Chelsio And Ryussi Demonstrate End-To-End iWARP RDMA Between Windows 10 Enterprise And MoSMB SMB3 Server

Demonstration Highlights iWARP CPU-Efficiency and Application Acceleration Benefits for Windows 10 Enterprise Media and Entertainment (M&E) Applications

SUNNYVALE, Calif., Feb. 12, 2020 /PRNewswire/ — Chelsio Communications, Inc., a leading provider of high performance (1Gb/10Gb/25Gb/40Gb/50Gb/100Gb) Ethernet Unified Wire adapters and ASICs for storage networking, virtualized enterprise datacenters, cloud service installations, and cluster computing environments, and Ryussi America, Inc, a Storage & Systems Product Development and Consulting company, today announced the results of the performance of Chelsio Terminator 6 (T6) iWARP RDMA adapters with Windows 10 Enterprise Client RDMA feature enabling high-speed access to the Ryussi MoSMB SMB3 server using SMB Direct.  Windows 10 Client, Enterprise edition includes an inbox driver for Chelsio iWARP RDMA enabled 1/10/25/40/50/100 GbE Unified Wire adapters.

The results showcase how Chelsio’s iWARP RDMA enabled NIC delivers ground breaking performance of ~93 Gbps over SMB protocol using SMB Direct-enabled MoSMB Server.  The performance is achieved using standard Ethernet infrastructure.  The results also demonstrate that the combined solution delivers 84 Read FPS and 91 Write FPS for 4K frames for single client, making it well suited for demanding 4K media workflows like rendering, animation, editing, post-production, color correction, VFX or virtual reality.

The digital film is rapidly evolving to 4K and beyond.  As the Media & Entertainment industry moves towards higher resolution and multi-camera mode of production, the need for high performance as well as high capacity storage devices is increasing like never before.  This pressing need for fast and scalable storage is seen across the entire lifecycle of digital content Capture, Creation, Editing, Archiving and Distribution.

SMB Direct, or SMB (Server Message Block) over RDMA (Remote Data Memory Access), is a networking offload technology which makes data transfers between clients and file servers faster and more efficient without involving the host’s CPU.  It achieves this by using techniques such as Zero Copy, Kernel Bypass and CPU Offload.  This results in increased throughput, reduced latency, and the CPU power is freed up for time-critical performance-intensive media workloads like studio editing, rendering, post-production and broadcast while working on large unstructured datasets.

“Chelsio is pleased to collaborate with Ryussi to demonstrate high-performance 1/10/25/40/50/100 GbE iWARP Ethernet RDMA solutions for Windows 10 Enterprise M&E deployments,” said Kianoosh Naghshineh, CEO, Chelsio Communications.  “Chelsio iWARP RDMA offering can now enable the full benefits of RDMA networking to be delivered for large-scale, end-to-end Windows 10 workstation to MoSMB Server 4K media applications via using the same high-performance wire protocol on both ends of the wire.”

“The data intensive nature of M&E workflows propelled by higher resolutions and faster frame rates is driving an explosive growth of collaborative, high performance storage solutions,” said Sandeep Bhambani, CEO of Ryussi.  He adds, “Ryussi is happy to team up with Chelsio and Microsoft to showcase a powerful solution for today’s demanding 4K and higher M&E workloads.  MoSMB supports RDMA natively and combined with Windows 10 workstation and Chelsio’s 100GbE iWARP RDMA networking solution, makes it the preferred choice of SMB server for high throughput, low latency M&E production and post-production workflows.”

“iWARP enabled SMB Direct is enabling server storage I/O technology to boost productivity for both Windows, as well as Linux based systems,” said Greg Schulz, Sr. Analyst Server StorageIO. “Chelsio, along with Ryussi, have demonstrated how iWARP enabled SMB Direct can boost performance, along with productivity for Media & Entertainment workflows; after all, fast networks need fast protocols and drivers.”

The Power of MoSMB – high performance, high availability SMB 3.0 server on Linux

The MoSMB server stack on linux(Ubuntu, FreeBSD, Solaris) allows admins to achieve high availability, reduce operational costs and migrate virtual machines faster. It can be widely used to provide file services to SMB clients. In addition, MoSMB also has enterprise grade features that help reduce cost for small and midsize businesses by providing storage for hyper-v server virtualization. MoSMB server is not just a file sharing server but with SMB protocol 3.0 features it has SMB Direct, SMB Multichannel (multiple connections per SMB session), SMB Transparent Failover, SMB Scale-Out, SMB Directory Leasing and many more. To name a few advantages of MoSMB, with improved performance of SMB Direct, improved SMB bandwidth management, and enabling Hyper-V live migration of VMs and VM storage without failover clustering can be achieved. Achieving high availability of Hyper-V VMs: One benefit that boosts the return on investments is the use of Mo-SMB file shares as a shared storage for Hyper-V hosts. This is sometimes referred to as “Hyper-V over SMB.” In earlier versions of Hyper-V you had to store Hyper-V VMs on a block-based storage to achieve high availability of the VMs. With MoSMB, you can configure Mo-SMB file shares to host Hyper-V VM files such as VM configuration, virtual hard disks and snapshot files and expect the same reliability, availability and high performance that you achieve using block-based storage. When implemented as a shared storage, MoSMB helps deploy a Hyper-V server virtualization infrastructure without spending precious IT dollars on expensive SAN devices. There are several other Hyper-V scenarios where MoSMB can be a useful. You can create a file server cluster running on linux machines, create SMB shares, configure the available properties for the SMB shares, and then have the SMB shares available for Hyper-V hosts for hosting the VM files. If you deploy VM files over a Mo-SMB share created on unix-like servers (Ubuntu, FreeBSD, Solaris) the SMB Transparent Failover feature can help you provide continuous availability of VMs in case of any maintenance activity for one of the clustered nodes in a file server cluster. This is achievable by implementing MoSMB Scale-Out file server cluster. A MoSMB scale-out file server hosts Mo-SMB shares that are simultaneously online on all the nodes in a file server cluster.

Reducing operational expenditure: You can manage file shares instead of requiring someone with expertise to manage storage fabric and LUNs which, in turn, helps you reduce the operating expenditures associated with managing a SAN environment. A virtual administrator who knows how to manage a file share can easily manage MoSMB shares rather than requiring another administrator to manage the complex SAN environment. MoSMB as a shared storage for VHDX file sharing: The VHDX file sharing feature of Hyper-V helps you implement guest clustering without exposing SAN storage to Hyper-V guests. The VHDX file that will be shared among the multiple VMs must be kept on a shared storage. Some Hyper-V features use SMB: It is worth mentioning that SMB has a role to play for some of the notable Hyper-V features such as Storage Live Migration and Shared Nothing Live Migration introduced in Windows Server 2012. Neither of those features require linux failover clustering to be implemented to utilize the SMB 3.0 capabilities to move VM and its storage while the VM is running. Faster Live Migration of VMs: For Hyper-v live migration of VMs, administrators can select SMB Direct or SMB over RDMA in MoSMB for live migration protocol for transferring VMs to other Hyper-v hosts. RDMA network acceleration will give faster live migration. A protocol for future virtualization: In SMB 3.1.1 protocol, features like SQOS have been added for cloud deployments. This is being supported in MoSMB server stack and will be available to customers by Q2 2017. Reference:
