PCACHE provides a mechanism to use persistent memory (e.g., CXL persistent memory,
|
||
|
|
DAX-enabled devices) as a high-performance cache layer in front of
|
||
|
|
traditional block devices such as SSDs or HDDs.
|
||
|
|
|
||
|
|
PCACHE is implemented as a kernel module that integrates with the block
|
||
|
|
layer and supports direct access (DAX) to persistent memory for low-latency,
|
||
|
|
byte-addressable caching.
|
||
|
|
|
||
|
|
Note: This feature is experimental and should be tested thoroughly
|
||
|
|
before use in production environments.
|
||
|
|
|
||
|
|
If unsure, say 'N'.
