ARM-Based Web Cluster – Build Log Part 1

After doing extensive research on single board ARM-based computers I decided to build my own cluster. The purpose of the ultra low power cluster is to develop new applications with the most recent software technologies and host few production websites. Yes, I know, I’m crazy! 😀

My research showed that previous clusters lack significant calculating power and they’re based on performance limited (hardware) boards like Raspberry Pi 2, Raspberry Pi 3 and PINE A64+. The main problems with those boards are the RAM, the limited I/O of the microSD cards (limited to 25 MB/s on Pi 2 and Pi 3), and the network speed (10/100).
Those boards are more suitable to be used as development boards. Often microSD card speeds are limited to 25MB/s (on Pi 3), which means that even if you buy UHS-II and UHS-3 cards you won’t be able to utilize them at their full speeds.

I’ve looked closely at the ODROID single boards – those have powerful CPU (Quad and Octa-core A53 and A15), fast Gigabit network (10/100/1000) , 2GB RAM USB 3.0, eMMC support.

For my build I’ve chosen the following hardware

Parts and single-boards – www.ameridroid.com

Web and Caching Nodes:
ODROID-C2:

 

Web Server Nodes:
ODROID-XU4:

We benefit from faster more capable CPU, eMMC (up to 400MB/s capable eMMC5.0) speeds, USB 3.0, Gigabit network and 2 GB of LPDDR3.


Database Nodes:
ASUS H110S2/CSM Mini-STX (Installing Percona With TokuDB MySQL Server)

For our cluster we will start with:

  • 1 proxy node
  • 2 load balancer nodes
  • 2 web server nodes
  • 1 database server node

Our final goal is a cluster with:

  • 1 proxy node
  • 2 cache nodes
  • 8 nodes in web cluster
  • 10 nodes in MySQL cluster and 2 nodes in NAS cluster. Total 23 nodes.

We may not be able to fit that many nodes in this printer case, because the power supplies needed to power all the nodes will require a lot of space.
