(These software is used for the operating system already installed on the server)Third, the correct identification of your array card model (in this case, Dell for example, in
In the server hardware monitoring, the current industry is mainly based on the following two kinds: 1, the server comes with tools, such as HP's Hpacucli,dell OMSA, etc. 2. Intelligent Platform Management interface (IPMI, full name intelligent Platform Management Interface) Based on the above two kinds, through the Nagios, Zabbix or self-research operation and maintenance platform, such as the package, to carry out early warning operations. As the servers used by the company are all Dell
Dell announced at the LinuxWorld Conference in Frankfurt that it will Install Novell's SuSE Linux operating system on its Dell poweredge server as part of its global agreement with Novell.
At a press conference on the Agreement, Judy chavis, Dell's Global Alliance marketing director, said Novell's SuSE Linux Enterprise Server 9 would be used on servers like poweredge 1850, 2800, and 2850, the annual subs

Overview of basic data of the websiteAccording to 2010 statistics, Youku daily average number of independent visitors (UV) reached 89 million, daily average visit (PV) is reached 1.7 billion, Youku with this data to become the Google List of the top domestic video site manufacturers.Hardware, Youku introduced the Dell server mainly in the PowerEdge 1950 and the PowerEdge 860
system performance is good.
It is acceptable if the number of active processes per CPU is not greater than 4.
If the number of active processes on each CPU is greater than 5, the system performance problem is serious.
You can also use the vmstat command to determine if our system is too busy. If it is determined that it is very busy, consider whether to change the server or increase the number of CPUs. Summary:
If r is often greater than 3 or 4 and the id is often less than 50, it indicates tha
Recently, our company deployed virtualization, purchased two Dell R710 Server (cpu:64 dual-core, frequency: 2.4GHZ, 32G memory, hard disk: 2 300G do Riad 1, 3 block 2T do Riad 5, 10 block network card), VMware ESX 5.0 was installed on both servers because the virtualization knowledge was only used by some of the client's virtual machine software, groping to today, encountered a lot of problems, looked up a lot of information, took a lot of detours, with the problem to solve the problem of the pr

This completes the installation of OMSA on a Linux server over the Internet.Friendly tip: The Omsa version of Yum Repositor may differ from the version update time published on the website. In this case, Yum installs the version of Omsa v7.3, the official website has been out of the latest patch v7.3.0.1, please note.

Reasons and solutions for the loss of network card of Linux virtual machine under Hyper-V virtualization The company has implemented virtualization, all using Microsoft Windows R2 Enterprise with Hyper-V makes the cluster run Hyper-V virtual machine. This is a good thing, save resources, centralized management, power saving, deployment ultra-fast, the key is to live migration. We use the Dell Md3000i enclosure as a clustered shared disk, which is iSCSI-based Gigabit Ethernet network storage, a

In fact, it is through the dmidecode command output, and then through the sed,awk,cut command processing. 2, this footstep applies to the HP DL series of servers, the Dell PowerEdge series will have a little content different, so there will be a small tabloid error in the crawl process.3.

First determine if the power supply is normal, then replace the memory, CPU, motherboard. (I encountered a bad memory, the server can not get up
