When there is a message for me on LinkedIn, it’s almost always a recruiter or SEO marketer trying to sell me something. So, there was a pleasant surprise the other day when it was a marketing person for a software company with a new take on the Edge, datacenters, and software. That company is NodeWeaver.
Here is a statement of the problem. Most of the software in the world runs outside of clouds or datacenters—it runs at the edge. But the edge is made of small systems deployed in tens of thousands of locations, in stores, inside industrial systems, on top of telecom towers. Places that may have limited connectivity, or be difficult to reach, all sharing the fact that they run critical systems, and if something stops, your users are not getting services, or production lines grind to a halt. What happens if something fails?
Existing solutions require manual interventions by skilled technicians to resolve problems. They are complex and difficult to manage. They are difficult to scale to thousands of locations. What is needed has the flexibility of the cloud, but the ability to run everywhere, even on the smallest devices, and run without requiring user intervention.
That’s the idea behind NodeWeaver—a platform that runs any application and manages the distribution, control, and operation thanks to its intelligent autonomous system. Each system learns from what happens on all the others. It becomes smarter the more it expands and able to do more on its own.
NodeWeaver is a software defined operating platform that installs on the bare metal of nearly any x86 hardware and enables the deployment of highly resilient, agile and scalable compute clusters capable of running multiple virtual machines and container-based workloads, optimized for running workloads at the edge fully autonomously, integrating self-management, self-optimizing, self-healing features that dramatically reduces cost of ownership.
NodeWeaver nano clouds consist of 1 to 25 x86 compatible servers of any manufacturer/configuration, from very small to quite large. Connecting a new server to the nano cloud layer 2 switch automatically adds the server components to the virtual resource pool and relevels all applications across the updated server pool.
NodeWeaver delivers full datacenter infrastructure/functionality, optimized for running workloads at the edge, taking less than 1.3GB of RAM to provide all services, leaving the maximum amount of system resources available for actual workloads. NodeWeaver integrates orchestration, software-defined storage, software-defined networking, multiple hypervisors all managed by the intelligent autonomous system.
Customers who need to manage a large fleet of deployments already have their own monitoring framework in place. NodeWeaver has a full API that allows them to monitor (and manage) their edge systems using their existing monitoring framework. Tools like Ansible, Puppet, Chef, Terraform, and OneFlow Services are for operating system and application automation and management. NodeWeaver fully supports those as well, via a combination of pre-built Marketplace VMs (in the case of Terraform) or built-in services (OneFlow), or simply via API and network connection.
The NodeWeaver marketplace enables users to quickly download complete, pre-configured application stacks [including operating system] and service templates, using any of the software products in the catalog, and deploy them with minimal effort; automatically load balanced across nodes in a highly resilient, agile and scalable compute cluster capable of running multiple virtual machines and container-based workloads.
Industrial control systems used to drive production equipment in factories and plants were installed more than 20 years ago and are now becoming outdated, presenting major business challenges. While this infrastructure has provided a stable platform for control systems for many years, it lacks flexibility, requires costly manual maintenance, and does not easily allow process information to be exported and analyzed. Virtualization overcomes the limitations of legacy control systems infrastructure and provides the foundation for the Industrial Internet of Things (IIoT).
Control functions that were previously deployed across the network as dedicated hardware appliances can be virtualized and consolidated onto commercial off-the-shelf (COTS) servers, which not only leverages the most advanced silicon technology but also reduces capital expenditure, lowers operating costs, reduces risk, and improves ability to manage change and implement continuous improvement.
One of the leading providers of solutions for large-scale industrial laundry systems has been a NodeWeaver customer for over 2 years. They control and monitor all processes, provide predictive analytics, as well as automated deployment and management of all systems.
With no IT staff at these locations, system resiliency and the ability to autonomically address failures and maintain uptime is crucial. Additionally, the environments in these locations are characterized by high temperatures and humidity, thus requiring fanless, ruggedized hardware that can withstand these conditions.
NodeWeaver’s software-only approach provided the flexibility to choose the hardware necessary for the application, and its lightweight codebase enables it to run on smaller devices that competing solutions simply can’t support, equating to an unmatched combination of reliability, flexibility, and time to value.
Compute platforms are achieving incredible power in very small form factors. I’ve been contemplating where we could go with industrial applications built on Raspberry Pi. Then I saw this note from Hilscher. This is the world where that company plays. Here is a complete industrial communications application on the new M.2 format for PCI Express that adds real-time communications to PC-based systems.
In just a few minutes, you can connect PC-based devices, such IPCs, HMIs and robotics, to Real-Time Ethernet and Fieldbus networks. The comprehensive package has all necessary hardware and software components, including protocol stacks, device drivers and network connectors. The M.2 card can be simply installed in new and existing devices to connect with industrial automation networks on the fly.
PCI Express M.2, briefly named M.2, is smaller than the Mini PCI Express format and was designed for very thin computing platforms like notebooks and tablets. Since its introduction, automation manufacturers of PC-based systems, such as Industrial PCs, vision systems, robotics, and human machine interfaces (HMIs), have integrated M.2 sockets into their devices for one simple reason. The tiny M.2 format allows many add-in functions to be included into their systems in very tight spaces. Now, with this Hilscher offering, M.2 cards can provide real-time automation network connectivity.
M.2 formats come in various widths, lengths, and socket keys. For this first M.2 card release, Hilscher is using the A+E key socket arrangement, as that is the PCI Express specification’s generic form factor for connectivity add-ins, such as WiFi and Bluetooth. The M.2 2230 Key A+E card, with Hilscher product name CIFX M223090AE, is part of Hilscher’s cifX family of PC Cards. cifX PC Cards are intended for easy integration of a network interface and fast time-to-market of the manufacturers’ products and features.
At the heart of the M.2 2230 card is Hilscher’s netX 90 multiprotocol communication chip. M.2 card users can choose among loadable firmware for PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave and OpenModbus/TCP. Available in Q4 2020 is firmware for CC-Link IE Field Basic and Ethernet POWERLINK Slave. The appropriate network connector is included with delivery. There are adapters available from third-party vendors for other key formats, if required by the application. Additional firmware options, more card and key formats, and OPC UA and MQTT functionality will be released in the future.
Other benefits of the netX 90 ASIC include its small size, low power draw, reduced heat waste and extended temperature range. These features make CIFX M223090AE the smallest multiprotocol card in the market, at 22 mm X 30 mm, and allow it to operate in conditions from -20 deg C to +70 deg C. With its low power consumption, the M.2 2230 is ideal for energy saving applications.
Choosing the Hilscher M.2 card allows users to future-proof their designs. Hilscher continuously provides new firmware for Real-Time Ethernet, traditional Fieldbus and IIoT protocols. Besides a wide range of industrial protocols, Hilscher also provides device drivers for all major operating systems used in the industrial environment, including Windows, Linux, INtime, RTX, and QNX, as well as a C Toolkit for custom device drivers.
