→VMware Server Virtual Disk Caching Options
The disk write caching policy for virtual disks defines the point at which new data is written to the virtual disk (as opposed to being cached in memory before being written) by the guest operating system. These settings have implications for performance, with increased performance being available at the cost of data integrity. A choice of two policy options are available:
* '''Optimize for safety ''' - Data is not cached. Write operations made by the guest operating system are written immediately to the virtual disk image. Reduces risk of data loss in the event of a system failure, but results in slower disk write performance.
* '''Optimize for performance ''' - Write operations performed by the guest operating system are initially cached prior to being written to the virtual disk. Provides increased write performance at the cost of increased risk of data loss on system failure.
