Delete disk partitions by mistake in ESXi
Because you are not familiar with ESXi commands and are careless, you accidentally delete the partitions of the ESXi operating system. The operation procedure is as follows:
Obtain disk device information:
[Root @ localhost: ~] Fdisk-l
[Root @ localhost: ~] Fdisk-l
**** ** The fdisk command is deprecated: fdisk does not handle GPT partitions. Please use partedUtil***
Found valid GPT with protective MBR; using GPT

The hard drive using the SATA (serial ATA) interface is also called a serial drive. In the 2001, the Serial ATA Commission, made up of Intel, APT, Dell, IBM, Seagate and Serial, officially established the ATA 1.0 specification, and in 2002, although serial ATA related equipment was not officially listed, serial The

The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM, Seagate, and th
hard Disk Interface
The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs

Solution Design
The provincial branches need to process a large number of voice and fax services, so the Cisco AS 5300 universal access server with a large capacity is used. Each local branch uses a Cisco 3640 router.

The most difficult way to achieve
1. Runtime generates shader and writes it to the FX file.
2. Call fxc to compile it into fxo
3. InProgramLoad fxo to generate Effect
Success on PC is the basis of shadertree.

First, I/O interfaces are inconsistent. Then, Windows phone7 content cannot be used to test HLSL
If you add a disk that has been installed with an operating system (such as a disk that has been installed with a Windows system) to the vSphere Client, you cannot directly add a drive, you need to log on to the ESXi console through SSH.Obtain disk device information:# Esxcfg-scsidevs-lMpx.

SCSI
Small Computer System Interface (Small Computer System Interface), which was first developed at 1979, is an interface technology developed for minicomputers. However, with the development of computer technology, now it is completely transplanted to a normal PC.
ATA (at embedded interface)
The purpose of this interface is to directly connect the bus in the at computer manufactured in 1984 with the driver and controller that are combined. The "at"

number is the primary flag, representing the number of slices in the normal IDE hard drive. For example, "2" means that there are 2 platters in the drive. In Seagate's SCSI drive, the primary ID is the speed of the hard drive. The second number is the secondary flag, which is the auxiliary flag for the hard drive. The secondary flag is valid only if the primary flag is the same or invalid. It is generally used to represent the algebra of hard disks, the larger the number of tablesThe higher the

Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to suppo

Not long ago, my old computer's hard drive broke down and there was a lot of information in it, so it was very depressing. I wanted to recover the hard disk data and asked about the price. I was shocked and decided to learn more about the hard disk restoration technology. You must have a full understanding of the overall physical structure of the hard disk before you have a deep understanding of disk opening data recovery. As an accessory with high precision, the external structure of the hard d
