Preview: The storage-optimized Z3 machine series offers a bare metal (-metal) machine type with 192 vCPUs

## Feature **Preview**: The storage-optimized Z3 machine series offers a bare metal (`-metal`) machine type with 192 vCPUs. Bare metal instances let you create an instance with direct access to the machine's CPU and memory, without a virtualization layer in the middle. To learn more, see [Z3 machine series](https://cloud.google.com/compute/docs/storage-optimized-machines#z3%5Fseries). For information about bare metal instances, including regional availability, see [Bare metal instances on Compute Engine](https://cloud.google.com/compute/docs/instances/bare-metal-instances).
