They are key components in the Mellanox Linkx series 200gb/s and 400gb/s cables and transceivers. This is a milestone

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

Configure the trunk of the Mellanox SwitchRecently, the company's internal openstack platform has been migrated to connect mellanox and centec switches. The centec switch has no major difference between cli and Cisco. It is mainly because the mellanox switch does not support native vlan When configuring trunk, but port supports hybrid. Openstack [standalone: unkn

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

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

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

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

software infrastructure. This article will discuss SDP on Linux x86 platform. Host AdapterTwo types of host adapters support RDMA: Infiniband adapter and RoCE adapter. The former requires an Infiniband Switch, while the latter requires an Ethernet switch. This example uses the Mellanox RoCE adapter. All commands provided in this article apply to the

, increasing virtual I/O will enable CEE data transfer to play a greater role in support, and will also help virtual I/O detach from the converged host adapter. Many vendors have started or are planning to launch CEE and FCoE products (although there are no local FCOE storage requirements). Manufacturers like JDS Uniphase have introduced FCoE testing equipment (JDS Uniphase recently acquired Finisar's Network Tools Division). FCoE market prosperity may also be one of the reasons for its success.

terms of latency, bandwidth, and coherence. This is what Google and Rackspace are putting OPENCAPI ports on their co-developed POWER9 system, and why Xilinx would add t Hem to their FPGAs, Mellanox to their gb/sec InfiniBand cards, and Micron to their flash and 3D XPoint storage.YXR Note: Since OPENCAPI does not define the PHY layer, other CPU vendors, Arm,amd,intel can also define their own PHY, on which

Unlike the Mellanox monopoly InfiniBand chip, the IEEE 802.3BA chip competition will be more intense, the future price advantage of the product will be very obvious. 40G and 100G Ethernet in th

What the hell is an RDMA? It is believed that most children who do not care about high-performance networks do not know much. But the advent of nvme over fabrics let the storage have to take time to look at this thing, this article will introduce the RDMA I know.RDMA (Remote Direct memory access) is intended to directly access the host's memory at the remote, without the need for host involvement . For example, when both the host and client are equipped with RDMA NICs, the data is transferred di

performance and availability. With Sun's industry-standard hardware and Oracle's intelligent database and storage software, the Exadata appliance delivers superior performance for all database load types, including online transaction processing (OLTP), Data warehousing (DW), and hybrid load consolidation. The Exadata all-in-one implementation is simple and fast, capable of handling the largest and most important database applications, and typically allows these applications to run up to 10 time

This article will briefly introduce the Java Socket Direct protocol (Sockets Direct PROTOCOL,SDP) introduced in the Java 7 SDK, and this new technology is a very exciting breakthrough. If you want to native access to InfiniBand's remote Direct memory access (Sqlremote direct Memory ACCESS,RDMA), SDP enables ultra-high performance computing (Ultra high Performance Computing, UHPC) Community uses Java-generic features and advantages in this uncommon scenario. RDMA provides a protocol for low laten

between different instances, but also can be used for heartbeat and regular communication. If the connection fails, the cluster is reorganized to avoid split-brain. Grid infrastructure restarts one or more nodes. You can configure a separate connection between RAC and grid infrastructure. In this case, you need to configure RAC to use the correct connection. This connection should always be private and should not be disturbed by other networks. RAC users can use two technologies to achieve inte
