Summary
4TB (EXCLUDING Reliable Memory Technology)
Details
Maximum amount of addressable physical host memory
vSphere 5.5: 4TB (increased from 2TB with 5.1)
New in vSphere 5.5 Support for Reliable Memory Technology - NOT included with this edition:
The vSphere ESXi Hypervisor runs directly in memory, an memory error can potentially crash it and the virtual machines running on the host. The ESXi Hypervisor can now take advantage of Reliable Memory Technology, a
CPU hardware feature through which a region of memory is reported from the hardware to vSphere ESXi Hypervisor as being more “reliable. This information is then used to optimize the placement of the VMkernel and other critical components such as the initial thread, hostd and the watchdog process and helps guard against memory errors.
