The additional Transparent Page Sharing (TPS) management capabilities that we discussed in our blog post of October 16 have been out for about a month for ESXi 5.1 and ESXi 5.5. The same capabilities for ESXi 5.0 will follow next month.
While the recent ESXi patches do not change any TPS setting, the upcoming ESXi Update/patch releases planned for 2014 and Q1 of 2015 will. As we explained in our previous TPS post, the default setting for inter-VM TPS will be such that TPS among virtual machines will no longer be enabled by default. Customers are advised to review the usage of TPS in their environment (see KB 2091682) and plan accordingly.
Also we would like to take the opportunity to mention that the capability of inter-VM TPS is not removed from ESXi and that it can be re-enabled either system wide or for groups of VMs by using the new salting mechanism (see KB 2091682).
