The primary benefits of using Guest RDMA are: Guest RDMA enables SMB workloads for VMs to gain the same benefits of using RDMA on hosts.Īpplicable traffic types: Guest-based storage You're comfortable managing the DCB network requirements.You already have deployments with RoCE in your datacenter.RoCE uses User Datagram Protocol (UDP), and requires PFC and ETS to provide reliability. You already have deployments that use iWARP.You won't be managing the solution after deployment.You don't manage or are uncomfortable managing your top-of-rack (ToR) switches.You don't have experience managing RDMA networks.IWARP uses Transmission Control Protocol (TCP), and can be optionally enhanced with Priority-based Flow Control (PFC) and Enhanced Transmission Service (ETS).

For information on manual deployment see the SDN GitHub repo. NIC vendorįor more information on deploying RDMA for the host, we highly recommend you use Network ATC. InfiniBand (IB) is not supported with Azure Stack HCI. For more information on using RDMA with guest workloads, see the 'Guest RDMA' section later in this article.Īzure Stack HCI supports RDMA with either the Internet Wide Area RDMA Protocol (iWARP) or RDMA over Converged Ethernet (RoCE) protocol implementations. These host CPU resources can then be used to run additional VMs or containers.Ĭertifications required: Storage (Standard)Īll adapters with Storage (Standard) or Storage (Premium) qualification support host-side RDMA. RDMA enables high-throughput, low-latency networking, using minimal host CPU resources. It allows SMB storage traffic to bypass the operating system for processing. RDMA is a network stack offload to the network adapter.

Enables “bursty” workloads to receive the expected amount of traffic.įor more information on Dynamic VMMQ, see the blog post Synthetic accelerations.

Automatic tuning of network traffic processing to CPU cores, thus enabling VMs to meet and maintain expected throughput.

Optimizes host efficiency by using fewer CPU cores.

It builds upon its predecessors of Virtual Machine Queue (VMQ), Virtual Receive Side Scaling (vRSS), and VMMQ, to provide three primary improvements: Dynamic VMMQ requires the use of Switch Embedded Teaming.Ĭertifications required: Compute (Premium)ĭynamic VMMQ is an intelligent, receive-side technology.

Dynamic Virtual Machine Multi-Queue (Dynamic VMMQ or d.VMMQ)Īll network adapters with the Compute (Premium) qualification support Dynamic VMMQ.

Important network adapter capabilities used by Azure Stack HCI include:

An adapter is using an inbox driver if the DriverProvider property is Microsoft. To identify if your adapter is using an inbox driver, run the following cmdlet.

Inbox drivers are not supported for use with Azure Stack HCI. The highest qualification for any adapter in our ecosystem will contain the Management, Compute Premium, and Storage Premium qualifications.
