Mixtile reveals U.2 to PCIe/SATA breakout board for Rockchip RK3588 cluster

Mixtile Blade 3 cluster: boards connection

Mixtile Blade 3 is a Rockchip RK3588 SBC with up to 32GB RAM designed for server applications, notably to build clusters through a U.2 edge connector with 4-lane PCIe Gen3, SATA 3.0 to interconnect multiple boards. What was not clear so far is how multiple boards would be connected, as we were just shown two boards connected by a U.2 cable, which does not scale, and does not provide power as the 12V input also comes with the U.2 connector. The company has now provided more details showing how it’s done, namely through a breakout board that connects to the U.2 edge connector, and allows cluster design as shown below. The U.2 breakout board comes with a 6-pin connector 12V power, pair of SFF-8643 (mini SAS) connectors for PCIe daisy-chaining, and a SATA port. Since short SFF-8643 cables are hard to find, Mixtile will provide custom 15-cm cables with the […]

Rockchip RK3588 Pico-ITX board launched with four-node cluster box (Crowdfunding)

Mixtile Blade 3 SBC

The Mixtile Blade 3 Pico-ITX single board computer (SBC) powered by Rockchip RK3588 processor has now launched on Crowd Supply with either 8GB or 16GB RAM, and an optional four-node cluster box with a built-in PCIe switch designed to accommodate four Mixtile Blade 3 boards. The board also comes with up to 128GB of storage, two 2.5GbE interfaces, HDMI 2.1 output, HDMI 2.0 input, USB 3.2 Gen 1 USB Type-C ports, as well as a mini PCIe Gen 2 for expansion and a 30-pin GPIO header for expansion, as well as U.2 edge connector with 12V, PCIe x4 Gen 3 and SATA signals to interface with other Mixtile boards and build clusters. Mixtile Blade 3 specifications: SoC – Rockchip RK3588 octa-core processor with four Arm Cortex-A76 cores @ up to 2.4 GHz, four Arm Cortex-A55 cores, Arm Mali-G610 MP4 quad-core GPU with support for OpenGL ES3.2, OpenCL 2.2, Vulkan1.1, 6 […]

Turing Pi 2 mini-ITX cluster board supports RK3588 based Turing RK1, Raspberry Pi CM4, and NVIDIA Jetson SoMs (Crowdfunding)

Turing Pi 2

We first covered the Turing Pi V2 mini-ITX cluster board supporting up to four Raspberry Pi CM4 or NVIDIA Jetson SO-DIMM system-on-module in August 2021. The company has now launched the Turing Pi 2 on Kickstarter with a little surprise: the Turing RK1 module with Rockchip RK3588 Cortex-A76/A55 processor and up to 32GB RAM. The board allows you to mix and match modules (e.g. 3x RPi CM4 + 1x Jetson module as on the photo below), and with SATA ports, Gigabit Ethernet networking, USB 3.0 ports, mPCIe socket, you could build a fairly powerful homelab, learn Kubernetes, or self-host your own apps. Turing Pi 2 specifications: SoM interface – 4x 260-pin SO-DIMM slots for up to four Raspberry Pi CM4 with Broadcom quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (adapter needed) NVIDIA Jetson Nano/TX2 NX/Xavier NX SO-DIMM system-on-modules with up to 6x Armv8 cores, and […]

ClusBerry Rack houses up to four hot-swappable Raspberry Pi CM4 modules

Clusberry Rack

TECHBASE ClusBerry Rack supports up to four Raspberry Pi CM4 based modules which can be added and removed on the fly thanks to a lockable mechanism that reminds me of hot-swappable drives found in NAS. Using the same ClusBerry I/O mainboards as found in the earlier ClusBerry 9500-CM4 and ClusBerry-2M industrial systems, each Raspberry Pi Compute Module 4 inside the ClusBerry Rack offer one Gigabit Ethernet port, one USB host, one micro USB service port, and an RS-232/485 serial port. TECHBASE is not the best company when it comes to describing its products, possibly because those are customizable, and in this case, they don’t show the other side of the enclosure with all ports… But based on the PDF we’ve received, you should be able to create a system with four modules offering the following features each: Optional video output – HDMI Networking – 1x Gigabit Ethernet port (option for […]

