Your system's proportions

Hi, I am wondering how big are the FreeBSD systems you are using? Would you care to share your storage size, memory, network bandwidth, number of file systems?
Let me kick it off with two of my boxes:
  • NAS
% zpool list
NAME      SIZE  ...
storage  14.4T 
zroot    31.8G 

# grep -i memory /var/run/dmesg.boot
real memory  = 17179869184 (16384 MB)
avail memory = 16428228608 (15667 MB)

% sysctl hw.model hw.machine hw.ncpu
hw.model: .... @ 1.50GHz
hw.machine: amd64
hw.ncpu: 4

# Network: 2x Gigabit Ethernet

% zfs list | wc -l
  • And the same on a production VM:
% zpool list
NAME    SIZE  ...
zroot  59,5G 

% grep -i memory /var/run/dmesg.boot
real memory  = 16106127360 (15360 MB)
avail memory = 15571709952 (14850 MB)

% sysctl hw.machine hw.ncpu
hw.machine: amd64
hw.ncpu: 4

# Network: 1x virtio (routing via gigabit ethernet)

% zfs list | wc -l
My Raspberry PI 4B

I modified the sdcard image so I could do a fresh install from it onto an m2. ssd with a ZFS root.

Pfew. You ready for it?

One of my oldest systems, a server named Molly. Has had many incarnations, mainboard swaps, storage added and whatnot over the years. It was my only "server" (besides Maelcum; the firewall) until I built Hosaka. It's a Core i5-3470; 16GB memory. LSI SAS9207-8i for all the disks. Intel 1000/PRO network card. Serves most of my media content, shares and I build my repositories on it.

Maelcum, my firewall, connects the internet (600Mbit Cable internet) to the rest of my network. It also acts as a router between VLANs. Maelcum has had many incarnations too, it started off with an old trashed Siemens Pentium 90 and a Telis BRI ISDN card. Been having some throughput issues with it but that might be due to the rather under specced hardware. May need to replace it with something newer, it's getting old (judging by the SSD lifetime it's almost 8 year old hardware).
# Intel(R) Celeron(R) CPU 847 @ 1.10GHz Onboard passively cooled CPU mainboard
# Single drive zroot (standard install) on a Kingston 60GB SSD (has a whopping 69102h power_on_hours and still no errors)
# Two Intel PRO/1000 network cards

Hosaka; my VM 'beast' I cobbled together some time ago from an old trashed server. It's a dual Xeon E5620 with an onboard mpt(4) controller, 4x1GB igb(4) (Supermicro X8DT3-LN4F) and has 96GB ECC RAM. As you can see I run a number of VMs on it, most of them FreeBSD too. It's old hardware, slow in comparison to more modern boards and CPUs but it works good enough for what I use it for.

Williscorto; A Zotac ID80 plus. Mainly runs a FreeBSD desktop to test FS-UAE on. It's getting a bit slow, still has the original 5400 RPM HD in it, might replace that with an SSD. Plain and simple, default ZFS layout.

ChibaCity; A Zotac Zbox Giga ID72 plus. Hooked up to my AVR/TV. Plan to put some emulators and media players on it. Haven't gotten the time for it yet. It runs a few things now but mostly all unfinished tests.

PiBSD; A Raspberry Pi 3; Using it with a minipro TL866 programmer, mostly use it to code 6502 assembler on it and burn it to an EEPROM.

I have two desktop machines too, but they run Windows 10 only, you probably don't want to know about those ;)

The whole thing is tied together with a HP Procurve 2530-48G (48 x 1GB ports). Which was donated to me, after I replaced it with newer equipment for a client.
Why bastille and not a plain /etc/jail.conf ?
Easier to create and manipulate jails without having to think about all the difficult bits. The fbsd1/jails datasets are the 'old' jails, I used to built them by hand but it was just a bit of a chore to keep them updated. Bastille made that really easy.
C64 and Amiga software I collected over the years. Is that a lot? I'm a bit of a hoarder and I kind of lost track :D
Pretty much, I also have a huge amount of software I collect from retrostuff (Commodore, MSX, ZX, TRS, etc) but my entire Commodore thing is something near 36G.
As this is off-topic there are some really good C64 games.
Ever programmed sprites ?
I made drawings on paper and then counting the digits, adding powers of two, this was like 34 years ago.
And detecting things like collision.
Programming with backtracking in dos.
Later in life came unixware and SCO-unix.
Home server / NAS / internet router:
Intel Atom, 32bit, 1.8 GHz, 4 core. Physically 4 GiB RAM, but being a 32-bit machine, only 3 GiB get used.
Two 100-base T Ethernet ports, one is the internal home network, other goes to my ISP via DSL. WiFi is provided by a commercial AP installed on the internal wired network.
Boots from a 32 GiB (!) Intel SSD which is now 5 or 6 years old, but works great. Has a second identical SSD inside, which is set up for emergency booting if the first SSD fails.
Contains two SATA disks which form the main file systems, mostly RAID-1 (straight mirroring) in ZFS. One 3TB, one 4TB. The extra TB is used for a file system that gets very little use and is not important.
An external 2 (or 4?) TiB backup disk is connected via USB-3 and a 6' extension cable. That backup disk is physically in a big safe with very thick walls, which happens to be right next to the bookshelf where the server sits.
De-facto headless. It has a tiny keyboard and a 12" VGA monitor attached, for occasional local administration when the network fails.

