Support for New Architectures:
Expanded support for the latest x86 chip sets, devices, drivers and guest operating systems.
Increased configuration maximums: Virtual machines will support up to 128 virtual CPUs (vCPUs) and 4TB virtual RAM (vRAM). Hosts will support up to 480 CPU and 12TB of RAM, 1,024 virtual machines per host, and 64 nodes per cluster.
Multi-Processor Fault Tolerance:
Expanded support for software-based fault tolerance for workloads with up to 4 virtual CPUs.
Perform non-disruptive live migration of workloads across virtual switches and vCenter Servers and over distances of up to 100ms RTT. The astonishing 10x increase in RTT offered in long-distance vMotion now makes it possible for data centers physically located in New York and London to migrate live workloads between one another.
