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

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

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

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
