The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

A Cisco UCS network adapter can be installed to provide options for I/O consolidation and virtualization support. This guide contains configuration details on RDMA over Converged Ethernet version 2 (RoCEv2) and Single Root I/O Virtualization (SR-IOV).
RDMA over Converged Ethernet version 2 (RoCEv2) is a network protocol that allows for Remote Direct Memory Access (RDMA) over Ethernet networks. It enables low-latency and high-bandwidth communication between servers or storage systems by leveraging the benefits of RDMA technology. RoCEv2 eliminates the need for traditional TCP/IP networking stack overhead, resulting in improved performance and reduced latency. It allows for efficient data transfers and enables applications to directly access remote memory, enhancing overall network efficiency and scalability. RoCEv2 is often used in data centers and high-performance computing environments to optimize network performance and accelerate data-intensive workloads.
RoCE v2 is supported on Windows, Linux, and ESXi platforms.
Single Root I/O Virtualization (SR-IOV) allows multiple VMs running a variety of Linux guest operating systems to share a single PCIe network adapter within a host server. SR-IOV allows a VM to move data directly to and from the vNIC, bypassing the hypervisor for increased network throughput and lower server CPU overhead.
