program to the latest version, let's start the kernel compilation of the journey. Preparatory work The first command to run normally is: #cd/usr/src/linux;make Mrproper This command ensures that there are no incorrect. o files and dependencies of files under the source code directory. Since we are compiling using the full source package just downloaded, this step can be omitted. And if you use these source programs to compile the kernel many times, it's best to run the command first.Ensure th

The hard disk interface is a connecting part between the hard disk and the host system, which transmits data between the hard disk cache and the host memory. The different hard disk interface determines the connection speed between the hard disk and the computer, in the whole system, the quality of the hard disk interface directly affects the program running speed and performance. General classification and large class classification From the overall point of view, the hard disk interface is d

Disk media in the storage area is the most critical device, and all data and information is stored on disk media. The reading speed of the data is determined by the connection interface of the disk media. We used to do data storage through SCSI or SATA interfaces and hard drives. But in recent years a new technology has increasingly been favored by small and medium-sized enterprises and even large enterprises. Is the SAS technology and its correspondi

The representation of the hard disk in Linux is www.2cto.com 1) IDE hard disk, expressed in hd. Hda indicates the first IDE hard disk, hda1 indicates the first partition of the first IDE hard disk, and hda2 indicates the second partition of the first IDE hard disk ...... hdb indicates the second IDE hard disk, hdb1 indicates the first partition

), so many readers, even enterprise users who have used the SAN storage network know about the SAN Switch. To this end, this article will introduce the things you need to pay attention to when purchasing a SAN Switch. In fact, it will introduce the main features of the SAN Switch. First, let's have a brief understanding of the origins of the SAN switch, so that we can have a better understanding of the SAN Switch, no longer full of "mysterious" colors. Origin of SAN Switches Previously we saw t

The storage design leveraged by the host server architecture has a significant impact on host and guest performance. Storage performance is a complex mix of drives, interfaces, controllers, caches, protocols, Sans, HBAs, drivers, and operating system considerations. Typically, the overall performance of a storage architecture is measured by maximum throughput, maximum IO operations per second (IOPS), and latency or response time. Although these three factors are important, IOPS and latency are m

/src/Linux # Make mrproper This command ensures that the source code directory does not contain the correct. o file and file dependencies. Because we useDownload the complete source program package for compilation, so this step can be omitted. If you use these source code for multiple timesTo translate the kernel, run this command first. Make sure that the ASM, Linux, and SCSI links in the/usr/include/directory point to the source code of the kernel t

a Windows system. You do not have to borrow any third-party software package. 1. Create a CD image file from the CD. Put the CD in the optical drive and execute the following command. # Cp/dev/cdrom/home/sunky/mydisk. iso or # Dd if =/dev/cdrom of =/home/sunky/mydisk. iso Note: You can execute any of the above commands to make the current CD in the optical drive into a CD image file/home/sunky/mydisk. iso 2. Make the files and directories into a CD image file and execute the following command.

next command. /Dev/rmt/0b: use the tape interface, that is, the behavior of BSD. Various types of operating systems such as AIX, Windows, Linux, and FreeBSD are more readable. /Dev/rmt/0l: Set the density to low. /Dev/rmt/0 m: Set the density to medium. /Dev/rmt/0u: Set the density to high. /Dev/rmt/0c: Set the density to compression. /Dev/st [0-9]: Linux-specific SCSI tape device name. /Dev/sa [0-9]: FreeBSD-specific

I. Hardware and equipment filesIn the Linux system, the hardware devices are in the form of files, because different hardware devices have different file types, we refer to the hardware and system corresponding files are called device files. The device file provides an interface between the external device and the operating system, so that the user uses an external device as if it were a normal file.1. Device filesThe device file is stored under the Linux system under/ Dev , the device file nami
