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

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 the end is what, to put it simply is to increas

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

vendors, such as AMD's a85x/a75 and Intel's z87/b75 are the chipset codes. It is mainly responsible for controlling non-video card slots such as sound card, Sata device, and I/O interface. It almost determines all functions of the motherboard and is the most important chip in the motherboard. There are a lot of old materials on the Internet, such as the "chipset" entry under Baidu encyclopedia. It also says [it is a general term of "nanqiao" and "beiqiao ], in fact, the North Bridge has been i

alignment. So pay attention to byte sequence conversion. When the powercp processor reads int_ack, the host converts the read operation into a PCI bus to interrupt the response transaction. It is the configuration space of 64 bytes that the PCI device must support. The value range is 0x00-0x3f: Many PCI devices only support 64-byte configuration space. The differences between PCI and PCIe configuration spaces are as follows: PCI/PCI-X and

integration and synergy. Setting standards will enable administrators to trust FCoE and CEE on virtualization and blade servers on the periphery of the data center, and to be able to trust their capabilities in the datacenter core environment. Although the standard has not yet been formally established, but has attracted enough manufacturers and enterprises to bring commercial products to the adopters, is expected 2010 FCoE and CEE will become mainstream products. In addition, most of the stora

FAT Tree Network and network level ClosTo say the fat tree concept, you can start with the architecture of the infiniband[Note 1] switch. The InfiniBand switch is prone to 288 ports (port rate 10g/20g/40g), and its chip is a fat tree to build a high-density port switch. Note The 1:

PCI Express, with four-port gigabit connections providing higher network bandwidth Using a four-port Gigabit server Nic on any server, especially on Intrusion Prevention servers, can demonstrate significant advantages. The four-port PCI Express (PCIe) server Nic can provide four network connections from a single server slot, so that other server slots can be retained for more applications. Multiple Gigabit ports can increase network bandwidth through
