This topic describes the memory optimized instance families and their instance types.

r6, memory optimized instance family

Features
  • Provides predictable and stable high performance and can reduce virtualization overheads with the use of the X-Dragon architecture
  • I/O optimized
  • Supports enhanced SSDs (ESSDs), standard SSDs, and ultra disks
    Note The maximum performance of cloud disks varies depending on instance families. A single r6 instance can deliver an IOPS of up to 200,000. For higher storage I/O performance, we recommend that you use g5se. For more information, see g5se, storage enhanced instance family.
  • Provides strong storage I/O performance with a large computing capacity
  • Ultra high packet forwarding rate
  • Equipped with 2.5 GHz Intel ® Xeon ® Platinum 8269CY (Cascade Lake) processors, up to 3.2 GHz Turbo Boost
  • Supports enabling or disabling Hyper-Threading
    Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
  • Provides strong network performance with a large computing capacity
  • Supports instance type changes to g6 or c6
  • Suitable for the following 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 analysis and mining, and distributed memory cache
    • Hadoop clusters, Spark clusters, and other memory-intensive enterprise applications
