 ## Prerequisites
 
 Redis Enterprise Software for Kubernetes supports using Auto Tiering (previously known as Redis on Flash), which extends your node memory to use both RAM and flash storage. SSDs (solid state drives) can store infrequently used (warm) values while your keys and frequently used (hot) values are still stored in RAM. This improves performance and lowers costs for large datasets.

 The operator automatically selects the appropriate implementation based on your Redis version:
 
-- **Redis versions earlier than 8.0:** Auto Tiering
-- **Redis 8.0 and later:** Redis Flex
+- **Versions 7.22.2-22 and earlier:** Auto Tiering
+- **Versions 8.0.2-2 and later:** Redis Flex
 
 Redis Flex differs from Auto Tiering in the following ways:
 
+**Redis Flex (8.0.2-2 and later)**
 
-**Redis Flex (Redis 8.0 and later)**
 - Storage engine: Speedb only
 - RAM management: Automatic. Redis manages RAM allocation internally.
 - Configuration: `rofRamSize` isn't validated with minimum ratio requirements.
 - Redis versions: Redis 8.0 and later
 
-**Auto Tiering (Redis versions earlier than 8.0)**
+**Auto Tiering ( 7.22.2-22 and earlier)**
+
 - Storage engine: RocksDB or Speedb
 - RAM management: Manual. Requires explicit `rofRamSize` configuration.
 - Validation: `rofRamSize` must be at least 10% of `memorySize` and can't exceed `memorySize`.
