Detailed Description

The Intel® Dynamic Load Balancer (Intel® DLB) is a PCIe device that provides load balanced, prioritized scheduling of events across CPU cores enabling efficient core-to-core communication. It is a hardware accelerator located inside the latest Intel® Xeon® devices offered by Intel. This software enables Intel® DLB acceleration on VMware ESXi* hypervisor throughout Intel® Scalable I/O Virtualization (Intel® Scalable IOV) supported along with VMware Enhanced DirectPath I/O (Enhanced Drivers) and Single Root I/O Virtualization (SR-IOV) supported along with VMware DirectPath I/O (non-Enhanced Drivers). A combination of Intel and VMware technologies enables the creation of Virtual Devices from a single Intel DLB Physical Device to support hardware acceleration for multiple guest Virtual Machines (VMs).
