infiniband vs ethernet

Crying for InfiniBand, InfiniBandSince ancient times, there have been some wonderful things that have not ended before. I call them martyrs.InfiniBand is one of them. Although it has fallen, I still want to applaud it.If the purpose of Ethernet is to link hosts together, InfiniBand's original intention is to dismember them. The difference between these genes is doomed to a war.The server is powerful, but th

InfiniBand now plays a key role in high-speed network architecture technology. By aggregating computing nodes in a computer cluster to accelerate computing performance, InfiniBand has made great strides in the field of high-performance computing. Although the InfiniBand Network performs better in terms of high bandwidth, low latency, and overall cost efficiency,

The explanation is as follows: Multi-rail support (multiple ports per adapter and multiple adapters) It looks a bit like multi-nic binding or multi-port binding on a single InfiniBand Nic. But this is not the case. Of course, binding multiple NICs or multiple ports will increase the bandwidth, but the multi-rail here is not that simple. In fact, the term "Multi-Rail" is not limited to InfiniBand,

The InfiniBand Device of silverstorm supports two communication protocols: IB native. During mpich compilation, device = Vapi is specified during configure; one method is IP over Ib. During mpich compilation, device is Ethernet, because the above processes IP and TCP. Therefore, it is clear that the performance of InfiniBand can only be achieved through IB Nat

Who used infiniband in linux? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Currently, the computing center I am using is redhat ws3.0 LINUX and is equipped with 10 Gb infiniband, however, it is depressing that no one has been using infiniband for a long time, leading to the current failure of

PandaDepartment of Computer Science and Engineering, the Ohio State University InfiniBand is a new network transmission technology in recent years. It features high bandwidth and low latency. A unified interconnection structure is formed through a persistent cable connection mode, which can process storage I/O, network I/O, and inter-process communication (IPC ). I

Ethernet transmission, was approved in March 2004, but the transmission distance is limited to 15 meters. The 10gbase-cx4 uses the Xaui (Gigabit add-on interface) defined in 802.3ae and the 4X connector in the InfiniBand, which is referred to as the "CX4 copper cable" (in fact, a shielded twisted pair). Instead of transmitting gigabit data using a single copper link, the 10GBASE-CX4 specification uses 4 tr

In the previous article we introduced the Ethernet 5 layer model, which I want to learn about the encapsulation and unpacking of Ethernet data, and how Ethernet data is transmitted. First, data encapsulation when our application uses TCP to transmit data, the data is fed into the protocol stack, then passes through each layer one by one, knowing that the final to

Http://blog.csdn.net/sailor_8318/article/details/3907345 Differences between switched Ethernet and shared Ethernet A hub, also known as a hub, belongs to the data link layer in the OSI model. However, as the hub is a shared-bandwidth device, the efficiency of the hub becomes very low in the heavy network and is prone to broadcast storms. Therefore, we cannot see hubs in medium and large networks. A vswi

Reducing energy consumption is the next goal of information and communication technology managers in order to spend less money and work more, energy-efficient Ethernet can save energy and reduce operating costs. This new standard network, in most cases, au

Consider the fiber channel for storage, Infiniband or Myrinet Technology for applications for high-performance computing and cluster applications. The low cost and flexibility of Ethernet are driving this trend. The study at the University of California, Santiago, is a good example of how far this idea can go. Vahdat
