ADA North Pool officially on the 0.8.2 ITN

ADA North Pool joined the official 0.8.2 Incentivized Test Net (ITN) Friday the 13th December 2019. We look forward to providing staking to all of you and a glance at shows the competition will be stiff with the delegator the one to benefit. I hope you would still consider our pool among the other great pools on offer and hopefully we can all together make this ecosystem thrive.

On another note I made a typo for the ITN description and the pool is described with only 1 TB of RAID 1. In actuality the pool has 2 X 4 TB Seagate Enterprise Exos disks together with two Kingston A2000 500GB NVMe’s. Will update it at some point later in the test phase.

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.

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

Ada North Pool invests in dedicated server for staking pools

To prepare for the coming testnet period with incentive rewards ADA North Pool has invested in hardware that should scale well for the next coming years. Here are some of the highlights (most brands are left out for security reasons):

For redundancy we have gone with two 1200 watt UPS from PowerWalker that will be our backup source both for the routers to keep internet up and running but also for the computers to keep them running during a power outage.

Two 4 Terrabyte enterprise disks in raid 1 that are tested and meant to run 24/7 and with a high reliability and long age before mean time of failure. Draws roughly 10 Watt in operational mode and some 5 watts in idle mode. The reason for such large capacity was a study I did where I saw on main net the largest epoch could consume up to 1.7 Gigabytes of disk space. So to scale well for the future we have room for 4000 gigabyte 🙂

Two NVME 500 Gigabyte disks for the server operation system. Draws around 2 watts in operational mode and less than a single watt in idle mode.

64 Gigabyte of 2666 MHZ error correcting ram. This will make sure the server is stable in a 24/7 environment where you could risk with regular ram having at least an 8% chance of a failure on regular types of RAM per year according to some studies, but these RAM are error correcting so will avoid this risk.

Ryzen 3700X for 8 cores (16 threads) at only 65 watts. There are some tweaks out there and I will be looking into lowering the wattage to around 45 watts hopefully as I want the staking pool to be as energy efficient as possible.

Finally while I will not detail the motherboard and what type of lan chip it uses, what I can say it is is a very highly regarded and has received many awards regarding stability and energy efficiency and LAN performance. The same goes for a new router that is ordered that has a very high input/output and high hardware specs and enterprise level security solutions.

Ada North Pool joins private testnet for statistical data exploration

In the last week I have joined a private testnet where we with the help of script collect jcli data and can aggregate the data with others who have joined the testnet. This allows us to understand better for example memory growth compared with number of transactions on the blockchain or how the blockchain database grows. This gives us a better idea on memory requirments, disk requirements and such. I joined after the first article was published ( ) but I am honored to be part of such a group.
