We were looking at this for a CI/CD pipeline that was focused on Arm CPU performance.įinally, there is how you get there. Still, if you are using the GPU, SBCs are admittedly better. NVIDIA announced Arm support for GPU accelerated computing so that would probably be how we would add this to our ThunderX2 design. The Raspberry Pi 4’s have an integrated GPU that we are not using here. The Gigabyte ThunderX2 server also has features like hot-swappable power supplies and out of band management which makes it easier to integrate into a data center. The Raspberry Pi 4 is not fully SBSA compliant so one ends up using embedded images or special installers. First, the ThunderX2 system runs OSes out of the box. Conversely, if that single server fails, everything goes down. A failure may not take down the entire cluster, but it is much more likely to happen than on a single server. The Raspberry Pi 4 4GB cluster has a total of 190 nodes, 9 switches, and 1 NAS for 200 systems that can fail. That means that the recurring costs are $125-150 more for us each month. Our Silicon Valley labs use $250-300 per KW provisioned each month. In our Updated Cavium ThunderX2 Power Consumption Results, we saw under 900W. The nine switches can use ~40W each without PoE power for the nodes.
If rack space is valuable, you can use your TCO calculator to compare those figures.Īssuming 5W for the Raspberry Pi 4 4GB that is 190×5= 950W of power for the nodes. All told, this solution takes 26U in the best case. We also need to put that FreeNAS Mini XL+ we are using somewhere.

We also have an aggregation switch plus eight 24-port PoE switches for a total of 9U worth of switches. That means we have 4x 4U or 4x 5U for the shelves with the nodes. Each shelf requires a minimum of 2U but to remain serviceable most organizations leave 2-3U of extra space above the nodes in racks. In terms of rack space, the Raspberry Pi 4 solution uses four shelves with 48 nodes each. The initial purchase costs are only part of the equation. Since someone will undoubtedly want the 220 number, it is 53% or 2.14x more. That means that you end up paying about 1.85x to use “low cost” SBCs instead of a server.
Using our 190 Raspberry Pi 4 4GB cluster, the ThunderX2 is about 46% less expensive. In the end, here is the back of the envelope of what we came up with: Marvell ThunderX2 V Raspberry Pi 4 4GB Cluster Cost Comparison 190 Raspberry Pi 4 4GB’sĪs you can imagine, what started as a simple ask, took a few weeks to get through.

The class is free and all necessary technology is provided by our generous sponsors.ĭetails and resources regarding the 2014 Kid Tech classes will be posted here.Putting it Together: Marvell ThunderX2 v. The goal is to introduce kids to programming and creative problem solving using technology. This class is based on the amazing Raspberry Pi single board computer.
There are still a couple of openings, please contact us if your kid is interested and available Tuesdays & Thursday for the next 3 weeks. In addition to the technical challenges, the class will also need to solve real-world problems related to mounting and packaging the equipment in a box and on the balloon, processing and compiling video from the resulting images and dealing withe the shipping vendor on pricing and logistics.
#PFSENSE RASPBERRY PI 2019 HOW TO#
Kids will learn how to build and set up a Raspberry Pi computer, and will write an intervalometer program to take a photo every x seconds.
#PFSENSE RASPBERRY PI 2019 INSTALL#
Install a Raspberry Pi in a cardboard box with a hole for the camera and mail the box via FedEx while taking photos every 30 seconds. The class is based on the Raspberry Pi single-board computer and the goal is to introduce kids to programming and creative problem solving using technology. Participants will each build and program a Raspberry Pi and camera module to complete two photo based projects.Īttach a Raspberry Pi to a large helium weather balloon on a very long string and program the Pi to take photos from above. This summer we are offering a class on computers to Kids age 9 and over in Santa Barbara. One of our goals at Outside Open is to pass on the love of technology to others.
