USB2.0 signal speed is faster, rise time is hundreds of picosecond, in order to ensure the signal packet true test, need to choose more than 2GHz oscilloscope and differ

hardware and software combination that provides high-performance data read and write operations. Exadata machine consists of exadata database machine, exadata database server, Exadata Storage server and high-speed network interface. The InfiniBand port can be transferred up to 40gb/seconds.HANAThe Fastis to provide in-memory databases with large memory and to use Columnstore in the in-memory database so that more data can be loaded into memory (Colum

suited to the above optimization types, because FPGA can write a completely different hardware architecture and accelerate at runtime.Low Energy compute node ClusterThe most fascinating thing about deep learning models is their ability to expand. Deep learning technology is often extended across multi-node computing infrastructures, whether it is to discover complex high-level features from data or to improve performance for data center applications. The current solution uses a GPU cluster and

The default network service in Red Hat Enterprise Linux 7 and CentOS 7 is provided by NetworkManager, which is the daemon for dynamic control and configuration of the network, which is used to keep current network devices and connections in working condition while also supporting traditional ifcfg types of Configuration file.NetworkManager can be used for the following types of connections: Ethernet,vlans,bridges,bonds,teams,wi-fi,mobile Boradband (such as mobile 3G) and Ip-over-

cumbersome to save the user's home directory, and does not guarantee the consistency of the data. In fact, the NFS service is set, then the client specifies the user's home directory location, and automatically mounts, you can use the user home directory file on any computer. The problems facing There is not enough storage space to store more capacity.Mount storage directly with NFS, there is a certain risk, there is a single point of failure.Some scenarios do not meet the require

problems, the most important is consistency.Cluster is the logical processing of the same task of the machine collection, can belong to the same computer room, but also belong to different computer room. The concept of distribution can be run in a cluster, and a cluster can be used as a node of the distributed concept.In a word, that is: "Separate work" and "a bunch of people" difference.(3) Answer 3:Distributed: One business splits multiple sub-services, deployed on different serversCluster: T

reduce the logic I/O. Network resource bottlenecks In general, the network interaction between applications and databases requires a lot of resources, so the bottleneck in this environment may not be great. However, in a distributed cluster environment, the network environment between database nodes is often referred to as a system bottleneck. In common scenarios such as MySQL Cluster or Oracle RAC, the advantages and disadvantages of the data exchange network environment between nodes may dire

Article Title: Red Hat Enterprise Edition Linux supports 64-channel servers. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The "64-path" supported by Red Hat Linux Enterprise Edition means 64 "logical processors", which include Xeon servers with 64 single-core processors and 16 dual-core dual-thread (such as IBMX460) and 16 4-core processors that are expec

MySQL disk replication technology-DRBD: advantages and disadvantages comparison, precautions and Best Practices DRBD is the block-level synchronous replication technology implemented by the kernel module. The synchronization level here can be adjusted because DRBD uses the NIC for block replication. If, using Infiniband for transmission can effectively process high concurrency. This is a type of replication storage, which is nothing more like a hot st
