Chelsio now Microsoft Azure Stack Certified
We’re very excited to announce Microsoft Hardware Certifications recently achieved by our Unified Wire adapters for Microsoft Azure Stack, Windows Server 2016 and Windows 10 Client environments.

Chelsio announced that its line of Terminator 6 (T6) and Terminator 5 (T5) iWARP (RDMA/TCP) enabled Unified Wire adapters are Microsoft Azure Stack Certified. Chelsio iWARP RDMA solution enables optimal performance for Azure Stack applications by giving direct access to the data residing on hyper-converged or disaggregated storage, while the CPU reduction enabled by RDMA allows a higher VM ratio per Azure Stack node, unlocking return on investment (ROI) benefits throughout the life of the installation.

Chelsio’s T6 and T5 iWARP (RDMA/TCP) enabled Unified Wire adapters have achieved the following hardware certifications:
  • Certified for Microsoft Windows Server 2016, x64

  • Certified for Microsoft Windows 10 Client family version 1607, x64

  • Certified for Microsoft Windows Server 2012 R2, x64

Chelsio also announced that its line of T6 and T5 Unified Wire adapters have achieved hardware certifications for deploying Microsoft Windows Server based software-defined storage (SDS) with Lenovo and Dell server platforms.

Chelsio iWARP enabled Unified Wire adapters power a range of Windows Server 2016 capabilities including Storage Spaces Direct (S2D) software-defined storage, Storage Replica for disaster recovery, SMB Direct for high performance file access, Network Direct for Windows HPC deployments, hardware offloaded iSCSI initiator for SAN applications, and Nano Server for cloud applications. The Windows 10 Enterprise Client RDMA feature provides I/O-intensive desktop applications, such as Video post-production, Oil/Gas and Computer-Aided Design applications, with high-speed access to Windows Server enabled by SMB Direct networking. As a result, customers using Windows 10 Enterprise for professional applications will see dramatic performance improvements while taking advantage of the ease of use and low cost of ownership of Chelsio iWARP.

Microsoft published:
  • recent blog post on 4-node S2D throughput performance using Chelsio T6 100GbE iWARP RDMA adapters.

  • blog post on 3-node S2D performance using Chelsio T5 40GbE iWARP adapters.

  • blog post on deploying a 3-node S2D/40GbE iWARP configuration using VM Fleet.

  • blog post on a 16-node hyper-converged S2D configuration powered by Chelsio 40GbE iWARP delivering an aggregate of ~5M IOPS!

  • An article on S2D configuration showing no additional ToR Switch configuration needed to use iWARP.

Lenovo published:
  • Storage Spaces Direct Deployment Guide which details set-up and configuration of Lenovo-based Windows Server 2016 Storage Spaces Direct deployments providing full support of Chelsio iWARP adapters.

Dell published: Intel published the following articles on S2D Performance using Chelsio iWARP RDMA adapters: Latest Videos Recent Webinars
Recent Publications
Chelsio added a number of News reports and white papers to its technical library, including:
  • Chelsio published a paper highlighting how iWARP RDMA proves to be a dramatically superior choice vs. RoCEv2 for S2D along performance, ease of use, and ease of deployment dimensions.

  • Chelsio published a paper highlighting 10%+ better IOPs and 40%+ better latency for iWARP relative to RoCEv2.

  • Chelsio and Microsoft published a technical brief demonstrating a 4 node S2D cluster using Chelsio 100GbE iWARP RDMA adapters. It showed an aggregated bandwidth exceeding 83GB/s, each VM realizing more than 1GB/s of throughput with average read latency <1.5ms.

  • Chelsio jointly published a white paper on “Meeting Today’s Data Center Challenges” with HPCWire. This 7-page custom whitepaper covers: TCO advantages of the iWARP standard, how RDMA can speed up your data pipeline without CPU involvement, and distinct benefits.

  • Chelsio and Microsoft published a paper demonstrating 100Gbps line rate throughput and effectively the highest possible IOPs for SMB Direct over Ethernet-based fabrics. With plug-and-play operation, enhanced reliability, higher efficiency and line rate performance, SMB over Chelsio RDMA enabled adapters is an extremely compelling solution for Windows Server 2016 storage networking.

  • Microsoft collaborated with Chelsio and demonstrated Storage Replica (SR) operating over a 50Km fiber loop, in synchronous mode at the Microsoft Ignite conference 2016. The results confirmed iWARP’s native TCP/IP ability to operate beyond a single datacenter environment, to extend the RDMA transport over long distance, and its robustness under SR’s load pattern. Long distance replication was shown to provide near local access performance levels, with low impact on I/O performance and latency.

  • Raid Inc., ClearPointe and Chelsio demonstrated a 4-node hyper-converged Storage Spaces Direct architecture at the Microsoft Ignite conference 2016. Chelsio 40GbE iWARP RDMA-enabled adapters that offload network stack processing from the CPU, provide a proof point that higher performance networking enables faster data communication.

  • Chelsio published a paper showcasing the significant performance benefits of Chelsio iWARP RDMA enabled adapters with Windows 10 Client Enterprise. RDMA NIC utilizes 50% less CPU cycles/byte than a standard NIC, enabling a high-speed access to Windows Server storage.

  • Chelsio published a quick start guide to configure Storage Spaces Direct using iWARP RDMA solution in under 20 minutes with any legacy switch with no special settings or uniform switch requirements in the extended datacenter.

  • Chelsio published a paper demonstrating 5M IOPS Performance with Storage Spaces Direct. This highlights how Storage Spaces Direct, combined with advanced flash-based storage connected by Chelsio’s 40GbE iWARP networking solution, helps users build faster, easy-to- scale and reliable storage for their private cloud deployments.

  • Chelsio published a paper highlighting the misconceptions and the reality of Resilient RoCE and the reasons to choose the mature, robust, scalable and plug-n-play Chelsio iWARP solution.
