. For a hub without a controller, as the Chinese name says, it is a hub. Then the concept of a bridge is introduced, and the Ethernet bridge becomes a switch, so far, InfiniBand is also taking the same route. It may realize that parallel transmission and high-frequency clock cannot have both sides, so it uses high-frequency Clock and serial mode, just like switching Ethernet, the bus topology is changed to

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,
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
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, Ethernet,

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

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 Native Communication. Otherwise, it cannot be re

I'm going to go down to the two and three layers of the switch.
A two-tier switch is equivalent to dividing an interface into multiple interfaces, just to provide a lot of interfaces; (if the landlord is not a professional person can ignore the following content) theoretically it can be understood that the switch does not split the broadcast domain, but split the

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the corresponding VLAN. This is the most common me
