Private Preview: Azure Boost remote storage throughput and network bandwidth enhancements
Azure Boost is a Microsoft Azure system that offloads virtualization tasks—such as networking, storage, and host management—from the hypervisor and host OS to purpose-built hardware and software, freeing CPU resources for customer workloads while enhancing security through physical isolation and hardware root of trust. By reducing maintenance impact and improving scalability, Azure Boost enables faster, more secure, and highly efficient cloud operations for demanding workloads.
Performance enhancements of this latest architecture include up to 20 GBps remote storage throughput, up to 1 M remote storage IOPS, and up to 400 Gbps network bandwidth. These enhancements will be available beginning with the D/E/Fsv7 Intel “Granite Rapids” VMs (in preview). Other new VMs will also begin using this architecture and will provide similar performance capabilities.
