Broadcom accelerates VMware with copy-free shared data

Published on June 22, 2026 | Translated from Spanish

Broadcom is developing a technology for VMware that allows data to be shared between virtual machines and the host system without creating intermediate copies. This reduces disk and memory workload, resulting in more agile servers and lower resource consumption. For businesses and users, the promise is clear: more performance with less hardware.

Hypervisor node with multiple virtual machines sharing a single memory pool, glowing data streams flowing directly between VMs and host without intermediate storage copies, disk and RAM load indicators showing reduced activity, streamlined server architecture with fewer hardware components, cinematic technical illustration, cold blue and neon green lighting, photorealistic engineering visualization, motherboard traces glowing with data flow, minimalist datacenter background, sharp focus on shared memory pathways, no text or numbers visible

How direct data exchange works in VMware 🚀

The technique, known as direct shared memory, allows the host and VMs to access the same data block without duplicating it. This eliminates the bottlenecks of traditional virtualization, where each transfer required copies and additional processing. The result is reduced latency and more efficient RAM usage. However, the implementation must manage isolation between systems to prevent information leaks or unauthorized access.

The paradise of shared data (with an eye on the lock) 🔒

Now your virtual machine and host will be able to share data like roommates passing the milk. But be careful, because without a good security door, anyone could dip their spoon in the yogurt. Broadcom promises speed, but system administrators are already sharpening their firewalls. After all, sharing is fine, but not when the neighbor is a malicious script.
