In-Memory Reach Caching

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

In-memory read caching accounts for 1/16 of node memory, which the virtual machine cannot use. You may disable it and change to cache size.

Precautions

None.

Prerequisites

None.

Steps

  1. Go to Storage > Virtual Storage > Virtual Datastores and select Advanced.

  1. Go to In-Memory Read Caching and click Settings. And can choose whether this function takes effect for all IO block sizes or specific block sizes only.

• In high-performance database scenarios, it is recommended to configure higher memory at a ratio of 1/4 of the node.

• For common scenarios, the memory is allocated in a ratio of 1/16 or 1/8.

• In scenarios where performance requirements are not high but multiple virtual machines are required to run, it is recommended to turn off memory performance optimization.
