Reading Time: < 1 minute Note: VMware has removed the vRAM Entitlements concept and restriction. So this post is no more relevent! Introduced during the official announce of vSphere 5, this news in the vSphere licensing (expecially for the hosts) has been changed (the first rumor of this was mentioned here by Gabrie van Zanten).

Reading Time: < 1 minute In vSphere 5, for the first time, ESXi has now an integrated firewall. In this way another feature gap between ESXi and ESX has been filled.
