For answers to commonly asked questions about persistent memory-optimized instances, see Instance FAQ.

Features:

  • This instance family uses Intel® OptaneTM persistent memory.

    Important

    The reliability of data stored in persistent memory depends on the reliability of persistent memory devices and the physical servers to which these devices are attached. This increases the risks of single points of failure (SPOFs). To ensure the reliability of application data, we recommend that you implement data redundancy at the application layer and use cloud disks for long-term data storage.

  • This instance family allows persistent memory to be used as memory or as local SSDs on instances of some instance types.

    Note

    For more information, see Configure the usage mode of persistent memory.

  • This instance family provides the ecs.re6p-redis.<nx>large instance types for Redis applications.

r6e, memory-optimized instance family with enhanced performance

Features:

  • This instance family offloads a large number of virtualization features to dedicated hardware with the use of the third-generation SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads. This instance family utilizes fast path acceleration on chips to improve storage performance, network performance, and computing stability by an order of magnitude.

  • Compute:

    • Offers a CPU-to-memory ratio of 1:8.

    • Uses 2.5 GHz Intel® Xeon® Platinum 8269CY (Cascade Lake) processors that deliver a turbo frequency of 3.2 GHz to provide consistent computing performance.

    • Allows you to enable or disable Hyper-Threading.

      Note

      By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.

  • Storage:

    • Is an instance family in which all instances are I/O optimized.

    • ESSDs and ESSD AutoPL disks are supported.

    • Provides high network and storage I/O performance based on large computing capacity.

      Note

      For more information about the storage I/O performance of the next-generation enterprise-level instance families, see Storage I/O performance.

  • Network:

    • Supports IPv6.

    • Provides ultra-high packet forwarding rates.

      Note

      Network performance varies based on instance families. For higher concurrent connection and network packet forwarding capabilities, we recommend that you use g7ne.

  • Supported scenarios:

    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding

    • High-performance databases and in-memory databases

    • Data analytics, data mining, and distributed memory caching

    • Enterprise-level memory-intensive applications such as Hadoop clusters and Spark clusters
