Enhanced instance families include storage-enhanced, network-enhanced, security-enhanced, and memory-enhanced instance families. Enhanced instance families are designed for scenarios that require higher performance and more stable processing capabilities.
Introduction
Storage-enhanced instance families: Compared with instance families of the same generation, storage-enhanced instance families optimize capabilities related to Elastic Block Storage (EBS), such as disk bandwidth and IOPS. Storage-enhanced instance families are more suitable for storage-intensive scenarios.
Network-enhanced instance families: Network-enhanced instance families are optimized for network-intensive scenarios. The network metrics of network-enhanced instance families are significantly higher than the network metrics of general-purpose instance families of the same generation. This ensures that network-enhanced instance families can meet the requirements of various scenarios. Network-enhanced instance families are especially suitable for scenarios that require higher network performance than general-purpose instance families.
Security-enhanced instance families: Data security protection is enhanced by using technologies such as trusted computing and confidential computing.
Memory-enhanced instance families: Compared with memory-optimized instance families (r series), memory-enhanced instance families (re series) offer CPU-to-memory ratios higher than 1:8 and larger memory capacities.

re6p, persistent memory-optimized instance family
For answers to commonly asked questions about persistent memory-optimized instances, see Instance FAQ.
Features:
Introduction:
This instance family uses Intel® OptaneTM persistent memory.
ImportantThe reliability of data stored in persistent memory varies based on the reliability of persistent memory devices and the physical servers to which these devices are attached. Risks of single points of failure exist. 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.
NoteFor 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.
Noteecs.re6p-redis.<nx>large instance types are exclusively provided for Redis applications. Persistent memory on instances of these instance types is used as memory by default and cannot be re-configured as local SSDs. For information about how to deploy a Redis application, see Deploy Redis on persistent memory-optimized instances.
Supported scenarios:
