The release of vSphere 8 from VMware brings several focused improvements aimed at scalability, hardware flexibility, and security. While many platform limits remain similar to vSphere 7 — because the previous version already pushed hardware support close to its maximum — this update refines key areas that matter in modern enterprise environments.

Performance and Scalability Enhancements

Core limits such as virtual memory size, vCPU allocation per VM, and physical CPU capacity per host remain unchanged. However, one notable upgrade is the increase in vGPU capacity per virtual machine, which has doubled. This makes vSphere 8 more suitable for AI workloads, VDI deployments, and graphics-heavy applications.

Lifecycle management capabilities have also expanded. The Lifecycle Manager can now support environments with up to 1,000 hosts, making it more practical for large-scale data center operations. Cluster density has improved as well, allowing significantly higher virtual machine counts within a single cluster, which benefits service providers and enterprise virtualization teams.

Expanded Hardware Passthrough Support

Another important change is the increase in VMDirectPath I/O devices per host, which has grown from 8 to 32. Administrators can now mix device types such as network adapters and GPUs and attach them through the same PCIe switch or direct connection. This provides greater flexibility when designing high-performance virtual environments that rely on direct hardware access.

Device Virtualization Extensions (DVX)

One of the most impactful architectural updates in vSphere 8 is the introduction of Device Virtualization Extensions (DVX). This new framework and API allow hardware vendors to build integrations that retain virtualization benefits even when devices are passed directly to virtual machines.

Previously, workloads using direct I/O often lost mobility features. With DVX, supported devices can now work alongside core virtualization capabilities such as:

• vMotion
• Distributed Resource Scheduler (DRS)
• High Availability (HA)
• Suspend and resume operations
• Memory and storage snapshots

This represents a major step forward for workloads that require both hardware performance and infrastructure flexibility.

Improved Virtual TPM Security

Security enhancements also extend to virtual Trusted Platform Modules. When cloning a virtual machine, administrators can now choose whether to copy the TPM or replace it with a new instance. Selecting the replacement option ensures the cloned VM receives a completely fresh TPM, preventing access to encryption keys or secrets stored in the original machine.

This change strengthens security in environments where VM cloning is common, such as development labs, cloud platforms, and enterprise automation workflows.
