ADA North Pool Video introduction and update on server

So encouraged by Charles post on staking pool making videoes I created one today that you can find here https://www.youtube.com/watch?v=pZ4dlmw_Dsg

Currently I just need to do some cable managment but as you can see we are running straight from ISP to pool.

ANP Installs dedicated fiber connection

In these Covid-19 times trival news like this is perhaps not that important but it is an important milestone for ADA North Pool. Today we connected a 1 gigabyte dedicated connection straight to the pool’s Mellanox network card this should help tremendously with capacity as we can now fully unleash the 1 million tcp packet per second capacity of the network card.

ANP 2ND DEDICATED FIBRE SCEDULED FOR INSTALL WEEK 11

I got word from the 2nd fiber provider (Homenet) that they are coming to install the fibre connection in week 11. That means we will have more redundancy for ANP with one fibre connection dedicated and connected straight to network card and the home fibre connection as a 2nd fibre connection. This should help with robustness for the server and is a stepping stone towards also full redundancy with either 5G or Starlink internet whatever is provided first. (likely 2021-2022).

ANP Transceivers and cable equipment arrive

It took a while but I am really happy with the custom made trancievers from fs.com that will fit to the brands of my network cards at a fraction of the cost if I bought it directly from the network supplier. This means we will at some point soon have a downtime but I want to have a good epoch – so far we have done 18 out of 19 and we could make up to 10 more this epoch. Given we had some poor luck in draws last two epochs that means I want to wait a bit before doing the rest of the networking equipment. I will update on twitter when the server will have some downtime.

Update on ANP Servers

We had a few rough periods and needed to rethink our approach. In that regard we made a new server structure as can be seen below in the image.

This has improved our stability and now our main pool server has had an uptime over a day without any problems. We are converting now around 82% of blocks an improvement of 75% from previous settings.

Finally an update on network equipment: Router has arrived and network cards as well. But we are waiting for the transceivers / cable equipment. Probably by next week we have everything and ready to install. The installation is likely to take half a day or with maximum preparations I could probably manage to get the pool up and running again in 1-2 hours. I will try to select a point in between blocks that is optimal – probably during next weekend.

ADA North Pool invests in new router hardware

ADA North Pool invests in the Mikrotik RB4011 for more powerful router hardware, this gives us capability to utilize some of the amazing performance of the Mellanox Connect-X 4 cards we have purchased. The router can handle roughly 5-5.5 million packets per second worth of routing small packages of 64 bytes (typical for staking pools who only need to transmit small info to each IP address)

ADA North Pool invest in network equipment

As a first step to a potential data center class capability ADA North Pool as purchased both a Mellanox ConnectX-4 MCX4111A-XCAT 10Gigabit Ethernet Card and a Mellanox ConnectX-4 MCX4121A-ACAT 25Gigabit Ethernet Card. In theory these cards can in optimal situations handle 75 million TCP packets of information per second.

ADA North Pool moves main server to SSD

With a very high input/output for our files I have decided that its more important with NVME SSD performance for input output file operations than 4Terrabyte of RAID and will likely switch over to full NVME hardware if we are successful in the Testnet period. It also has the side benefit of a 90% less watt usage per disk.

The Making of Ada North Pool server

Had a fun weekend with my daughter Hannah helping me build the server and throwing in a ton of gaming stickers on every surface of that server for good luck charms 🙂

Hannah with a helping hand
I am quite happy with the cable management here.
Clean server. Maybe in 1 year or so I will do an update on how the server looks (and obviously maintenance.
I am always happy when I have a screw loose that I can put back in its place 🙂
2 UPS and server where they will hopefully reside for a while going forward.
One of the screens of the server during testing. (0.8.0 RC3 not doing that great.)

Server hardware starts arriving

I had some qualms regarding showing hardware or not because it is an issue of security vs building trust in community. I landed on thinking I have security measures as a “fish” in the big ocean and that if I scale I would probably buy more equipment and security measures. Besides – its fun learning this as I go along and nice to enjoy comments and feedback from readers in that journey. I am pretty happy the powerdraw will be around 65 watt max even for a server that has a lot of horsepower. So without further ado here are some current hardware that I picked up today:

One UPS for server. One for network. Overkill? Perhaps 🙂
32 GB ECC ram. (32 more on its way for 64GB total). Sadly no 3200 MHZ ram only 2667 MHZ available in unbuffered ECC in market (as far as I am aware)
Ryzen 3700x and Arorus motherboard with latest Intel LAN chips and room for a lot of disks.
2x 4TB enterprise disks and 2x 500gb NVME
