re6p, persistent memory optimized instance family
For answers to commonly 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 increases 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.
- Supports configuring different usage modes of persistent memory on some instance types.
You can use the persistent memory as memory or local SSDs.
Note For more information, see Configure the usage mode of persistent memory.
- Provides the ecs.re6p-redis.<nx>large instances types for Redis applications.
Instance types exclusively for Redis are in invitational preview. To use these instance types, submit a ticket.
Note ecs.re6p-redis.<nx>large instance types are exclusively provided for Redis applications. By default, the persistent memory of the dedicated instance type is used as memory. You cannot re-configure the persistent memory of a dedicated instance type as a local SSD. For more information about how to deploy an Redis application, see Deploy Redis applications on re6p instances. - Uses 2.5 GHz Intel ® Xeon ® Platinum 8269CY (Cascade Lake) processors that deliver a maximum turbo frequency of 3.2 GHz for consistent computing performance.
