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 the PCI bus is too slow, and its parallel desig

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,

Since ancient times there have been no beginning to the end of the kind of wonderful, I call it a martyr.InfiniBand is one of them, and although it has a falling trend, I still have to applaud it.If Ethernet is designed to connect the host, then InfiniBand's original intention is to dismember it, the genetic difference, destined for them to launch a war, of course, this is something.Server is powerful, but the PCI bus is too slow, and its parallelization design is not suitable for high-speed env

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,

Hari subramoni, Gregory Marsh, sundeep narravula, Ping Lai, and dhabaleswar K. 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

In the early SAN storage system, the data transfer between the server and the switch was done through optical fiber, because the server was transferring the SCSI instruction to the storage device, could not take the IP protocol of the ordinary LAN network, so it needed to use FC transport, so this SAN is called Fc-san, And later appeared with the IP protocol encapsulated SAN, can completely walk the ordinary LAN network, so called Ip-san, which is the most typical of the now popular iSCSI. Both

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

1, first introduce what is the HBA. Here the HBA, the full name FC HBA, that is, fibre Channel Host bus Adapter. In a FC network, a host (such as a server) needs to connect to a FC network, FC storage device (such as a SAN), using an interface card, just as Ethernet cards are required to connect to Ethernet. This interface card is called FC

In Solaris, how to configure the fc hba to an Ethernet Card IPFC can easily set a fc hba to an Ethernet card, which is of great significance. In some work sites, if you need to copy a large amount of data through the network, you will often find that the speed of the Gigabit Nic is insufficient, and network aggregation cannot compensate for bandwidth insufficiency, at this time, you can make full use of the

Host Bus Adapter-Host Bus Adapter (HBA) is a Host Bus Adapter that provides input/output (I/O) between servers and storage devices) A circuit board and/or integrated circuit adapter that processes and physically connects. Because the HBA reduces the burden on the master processor in data storage and retrieval tasks, it can improve server performance. An hba and t

The solutions are:1. Use MS Utility "Fcinfo.exe" (Fibre Channel information Tool (fcinfo)) to view the WWN number of the HBA card.The Fcinfo tool is installed on a Windows system that needs to view the WWN number, and then, in the Start menu, type "CMD" in "Run" and enter command-line mode, and you can see the WWN number of the host HBA by entering Fcinfo.2, after searching, find article finds

first released, there was a lot of skepticism, because it was the only way the IT environment needed a new transmission and protocol. Now there are two more sophisticated networks, Fibre Channel SAN storage and Ethernet LAN storage. In addition, although InfiniBand has recently gained widespread attention, it does not look like a universal way of transmitting data for LAN and SAN instead of Ethernet.
