This boosts IOPS performance and reduces latency, significantly shortening load times and execution. Caching works on both reads and writes, and particularly benefits read-intensive applications. Caching approach is not new to hard drives, and computing in general. Operating systems like Windows and Linux come with native caching software. Read More …

The most optimal way is to use the vmdk disk physically located on the shared storage or locally on the ESXi host and this can be done following some specific configurations to be able to access data between different VMs on the same storage.
