[san-tech][02235] Re: IBTA RDMA over Converged Ethernet (RoCE)

System Fabric Works (Sandiaの Red Skyの InfiniBandに協力) の解説

Soft RoCE
  http://www.systemfabricworks.com/soft_roce.html

によると、

  "The Soft RoCE distribution is available now as a specially
   patched OFED-1.5.1 distribution."

とあり、
Download Soft RoCE OFED Distribution
  http://www.systemfabricworks.com/pub/OFED-1.5.1-rxe.tgz

が指定されています。
  Installation
  Configuration Instructions
が続きます。



OFED Cross Reference
  http://www.systemfabricworks.com/ofed-xr.html
でも
OFED-1.5.1
OFED-1.5.1-rxe (the 1.5.1 release plus Soft RoCE support)
OFED-1.5
と別けています。


System Fabric Worksのプレスリリース：
"System Fabric Works OFED Distribution Supports RDMA over Converged Ethernet (RoCE)"
 April 22, 2010
  http://www.systemfabricworks.com/news201004.html

  "With this technology preview release, SFW now offers a third mechanism
   in its OFED release for supporting RDMA over Ethernet, - 1) Soft RoCE;
   2) RoCE (hardware accelerated chipset directly on Ethernet adapter);
   and 3) iWARP(RDMA over TCP/IP with a hardware offload adapter)."

だから、3機能を使うには OFED-1.5.1-rxe版を使えということ？


OpenFabrics Alliance (OFA)の
  http://www.openfabrics.org/downloads/OFED/ofed-1.5.1/
には -rxe版はありません。

は空ですが、

は日々頑張っています。
※2011/06/13時点では 1.5.3
