re6p, persistent memory-optimized instance family

For information about frequently asked questions about persistent memory-optimized instances, see Instance FAQ.

Features
  • Uses Intel® OptaneTM persistent memory.
    Notice 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 may cause risks of single points of failure. 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.
  • 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.
  • Exclusively provides the ecs.re6p-redis.<nx>large instances types for Redis applications.
    Note ecs.re6p-redis.<nx>large instance types are exclusively provided for Redis applications. The persistent memory on instances of these instance types is used as memory by default and cannot be re-configured as local SSDs. For more information about how to deploy an Redis application, see Deploy Redis applications on re6p instances.

  • Compute:
    • Offers a CPU-to-memory ratio of 1:8.
    • Uses 2.5 GHz Intel® Xeon® Platinum 8163 (Skylake) or Intel® Xeon® Platinum 8269CY (Cascade Lake) processors for consistent computing performance.
  • Storage:
    • Is an instance family in which all instances are I/O optimized.
    • Supports ESSDs, standard SSDs, and ultra disks.
      Note The maximum performance of disks varies based on instance families. A single instance of this instance family can deliver up to 200,000 IOPS. For higher storage I/O performance, we recommend that you use g6se.
  • Network:
    • Supports IPv6.
    • Provides an ultra-high packet forwarding rate.
    • Provides high network performance based on a large computing capacity.
  • Applicable scenarios:
    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
    • High-performance and in-memory databases
    • Data analysis, data mining, and distributed memory caching
    • Hadoop clusters, Spark clusters, and other memory-intensive enterprise-level applications
