of the Intel 82545EM Gigabit Ethernet card, and basically all of the OS are E1000 driven, so compatibility is the best. Vmxnet 2 is an older generation of parallel virtual web, only applicable to esx/esxi3.5 and above the limited customer operating system, vmxnet 3 relatively new, but it seems only applicable to virtual machine version 7 virtual machine (virtual machine version set in the first two steps, The version recommended for use in ESXI5 is 8). These two cards provide better performance

In VMware vsphere Web client, you can add a new SCSI controller to the VM. The options include the following types. What are their differences? How to choose? Buslogic parallel One of the earliest vscsi controllers on the VMware platform. the first version of Windows has its driver by default, making it easier to install a specific version of Windows. the performance is incomparable with that of the LSI logic driver. Because the queue depth in t

we do? Similarly, we will write a general example of row compression: In this way, we compress a matrix of m rows to a matrix of R rows, which is the same for SVD. we multiply the two sides of the form of SVD decomposition by the U transpose U' In this way, we get the row compression formula. It can be seen that PCA is almost a packaging of SVD. If SVD is implemented, PCA is implemented. What's better is that with SVD, we can get PCA in two directions. If we break down the feature value of a' A

In the past few days, the write policy of the RAID card is switched back to WT from WB. If "Learn cycle" occurs during business peaks, it will seriously affect the performance of the database. After the problem is solved, sort out your understanding of these problems. I will not describe the megacli command set I have used. There are a lot of information about it on the Internet. We recommend related articles by Tan and ye from Chinese documents. I will explain the problems related to the RAID c

1 IntroductionThe RAID card battery on the server, referred to as the BBU, is a very important component, it has a large impact on the I/O performance of the disk, but the general Bbu power can only be used for 90 days, the system will automatically charge it after the power is exhausted, but it usually takes a few hours to charge, during charging, The cache status of the RAID card is in write through, i.e. without the caching feature. So in order to ensure that the server is in normal operation
