Chelsio delivers 40GbE iWARP RDMA for Windows Server 2012

New Update

SUNNYVALE, USA: Chelsio Communications, a leading provider of high performance Ethernet solutions, announced the release of its Windows Server 2012 NDK driver for RDMA enabled SMB Direct.


Chelsio's high performance storage adapters enable a converged interconnect solution that simultaneously supports a complete suite of networking and storage protocols, as well as Windows Server 2012 Hyper-V for virtualized applications.

Chelsio's Ethernet adapters are the only ones capable of true 40Gb line rate operation at 8KB I/O with Windows 2012 SMB-Direct. Chelsio demonstrated 40Gb operation of the Windows Server 2012 SMB Direct protocol using a Chelsio T5-based iWARP RDMA over Ethernet adapter at the Storage Developer Conference in Santa Clara, CA. The demonstration showed line rate throughput at 8KB I/O size, effectively the highest possible IOPS for SMB Direct over Ethernet-based fabrics.

"Windows Server 2012 provides breakthrough innovations in storage technology," said Jose Barreto, principal program manager, File Server Foundation, Microsoft. "When combined with high performance RDMA adapters such as the ones from Chelsio, Windows 2012 enables robust and high performance Flash based storage appliances."

"Chelsio's 40Gb iWARP RDMA solution offers a new level of performance and scalability for Windows cloud installations," said Kianoosh Naghshineh, president and CEO of Chelsio. "The offload capability of the adapters enables the deployment of less expensive and power efficient CPUs on the server side, resulting in a more economical and greener virtualized cloud infrastructure. With the combined support for offloaded Network Direct, iSCSI and FCoE, T5 adapters provide the most complete Windows solution, releasing the full value of a Windows platform."
