First, we will introduce the situation that both server A and server B are CentOS 4.6 systems. Now we need to build an HA Cluster. To avoid split-brain attacks, we need to improve the reliability of the heartbeat link, it is the current connection condition. eth2 and eth3 of server A are connected to eth2 and eth3 of server B respectively (there is no sequential relationship). All NICs are Gigabit NICs, And the topology is shown below:
In this article, we will discuss the hardware situation. Se
Production Environment host server deployment Summary
Deploy all the host servers of a new project with colleagues over the past two days, and record the general process.Environment:Host model: HP ProLiant DL380 Gen9Basic configuration: 2.40 GB memory, 2 E5-2630 7200 GHz CPU, 12 4 tb sata rpm hard driveRAID card: Smart HBA H240ar (supports RAID1, RAID5, RAID50, RAID1 + 0, etc)In the production environment, host servers are deployed. Generally, the fol
Server for HP's DL380 serverFirst, enter the Setup interface1. After the HP startup screen prompts "Press any key to enter ..." then press any key.2, the red word "Smart Array" will be prompted to press "F8" enter. (This is the second F8 hint) However, if there is a problem with the display, it will prompt "F1", "F2" option, choose the default "F1" to enter the view.The following specific steps refer to a closer article:Http://server.it168.com/a2011/0
FFmpeg can specify the number of threads to use when transcoding.
And for the same source, using the same transcoding machine, in the end how to configure the number of threads to achieve better efficiency, we did a simple experiment, the results are as follows:
Transcoding machine:

Thread is the number of threads per task, task is the number of transcoding tasks that run concurrently, time is time-

2. Although the power consumption of BGA increases, the electric heating performance can be improved due to the use of controllable collapse chip welding.
3. Low Signal transmission latency, greatly increasing the adaptive frequency.
4. Assemble common surface welding to greatly improve the reliability.
After more than a decade of development, BGA encapsulation has entered the practical stage. In October 1987, Japan's West Iron City (citizen) Company began to develop a plastic bal

Portability
Windows is designed to run on multiple hardware platforms. The original version of Windows NT supports the x86 and MIPS architectures. For the Alpha AXP platform of Dec (acquired by Compaq and then merged with HP), although it is a 64-bit processor, Windows NT runs in 32-Bit mode, Windows has also tried to support it. During Windows 2000 development, a native 64-bit version was not released. In the fourth-generation processor architecture,
