InformationPrivate networks can only be used for the preceding purposes and cannot be used for other purposes.Network Protocol:Clusterware: TCP/IPRAC: UDPMulti-nic binding: Linux (bonding), Solaris (link aggregation), and Aix (etherchannel)Oracle recommends that the private network be configured with at least 1 GB of Network1. GB-level Ethernet Card2. InfiniBand (Oracle exadata solution), the Protocol Stack is less than TCP/IP, consumes less CPU reso
resource pool, then, place the newly created storage volume in one of the SSDS (with minimal performance impact ).Storage fabric Management After the storage unit is created, the connection between the workload server and the storage volume is created. Then, the following storage network technologies, such as fc, iscsi, infiniband, and fcoe, provide unified interfaces. Then this framework provides the best zone management and fabric analysis to deter

. now, if you have 10 Gbit/s Ethernet, or DDR (dual data rate) IB (InfiniBand), or a faster network in the future, so the existing NFS protocol can make these high-speed networks run like on 1 GB Ethernet. Around 1991, I was called by a site for technical support. they have two Cray supercomputers connected through HiPPI (high-performance parallel interface, 800 MB), and they are also composed of an FDDI (Optical Fiber Distributed Data Interface, 100
improvements to it. The result is rapid innovation. Red Hat solutions include Red HatLinux, developers and embedded technologies, as well as training, management, and technical support. This open-source innovation is delivered to customers through an Internet platform called Red HatNetwork. Red Hat is headquartered in Raleigh, North Carolina. Red Hat has announced the release of Red Hat Enterprise Linux (RHEL) 4.6, the 6th update to its legacy Red Hat 4.x product line: "RedHat is pleased to an
Hadoop implementation and management software. Tightly bound big data machines include Sun server hardware (18 Linux-based x86 Sun servers with 216 processor cores, GB of memory, and TB of raw hard disk space) and Oracle NoSQL database, open-source distribution of R statistics software, and Oracle Java HotSpot virtual machine copy. The big data machine provides 40 Gb InfiniBand access between multiple nodes for Hadoop deployment, many of which are co
use this network for communication.We recommend that you configure the network in redundancy mode for Oracle to bind two physical NICs. Even if one Nic is broken, the other Nic can still provide services, effectively avoiding single point of failure caused by Nic damage.Data transmitted on the private network includes:Cache fusion data, that is, data blocksLocks resource lock request informationHeartbeat dataSCN InformationPrivate networks can only be used for the preceding purposes and cannot
-InfiniBand. For these network types, NetworkManager can configure their network aliases, IP addresses, static routes, DNS, VPN connections, and many other special parameters. You can use the command line tool nmcli to control NetworkManager. 1. usage of nmcli # Nmcli [OPTIONS] OBJECT {COMMAND | help} You can use the TAB key to complete the command. when you forget the syntax of this command, you only need to press TAB to view the option list.

development of the network, storage is no longer confined to the inside of the computer shell, the network storage is becoming the mainstream in the server field. In the storage device is the most important should be hard disk, the drive to read and write speed, capacity and quality of the pursuit of hard disk technology has undergone several changes. From the interface standard of the motherboard with the ATA (IDE), SATA, SCSI, SAS, FC and InfiniBand

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
