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 ADS BLOCK0 FETCH SERVICE TO COMMUNITY

With Jormungandr 0.8.11 you can fetch the genesis block with http(s). Enabling this functionality will not only reduce load on the IOHK trusted peers, but also reduces your bootstrap times, all you need to do is add the fetch block0 service in your node_config.yaml or in node_config.json.

JSON configuration

{
  "log": [
    {
      "format": "plain",
      "level": "info",
      "output": "stderr"
    }
  ],
  "http_fetch_block0_service": [
    "https://adanorthpool.com/bootstrap"
  (you can add multiple addresses here as well)
  ],

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.

A glance into ANP Server

I tought I would share my current screen setup on the server. I am using terminator bash terminals and hardware monitoring is your standard stuff like Glances, Htop and Iotop. But also I use Chrony for making sure my system clock is up to date and tuned to make sure my network is up to date, both running as services on the computer. I had my own custom made scripts for forking / bootstrap checking but replaced them with the great script Redoracle made. I also run Prometheus, Grafana and Nginx for monitoring and websites and a few security measurements, one of them that I think its fine to mention is I run Fail2ban. I have removed some information that could affect security and replaced with a red bar.

Some of the hardware monitoring. I have a default view and a view also with background scripts (for example I check how well Chrony is doing in making sure my system clock is as accurate as possible)
Currently the hardware is running a main server, 2 nodes and one extra server that I am helping IOHK out testing with. I run an error parser script and I also run the great script from Redoracle mentioned above and with Github link to its repository if anyone else wants to use the same. As you can see from the above pictures we have plenty of hardware resource room to grow utilizing somewhere around 10-15% CPU and around 10% of memory. Connections vary between 2000-4000 and tracked connections are around 13000-15000. In the “do stuff” box I run scripts from time to time like checking how many files open on the system (usually 18000-20000 at any given moment) or watt usage of my Nvidia card (sadly around 18 watt so more than what I expected but luckily since CPU is only at 10% utilization the Ryzen draws less power than what I expected as well.)
