Configure the NIC Bonding for the RAC Private Network In the installation and deployment process of RAC, it is not just a simple installation. The possible single point of failure (spof) should be considered during the installation process. The most important part is the private network. A private network is a channel for communication between RAC nodes, including network heartbeat information between nodes and data blocks transmitted through Cache fu

2013-08-20 15:39:31 Many servers now come with dual gigabit network ports. Using Nic binding can increase network bandwidth and make corresponding redundancy. Currently, it is used in many scenarios. In the NIC binding mode of the linux operating system, the Linux bonding Driver provides a way to bind multiple network interface devices to a single network interface setting for network load balancing and net

Add the -- configuration as follows: 4. test whether the configuration is successful. 5. Windows single Nic is bound to multiple IP addresses (different network segments! ======================================

Due to business needs, three Linux servers in the foreign data center need to add one physical Nic each. Previously, no Nic operation was performed on the physical server, which is a supplement of experience. Linux system version: ScientificLinux6.5x86 _ 64 Server model: Fujitsu suprimergyrx200s8 New Nic model: IntelI350-T2 Due to business needs, three Linux ser

> This error is reported when you restart the NIC when you use Putty to remotely connect to the linux6.0 system: The following error is reported: The Troubleshooting steps are as follows:: 1: Check whether the system recognizes the corresponding NIC (no eth0 Nic exists ): Based on the displayed information, we can preliminarily determine that the system

(I) Advanced Nic commands ① MiI-tool eth0: view the NIC status ② Ethtool view Nic settings Ethtool-I eth0: view the driver of the NIC Ethtool eth0: view the physical characteristics of the network card Ethtool-s eth0: view the underlying status of the NIC (Ii) IP alias

Enable Nic automaticallyAfter centos 6.x is installed, You need to manually activate the NIC every time you start the system. The following methods can be used to automatically activate the NIC after the system starts.CAT/etc/sysconfig/network-scripts/ifcfg-eth0 Device = "eth0"Hwaddr = "00: 0C: 29: FC: 1c: 72"Nm_controlled = "yes"Onboot = "no" Change onboot to Ye

Recently, the new db server found that the NIC was unstable during the stress test. After the stress test was conducted for just a decade, the SERVER's response became very slow, packets are often lost during PING and SSH connections are also interrupted. At first, I thought the db server was unresponsive due to high concurrency. I can check the CPU, memory, and hard disk I/O, and found that none of them reached a high value, it is even much lower tha

CentOS 6.X NIC (eth0) automatic activation method 1. automatically activate the NICAfter CENTOS 6.x is installed, You need to manually activate the NIC every time you start the system. The following methods can be used to automatically activate the NIC after the system starts. vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0"HWADDR="00:0C:29:FC:1C:72"N

My company's product is a dual-network port. The original program is a self-written TCP/IP protocol stack, because it simply implements the simplest situation of ARP, TCP, and UDP, so sometimes problems may occur on the Internet. Later, LWIP and lightweight TCP/IP protocol stack were transplanted to a single network port product, and the problem was solved to some extent. Therefore, dual network card products also need the LWIP protocol stack. This job falls into my head. I will not repeat the p

Centos6.5 multi-nic configuration redundancy (bond) Why do we suddenly remember to configure this? When I went to the data center for implementation last time, I found that most servers have at least two NICs inserted with network cables to connect to switches, but they may have only one ip address, the redundant Nic must be redundant or load balancing. In the following experiment, we will mainly use vmwa

In the virtual machine, when the RAC configures the public Nic sequence method, when the dual Nic is configured, one is public and the other is private, there is always an error, that is, through ipconfig/all, command to view the order of the network card, always the first private type of IP network segment. Solution: the root cause of this problem is that when the NIC
