Since vSphere 6.5, Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) has been supported. RoCE provides extremely low latency and high throughput communication over an Ethernet network, and allows one VM to access the memory contents of another VM directly, without the involvement of the hosts' CPU. This is usually reserved for network-intensive applications. Like FCoE, it requires a lossless network. RoCE requires hardware support in the form of Host Channel Adapters (HCAs) when VMs communicate across different ESXi hosts. RDMA is built into ESXi, and therefore, HCAs are not required when VMs reside on the same ESXi host. As of vSphere 6.7, only some Linux distributions support RoCE, such as guest operating systems running virtual hardware version 13 or later. The RoCE support in vSphere 6.5 (and later) is named Paravirtual...

Overview of this book
VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads.
This book uses proven infrastructure design principles and applies them to VMware vSphere 6.7 virtual data center design through short and focused recipes on each design aspect. The second edition of this book focused on vSphere 6.0. vSphere features released since then necessitate an updated design guide, which includes recipes for upgrading to 6.7, vCenter HA; operational improvements; cutting-edge, high-performance storage access such as RDMA and Pmem; security features such as encrypted vMotion and VM-level encryption; Proactive HA; HA Orchestrated Restart; Predictive DRS; and more.
By the end of the book, you will be able to achieve enhanced compute, storage, network, and management capabilities for your virtual data center.
