Compared to vSphere 7, the new vSphere 8 brings notable scalability improvements, although many features remain unchanged, as vSphere 7 had already optimized the platform’s capabilities. For instance, the limits for vMem, vCPU per VM, and pCPU per host remain the same. However, the vGPU per VM has doubled, and the lifecycle manager now supports up to 1,000 hosts. Additionally, the maximum number of VMs per cluster has increased to 10,000. Another enhancement is the increase in VMDirectPath I/O devices per host, from 8 to 32, allowing for a combination of NIC and GPU devices that can share a PCIe switch or direct connection. vSphere 8 also introduces new Device Virtualization Plugins (DVX).
In earlier versions of vSphere, virtual machines using direct I/O paths to physical hardware were restricted in their mobility. DVX introduces a new API and framework that enables vendors to create hardware virtual appliances with support for features like vMotion, DRS, HA, and suspend/resume. It also offers disk and memory snapshot capabilities. One issue with TPM and virtual machine emulation is the potential security risk. To address this, VMware has introduced a feature that allows users to choose whether to copy or replace the TPM device. When cloning a VM, selecting the “Replace” option creates a new TPM device, ensuring that the new VM does not have access to the source VM’s secrets.
