At the same time, it can provide a security architecture tool that makes security settings more convenient and automated.

Hierarchical memory expansion:

The hierarchical memory expansion uses DRAM and slow memory such as SCM, AEP and other different memories according to different strategies. The hierarchical memory planning enables hot data to be executed in the fast DRAM memory area and to switch from cold data to the slow memory area for improvements.

Physical storage efficiency impact. This feature is useful for memory sensitive applications like MySQL database, Spark and other applications. Joint innovation with Tianyi Cloud in the virtual machine scenario. With AEP expansion      media, the business performance is about30% better with the stack attached than with the stack not activated, which improves the cost-effectiveness of the physical storage.

As can be seen from the reports,  Open source teams of   Tianyi    Cloud    and    Huawei   OpenEuler  jointly innovate in the classification of the storage expansion function and have completed an internal prototype verification Tianyi Cloud -virtualisointiskenaarioissa.

The result of this test shows that the memory classification technique significantly improves memory performance. Let’s take a closer look at the storage classification technique.

Bottlenecks in storage technology to keep storage costs down are high. As the processing power of CPUs has evolved, and especially as the cost of the ARM core has decreased, memory has become a major problem that limits the cost and performance of businesses. Reducing storage costs and increasing storage capacity have become an urgent problem that needs to be addressed. Therefore, Tianyi and Huawei OpenEuler introduced a function to expand memory rating.

The hierarchical memory expansion function does not affect the business operation by DRAM and slow storage devices like SCM, AEP, etc. to  create tiered memory with automatic memory scheduling so that hot data can quickly run in DRAM. a memory area that enables cold data to be exchanged for a slow memory area, which increases the storage capacity and ensures the efficient and stable operation of the core business.

This feature is useful for applications that use a lot of memory and are used relatively infrequently. In these scenarios the effects are greater and the benefits greater.

But:

In the virtualization scenario, expanding storage capacity while reducing storage costs and increasing storage overselling rate is a bottleneck for Tianyi Cloud’s business.

In response to this issue, Tianyi Cloud and the Huawei openEuler open source team decided to review storage classification technology in scenarios where virtual enterprise internal use is not common, while trying to increase virtual machine density and maintain stable or slightly degraded business performance at the same time.

Huawei OpenEuler Tianyi

Thanks to a joint innovation, AEP and DDR scenarios were prototyped and validated. In comparison, when the memory expansion feature is not enabled, the Redis performance of the virtual machine in AEP has increased by about 30% and is essentially the same as the Redis performance of the virtual machine in DDR.

At the same time, using DDR with AEP with the same storage capacity reduces storage costs by around 35% compared to the pure DDR scenario, which significantly improves the profitability of storage usage.
