best server hardware for virtualization

In response to the phrase "it is more difficult to win the world to keep the world", server maintenance is like "keep the world "! The network is paralyzed by a slight random gain. Maintaining servers requires a thorough understanding of the hardware, operating systems, and application software systems of the servers. It is also a system engineering, hardware Sys

Nagios monitors dell server hardware We have mentioned earlier that omsa is used to monitor dell servers, but it must be accessed through web. This time we use nagios + check_openmanage to monitor the hardware of dell servers. First, let's look at the figure below: We can see that there are two ways to achieve monitoring: 1. The nagios

I found that my own articles seem like Scientific and Technical tips. They don't have much technical content, and it's not very difficult to read them. They may even have no taste like boiled cabbage with clear water. However, these problems in the article are indeed encountered at work. They can be solved only after countless google or consult with colleagues. Some people may encounter the pain they have experienced. Therefore, to achieve the "Chinese Dream" as soon as possible, we should recor

Recently, a special issue encountered in the project, is the HP service charge 580 and H3C server for Xen virtualization, when the underlying installation of XenServer, whether using a CD-ROM or a USB flash drive or network installation is always prompted to find the installation media (Dell, Wave, IBM did not find a similar problem). Finally found that the installation of XenServer must be in the BIOS sele

We have previously talked about using OMSA to monitor Dell servers, but must be accessed via the web, and this time we combine nagios+check_openmanage to implement hardware monitoring for Dell servers.First, let's take a look at the following picture:It can be seen in two ways to enable monitoring:The 1.nagios server-side Check_nrpe call is implemented by the monitored check_openmanage, which is installed O

5 minute DBA-database server hardware selection describes some ways to help the database select hardware, which is actually biased towards MySQL... Simply put, it is of little significance to have a CPU larger than 8. You do not need to buy 4*4 Core or 4*6 Core because MySQL cannot be used at present. The larger the memory, the better the memory, the much cheape