I've also got a Supermicro 2U server waiting to be set up (bought a couple of years ago before a house move the ended up taking about two years 😅, now just waiting to get cabling to/from the garage/workshop):
  • 2x Intel Xeon E5-2630L
  • 64GB memory
  • 12 drives - think it'll have 41TB of space total, but realistically will be much less as most drives will be configured into mirrors
  • LSI 9200-8i
  • 4x Gigabit NICs
I'm running FreeBSD 13.0-RELEASE-p4 64 bit as on a small NUC with 2 Gigabit NICs.

CPU: Intel(R) Celeron(R) N4100 CPU @ 1.10GHz (1094.44-MHz K8-class CPU)
128 GB SSD
ZFS only

It's my internet firewall/gateway, and thanks to the magic of bhyve it also runs FreePBX.

It does its job, and it basically bored all day long. Required administration is neglectable. So doing a great job!
I am running FreeBSD 13.0 on a Raspberry Pi 400. See here for specs.

All my FreeBSD systems are VMs these days, except for the ZFS server, which I just rebuilt with a new Motherboard, CPU, and memory, from otherwise existing parts after the old motherboard died:

The new motherboard has 2 x M2 sockets and 8 SATA ports, but I'm still using the old Avago Technologies (LSI) SAS2008 SAS/SATA controller for the tank.
Active: Ryzen 5 1400 (3.4 GHz), Asus B350-Prime mobo, 32 GB RAM, Asus Raadeon RX 550 4 GB, two 240-GB SSD's (one is an ADATA, the other a Zheino, both with FreeBSD 13-RELEASE, and a 400W EVGA PSU. That one, I plan to use as a build/repo server, because it's been incredibly reliable, doesn't complain at overnight jobs. First rig I ever built from aftermarket parts, back in 2017.

Building in progress: Ryzen 7 5800x, Gigabyte x570 UD mobo, 32 GB RAM, Aorus RX 6900 XT 16 GB with a waterblock, a Gigabyte 240 GB SSD. Trying to mate a Be Quiet! cooler to the GPU, just ordered the fittings to connect the hoses. 😤 Oh, and the PSU is an 850W thingy by Gigabyte, as well. Hoping to finish building it before November, and start setting up FreeBSD on THAT. I know, there are water-cooled GPU's on the market that are complete systems (with pump/fans/radiators/reservoirs), but there was nothing from Gigabyte. I decided that's not gonna stop me, I'll come up with something.

I have to admit, I am jealous of forquare 's Epyc setup, but after pricing some builds, I realized I'd rather blow my money on SSD storage, and use FreeBSD to serve it up.

Let me ignite a little bit more jealosy then :). I am a proud owner of a ThreadRipper 16 core. :) I have to take a look into getting one of those 3-rd gen 64 core TRs. :)

I'd probably best point out that the Supermicro not as impressive when you realise that all of the disks are old - which isn't very smart...
It was bought on a budget: in 2019 I sold my 2008 Mac Pro for around £600, and bought this system (from here, if anyone is interested) with the funds to have some fun with. Some disks I bought refurbished, other disks came out of an older NAS. The sticks of ECC RAM I saved from a skip, something like 256GB in all, about half of it had errors reported in memtest so got returned to a skip...

One of the often asked questions is, "how do you build a home lab?". Well, dumpster diving is a good way to get some descent equipment. You will find lots of duds but also some good stuff people just chucked away because it's "too old". Companies typically buy new hardware every 3-5 years and trash the old stuff. But enterprise grade hardware is usually built quite solidly and would probably last a lot longer than that. Not good enough for the company anymore but certainly good enough for a couple of more years in someone's home lab. When you actually work in IT it's a bit easier to get but if you're not working in IT you can just ask friends and family to keep an eye out and let them know you're willing to take some of their old stuff they're going to throw away. In all cases, ASK if it's ok if you take it home. Some companies I worked for were very strict when it came to removal of old equipment, that was always handled by specific rules. Other companies were very happy if you took away their "trash".
The cheapest mobo for a Threadripper is around $300 USD.... For an Epyc, a compatible mobo is closer to $500 USD. A 64-core Treadripper goes for around $5k. I have to ask myself, "What am I doing that really demands the capabilities provided by a Threadripper setup that cannot be met by a recent AM4-compatible setup? A 1st-gen 8-core Threadripper goes for around $200 USD, but still commands a $300 and up mobo, and eats more power (180W) than a $400 8-core Ryzen 7 5800x (105W).

One reason I'd rather not go looking for discarded equipment - it's kind of a time sink to find it, test it for compatibility/durability (And discover it's a dud that needs tossing), keep an inventory, etc.
