As revealed by the reports, Tianyi Cloud and Huawei OpenEuler open-source teams have jointly innovated the memory grading expansion feature and conducted internal prototype verification in Tianyi Cloud virtualization scenarios.
The result of this test shows that memory grading technology greatly improves memory cost performance. Let’s take a look at the memory grading technology in a bit of detail.
Constrained by the bottleneck of memory technology, memory costs are high. With the development of CPU computing power, especially the reduction of ARM core costs, memory has become a key issue that constrains business costs and performance. How to save memory cost and expand memory capacity has become an urgent problem to be solved. Therefore, Tianyi and Huawei OpenEuler introduced the memory grading expansion function.
The memory hierarchical expansion function does not affect business functions, through DRAM and low-speed memory media, such as SCM, AEP, etc. to form multi-level memory, through automatic memory scheduling to make hot data run in the DRAM high-speed memory area, allowing cold data to be exchanged to low-speed Memory area, thereby increasing the memory capacity and ensuring the efficient and stable operation of the core business.
This feature is suitable for applications that use a large amount of memory and are relatively infrequently used. In these scenarios, the effect is better and the benefits are greater.
In the virtualization scenario, how to expand the memory capacity while reducing the memory cost and increasing the memory oversold ratio is a business pain point facing Tianyi Cloud.
In response to this pain point, Tianyi Cloud and Huawei’s openEuler open source team decided to verify the memory grading technology in scenarios where virtual machine internal business access is not frequent, and try to increase virtual machine density while keeping business performance flat or slightly degraded.
Through joint innovation, the AEP and DDR scenario were prototyped and verified. Compared with when the memory expansion function is not enabled, the redis performance of the virtual machine in AEP has increased by about 30%, basically reaching the same level as the performance of the virtual machine redis in DDR.
At the same time, when the memory capacity is equal, the use of DDR with AEP reduces the memory cost by about 35% compared to the pure DDR scenario, which significantly improves the cost-effectiveness of memory usage.
Huawei Euler operating system exceeds 2.45 million installations
Today, at the 2022 Full Connect Conference, Huawei informed that Euler operating system excelled with a huge number of installations. To date, Euler is actively running 2.45 million products and has offered efficient performance.
Huawei has been serving in the 2022 Full Connect Conference. The event was held from November 7 to November 9. Ultimately, the company unveiled several concepts of HarmonyOS, Kunpeng, Ascend AI, and the Euler system.
While describing technical factors, Huawei’s Executive Director and the ICT Infrastructure Business Management Committee Director – Wang Tao revealed that Huawei Euler has exceeded 2.45 million installations till now.
Significantly, Euler has managed the difficult steps of ecological growth. As of now, it will more productive and reliant in terms of providing services and durable functioning. On the other hand, HarmonyOS has also surpassed 320 million installations.
This is a huge achievement and developers are looking forward to some new tweaks and pinches in the Euler system. However, Huawei hasn’t uttered any word on this matter.
openEuler innovative version
Just like OpenHarmony, Huawei’s openEuler system is an open-source Linux distribution surface. The operating system provides a huge platform for global developers to develop and create innovative software and applications.
In October this year, the new openEuler 22.09 version was released with several thoughtful features. Besides, it also holds finer interconnection capabilities between HarmonyOS and Euler systems. It optimizes the kernel elements and revamps the geographic inspections.
As a result, user experiences better integration and facilities between both systems. Notably, the 22.09 openEuler build includes the participation of 1,265 developers. Further, it has 670 million existing code lines and 20.12 million new code lines.
Four key factors to digital infrastructure
Additionally, Wang Tao described the four aspects that contribute to digital evolution. These are network architecture, strong computing power, a diversified software ecosystem, and an open digital surface.
Eventually, these measures will bring new opportunities for digitalization.
OpenEuler 22.09 based NestOS Cloud system is released
After the new openEuler 22.09 version, the Euler community has released the NestOS Cloud system. The respective cloud base is the result of the effective efforts of Kylin Software and the experts of the Euler open source community.
Let’s understand what is NestOS, and how it is beneficial for the developers.
NestOS is a cloud operating system, based on the openEuler 22.09 version. In November last year, the EulerOS open source community brought this program into existence. It’s a cloud base system that provides the best container host, and safety features to run related tasks on a large scale.
In the latest development, the community has released the NestOS version of openEuler 22.09 with some enhanced features. This time, the new addition is the nestos-assembler container image, optimized K8S, and an improved OpenStack system.
Together, these components will help in providing a new installation experience to the developers and users. Alongside, the respective cloud system also showcases the dual-root file system, and atomic update to quickly integrate and build up the tasks.
As stated, this is the new version of NestOS based on the openEuler 22.09 version. Hence, some fresh and unique features are taking place in this system. Let’s read about them one by one.
It is a container image tool for building NestOS programs. It uses a few scripts, rpm packages, and tools required in the entire process of NestOS build-up. Currently, the nestOS-assembler released to OEPKG, and the kola component in this assembler supports the NestOS qcow2 and iso images for testing.
NestOS system usually associates with mainstream engines. For instance, iSulad, Docker, and Podman. Further, it can simplify the containerized workloads. The Cloud Base system has the function to begin the work from the same place. Thus, it saves the ignition file to configure the system and access the management.
NestOS Deployment of K8S
So far, Kubernetes introduced a command line system to simplify the installation process and for solving the availability problem. However, using the command line needs several steps and a lot of effort with extreme carefulness.
To eliminate these complicated methods, NestOS deployed the K8S system. It easily supports custom integration of binaries. For instance, kubeadm, kubelet, kubectl, and other packages. Moreover, you can complete the placement of various resources while installing the NestOS with the help of the K8S system.
You might have heard this term earlier as well. OpenStack is a cloud management project consisting of several essentials. For instance, Nova, Keystone, Glance, Swift, Cinder, etc. It offers firmware to develop and operate public clouds, private clouds, and other virtual mechanisms.
With this feature, it is convenient to manage an immutable framework and update the file configuration. The NestOS 22.09-LTS-SP1 is in the development phase. Interested developers can attend the sig-CloudNative and sig-K8sDistro.
New OpenEuler 22.09 version support better features between Euler and HarmonyOS
OpenEuler Community has officially developed and released the OpenEuler 22.09 version with some immersive features for the Euler and HarmonyOS system. Besides, it also brings expansion of computing power and some other high-end functions.
According to the new reports, the OpenEuler 22.09 build adds revamped system images for SW-64 and LoongArch architecture. Further, it supports ARM architecture memory fault tolerance enhancement, SME, and commercial secret acceleration. The latest version also holds Intel SPR kernel and visualization functions.
