the device is interoperable. Core-level Fibre switch The core-level switches, also called guides, are typically located in the center of a large san, making several edge switches interconnected to form a SAN network with hundreds of ports. The core switch can also be used as a separate switch or edge switch, but its enhanced functionality and internal structure make it work better in the core storage environment. Other features of the core switch include supporting protocols other than optica

Can be synchronized using SG_IO IOCTL, or the target is a SG character device, we use read and write to perform asynchronous IO Null does not transmit any data, just disguised as such. It is mainly used for training the use of FIO, or for basic debug/test purposes. NET transmits data ove

cachefusion mechanism. Therefore, to improve the performance of RAC can start from two aspects, on the one hand, improve the ability of cache fusion, this can be through better interconnection equipment, such as the G-class private network, or the use of InfiniBand and other DRA technology; Can minimize the cache fusion flow, reduce the interdependence between the instances. and service is the latter kind of thinking on the basis of development.

Ethernet transmission, was approved in March 2004, but the transmission distance is limited to 15 meters. The 10gbase-cx4 uses the Xaui (Gigabit add-on interface) defined in 802.3ae and the 4X connector in the InfiniBand, which is referred to as the "CX4 copper cable" (in fact, a shielded twisted pair). Instead of transmitting gigabit data using a single copper link, the 10GBASE-CX4 specification uses 4 transmitters and 4 receivers to transmit the gi

replication (concurrent replication) with virtually no latency; More than one can read and write nodes, can achieve write extension, but preferably in advance to the sub-database table, let each node write different tables or libraries, to avoid galera to resolve data conflicts; The new node can be deployed automatically, the deployment operation is simple; Strict data consistency, especially suitable for e-commerce applications; fully compatible with MySQL; While there ar

The default network services in Red Hat Enterprise Linux 7 and CentOS 7 are provided by the NetworkManager, a daemon that dynamically controls and configures the network to keep the current network devices and connections working, while also supporting the traditional ifcfg type 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-i
