left me with 2 major system types to look at. Multi socket
+Intel Xeon's, or AMD Epyc systems. With old Xeon systems being even more work
+due to the absolute requirement of understanding [UMA and
+NUMA](https://www.geeksforgeeks.org/difference-between-uniform-memory-access-uma-and-non-uniform-memory-access-numa/)
+and more importantly going through the steps of setting it up, higher power
+draw, and with that noise, I quickly ruled them out. I set my eyes on the [Epyc
+7551p](https://www.techpowerup.com/cpu-specs/epyc-7551p.c1929) and the
+[Supermicro
+H11SSL-NC](https://www.supermicro.com/en/products/motherboard/H11SSL-nc)
+motherboard to cover every single thing I wanted out of the system. At the cost
+of about $700 USD to fully replace the core of my old system, I felt like this
+was a reasonable price for what all I get.
+
+## Specs
+
+- [AMD Epyc 7551p 32 core (64 thread)](https://www.techpowerup.com/cpu-specs/epyc-7551p.c1929) 
+- [Supermicro H11SSL-NC](https://www.supermicro.com/en/products/motherboard/H11SSL-nc) 
+- 128GB Samsung 2133 Registered ECC
+- 2x256GB [Inland Professional SSD](https://inlandelectronics.com/product/inland-professional-240gb-sata-ssd/)
+- 3x10TB Western Digital drives (white label pro red)
+- 2x1TB [Crucial MX500](https://www.crucial.com/products/ssd/crucial-mx500-ssd)
+- 2x2TB [Intel P3600 PCIE SSD](https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/intel-ssd-dc-family-for-pcie-brief.pdf) 
+- [Fractal Define R5](https://www.fractal-design.com/products/cases/define/define-r5/black/)
+- [HP NC550SFP](https://www.hpe.com/psnow/doc/c04111686?jumpid=in_lit-psnow-red)
+- LSI SAS HBA

+## Build issues and complications
+
+Over all, this was a fairly simple build in terms of hardware. The Motherboard
+is *mostly* ATX standard with one exception (photo later). One oversight I had
+was not having VGA anything to hook up to the system when it showed up. The
+onboard video is forced to be the only enabled display by default, and I should
+have seen that coming. IPMI is also disabled by default, so wasn't able to even
+remote into it until I got a display out.
+
+Turns out it's *mostly* ATX. Whoops, need to remove a standoff.

+
+
+## The plan!
+
+The current goal is to get it running on Proxmox to allow for easy separation of
+duties, and isolation of public/private hosted services. I'm planning on running
+something to manage ZFS and act as a SAN for the network, probably [TrueNAS
+Scale](https://www.truenas.com/truenas-scale/) as I have recommended that many
+times, and want to see what it's like today, despite knowing well how to manage
+a fully headless system. I'm pulling out a second gen Ryzen 8 core system of the
+network, so I'll also be creating a virtual machine to directly replicate it's
+place to make transitioning easy. After that, it's up to whatever I want. I'll
+be hosting a semi public [Nix Hydra](https://github.com/NixOS/hydra) instance
+for friends since I have too much CPU grunt going to waste. I'll also be able to
+turn back on transcoding on my [Jellyfin](https://jellyfin.org/) server as I
+know this should easily be able to transcode 4 or more streams while leaving
+plenty left for the rest of the services. After that, who knows.
+
+What it looks like thus far.
