ANP joins friends and family testnet and adds hardware based encryption for cold staking keys

Ada North Pool had the great honor of being asked to join the friends and family testnet. The TLDR is the progress is great. Overall the experience has been great and documentation, features and overall experience is shaping up well in the opinion of this pool operator.

We also added a hardware encryption usb drive in preperation of cold staking key storage.

Fingerprint identifying 256-bit AES hardware encryption usb.
View of a core node and a relay as of today 14th May.

The nodes come prebuilt with a lot of features that can be enabled. For example the EKG view that you can set to a port on your localhost.

EKG view of cardano-node with a lot of data.
With a Prometheus exporter built into the node it is really easy to setup Grafana data as well.

ANP New server/node structure overview and update on [email protected]

An overview of the latest node structure for Ada North Pool (ANP).
Attribution for logos used: Computer Vectors by Vecteezy

To end the testnet with a bang we have upped our efforts even more. We added two Germany based xeon 4core computers on 1gb fibers at one of the datacenter of Hetzner where we are now both [email protected], practicing with cardano-node swarm (manager/[email protected]) and also adding block propegation for jormungandr to improve our chances of winning slot battles. For our home servers we have a local swarm on its own network (lan based) for the cardano-core that is in touch with the cardano relay nodes (in ip addresses relay1.adanorthpool.com and relay2.adanorthpool.com and also the remote servers @ relay3 and relay4) and thus should work fine even if one of the internet falls down. We also have full UPS backup in both the home servers and in the datacenter. I think we are now on a path to become far more secure in our operations even in the event of internet failures or power outages.

[email protected] is going solid with participation previously by the whole ANP family of computers. Onwards we will be using ANPLAPTOP (4 core) ANPSERVER2 (its a 12 core so have idle capacity for this) Both the ANPHERTZNER servers (4 core) + ANP FAMILY computers that are 8 core and 4 core and with GPU computation as well.

We are currently participating with a good deal of computation for the Cardano team. Stats can be viewed @ https://stats.foldingathome.org/team/244483
Main jormungander server with a pool and 6 nodes.
The main server also hosts a core cardano-node (2nd network lan) and a cardano-node relay (internet)
ANP server 2 hosting 4 cardano-node relays. Server is also [email protected] on light setting.
ANP Hertzner servers the two cardano-node relays are up and running. The jormungandr propagators one is up and other is boostraping soon to be up as well. Both ANP Hertzner servers also run [email protected] on light to help support the cause.

ANP 2. SERVER EQUIPMENT STARTS ARRIVING

Today the first batch of equipment for our second server arrived. We are considering naming our second server oro8 after the Oroborus snake of life/death cycles with the 8 symbolizing the eternal ring cycle. But probably we will name it ADA NORTH POOL 2 (ANP2). Main server will use Ubuntu for stabile operations while the 2nd server will use the more rolling updating distro called Manjavo for faster implementation of new kernel/hardware support. The stable server will likely host the pools and the more rolling updating server will hold a majority of nodes (but both will run nodes).

New hardware structure for ANP with a total of 24 cores (20 not including test laptop) and 136GB ram (128 not including test server) and above 10TB of disk space. Icon graphic: Appareil Photo Vectors by Vecteezy

ADA NORTH POOL PLEDGE TO SUPPORT POOLTOOL.IO

As we are not stronger than the community we build around Cardano ANP has decided to divert back founding into supporting projects in the ecosystem on top of supporting charity projects. First up is Mike Fullman’s pooltool.io that has become a central hub for information regarding pools performance. To be clear in no way will us supporting pooltool.io make us have any special relationship with the site and they will report our performances correctly as can be verified from other explorer sites as well.

ADA North Pool has pledged 5 usd per month to support Mike Fullman’s effort www.pooltool.io

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)
