Transparent Page Sharing
Transparent Page Sharing (TPS) is a memory saving technology used by vSphere, which allows duplicate memory pages to be shared between virtual machines. To address security concerns with sharing memory between virtual machines across security domains, TPS can be disabled, enabled across groups of virtual machines with the same salt setting, or enabled across all virtual machines in the environment.
How to do it…
Identify the different options to share duplicate memory pages within a virtual machine and across groups of virtual machines.
Configure TPS to meet the requirements for security and the performance of the environment.
Configure salt values on virtual machines to enable or disable page sharing between virtual machines.
How it works…
TPS deduplicates pages of memory, both within a virtual machine, Intra-VM, and across virtual machines, Inter-VM. By default, Inter-VM TPS is disabled due to security concerns on sharing memory pages between virtual machines that cross...