Turing Pi V2 mini-ITX cluster board takes four Raspberry Pi CM4 or NVIDIA Jetson SoMs

Turing Pi v2 mini-ITX cluster board

The Turing Pi V2 is a mini-ITX cluster board that builds on the  Turing Pi mini-ITX cluster board taking up to 7 Raspberry Pi Compute Modules introduced in 2019, but instead supports up to four Raspberry Pi CM4 (Compute Modules 4) or NVIDIA Jetson Nano/TX2 NX/Xavier NX SO-DIMM system-on-modules. The Turing Pi 2 board is equipped with two Mini PCIe sockets, two Gigabit Ethernet ports, two SATA III ports, four USB 3.0 ports, a 40-pin GPIO header, and a 24-pin ATX connector for power. Since board-to-board connectors – as found in Raspberry Pi Computer Module 4 – are not ideal for density, the company went with a design including 260-pin SO-DIMM connectors plus CM4 adapter boards, a design that allows them to also integrate other SoMs like the NVIDIA Jetson SO-DIMM modules. Turing Pi V2 specifications: SoM interface – 4x 260-pin SO-DIMM slot for up to four Raspberry Pi CM4 […]

ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

ClusBerry-2M Industrial IoT controller

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure. But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes. The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement: SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash. Storage – 2x M.2 slots for NVMe SSDs Video Output – 2x HDMI 2.0 ports Connectivity 4x Gigabit Ethernet […]

Software configuration tips for Raspberry Pi clusters & parallel-ssh command


I missed that linux.conf.au 2021 took place on January 23-25 2021, and while browsing the schedule I noticed a talk entitled “Building Raspberry Pi Supercomputers” by Federico Lucifredi, Product Management Director for Ceph Storage at Red Hat. In the talk, he mostly focuses on the software part, and besides some basic steps, I learned about some new commands that be useful to people managing clusters of Raspberry Pi or other Linux boards or hosts. Configuring a cluster He used Picocluster image in his example, but for people wanting to use 64-bit OS, he recommends Ubuntu or Fedora images until Raspberry Pi OS 64-bit becomes stable. The first part of the configuration is making sure all the main user is the same on all board, disable SSH for root, and configure run levels (X not needed on clusters). Networking is configured with fixed IP addresses for Ethernet, and DHCP for WiFi. […]

ClusBerry 9500-CM4 – A Raspberry Pi CM4 cluster, industrial style

ClusBerry Industrial Raspberry Pi CM4 Cluster

Raspberry Pi cluster boards / solutions pop-up from time to time. But so far, I think we’ve seen only one based on Raspberry Pi CM4 modules with the upcoming Turing Pi 2 mini-ITX cluster board supporting four of those. TECHBASE has now unveiled a different kind of Raspberry Pi CM4 cluster with ClusBerry 9500-CM4 integrating up to eight Raspberry Pi Computer Module 4 in a DIN-Rail housing for industrial applications. ClusBerry 9500-CM4 is designed to be customizable with a choice of Raspberry Pi CM4 based modules and I/O cards: Standard 9500-CM4 cluster module with Compute Module 4 and a selection of configuration that include: I/O Controller with DI, DO, AI, 1-Wire, RS-232/485 and CAN interfaces Communication Gateway with up to 2x Ethernet, serial ports, wireless connectivity: LTE-cat.M1, 4G, 5G, LoRa, ZigBee, Z-Wave, Wireless M-Bus AI Gateway with Coral Edge TPU via PCIe M.2, or up to 4x Coral Edge TPU […]
