This page is dedicated to my 42u Server Rack and the servers contained within it, or something along those lines for anyone who is interested. I’ll also give a rough estimate on how the whole thing has cost me thus far at some point within this page.
Specifications
- Cisco SG200-26 (26 Port Switch)
- ThinkServer RS140 w/ 32GB RAM, 1.2TB HDD, 4 Cores
- ThinkServer RS140 w/ 8GB RAM, 300GB HDD (Used for small docker containers), 4 Cores
- HP ProLiant DL360p G8 w/ 32GB RAM, 3 .approx TB HDD/s (waiting for 4 more caddies), x2 8 Core CPUs (16 Thread), total of 16 Cores, 32 Threads.
- HP ProLiant DL380 G7 w/ 8GB RAM, 7.5TB HDDs
- My Friend’s Server: HP ProLiant DL120 G7, 20GB RAM, (undisclosed storage), 8 Cores
- Dell Poweredge R230 – being fixed up :), planning to add 64gb ram (ddr4) and 16TB worth of storage
- PiKVM w/ 4gb RAM & 64gb storage (sd card lol, since it is a raspberry pi and I’m lazy) coupled with a lovely HP KVM Switch
I am averaging a new server every 2-3~ish months, which honestly probably isn’t a great idea. The cost of power isn’t too bad, just have to keep a close eye on the wattage. I plan to get a lovely rack-mounted router instead of using a crappy eero 6 (because I’m a lazy bean – yeah that’s it). The eero isn’t all that bad – around 2.5Gbit/s LAN speeds, and local rack speeds of around the same.
Storage & Stuff
Please Note: not all of these drives are currently in use lol (aka I need to buy a storage array server) yippee!!
- x1 10tb 3.5″ SATA
- x1 4tb 3.5″ SATA
- x10 4tb 3.5″ SAS
- x10 3tb 3.5″ SAS
- x2 1.2tb 2.5″ SAS
- x1 1tb 2.5″ SATA
- x20 900gb 2.5″ SAS
- x1 600gb 2.5″ SAS
- x2 300gb 2.5″ SAS
- x1 146gb 2.5″ SAS
This totals to approximately 106.745~ terabytes. Funsies!! Some say this is way too much storage, but you can never have too much!
Now, aren’t Ethernet Cables fun?
- x50 Mixed Length Ethernet Cables (around 300 .approx ft) – CAT6
- x30 ✨ sealed ✨ short-length Ethernet Cables – CAT6
- x25 also sealed meh-sized 1m-ish Ethernet Cables – CAT6
So around 105 total ethernet cables (still think I’m sane? ahhahaha)
General/Operating Costs
As we all know, the average British electricity bill is pure bullsh*t – 23.51p/kWh is my current tariff, however I have a sneaky trick up my sleeve!
Electricity Costs (Operating Costs)
Using my servers’ built-in power meter and power capping features I can lower my costs my around £30/mo. For example, using iLO4 I set my DL360p G8’s power cap to 80w which equates to around 0.08kWh. This means that my total cost for the DL360p G8 is £13.53 to run 24/7 each month even though the power supplies within the server count up to 750w each (x2 PSUs however one is redundant).
However, on the other hand, a Raspberry Pi 4B (e.g. my PiKVM, which uses a RPi 4B) uses hardly anything!
This was calculated with the power tariff at 23.51p/kWh.
| RPi State | Power Consumption | Cost (GBP) per / hour |
|---|---|---|
| Idle | 540mA (2.7w) | 0.0534 |
| ab -c 100 -c 10 (uncached) | 101mA (5.1w) | 0.119 |
| 400% CPU Load (stress –cpu 4) | 1280mA (6.4w) | 0.1504 |
It is unlikely that the PiKVM will be running at 400% load, thus for a monthly cost-basis I’ll base it off the uncached model. Therefore, it would cost around £0.8627 to run a RPi 4B for an entire month. Mind you, the price of electricity is finally getting cheaper again, so when my tariff updates, I will also update this (estimated around 21p/kWh – yippee!)
