There are now two main hard disk interface technologies on the server, SATA and SCSI, and the products that use SAS hard drives are currently listed, and of course high-end optical drives, the first two of which are the most common. Here we have a brief introduction to SATA, SCSI, SAS and other interface technologies.
Sata
SATA (serial Advanced Technology attachment) is the abbreviation for Serial ATA, which is currently available SATA-1 and SATA-2
system's registers to pass the hard drive's addressing parameters, it uses its own address pack, which holds 64-bit LBA addresses, and if the hard drive supports LBA addressing, delivers a low 28-bit address directly to the ATA dialog box , the operating system converts the LBA address to the CHS address and then to the ATA dialog box if it is not supported. In this way, it is possible to CHS addressable m

database created by the Qsqlquerymodel class to read and write to the inherited Qabstractitemmodel classAt first we talked about that the model is read-only by default, so we can't modify the contents of the table in the window. But we can create our own models and then display the data and modify the data as we wish.To make it readable and writable, you need your own class to inherit from Qsqlquerymodel, and rewrite the SetData () and flags () two functions. If we want to change the display of

problem that the identification mode of a SATA hard disk is ahci, and the installation of the driver is also a problem.
Check whether the computer's CPU is Intel or AMD. Otherwise, the ahci solution is not legal. The CPU of this machine is AMD.

1. Start the Dell Computer and press f2 to go To the BIOS interface. Then, you can change the SATA mode from ahci to Ata. The XP is installed normally in the original version.

1: Due to work, I have been engaged in the development of 2 * 36port Expander in LSI for the past few months. It mainly parses and processes the SSP, SMP, and SES command protocols in SAS.
The SDK of LSI uses the threadx operating system. The kernel of its chip is ARM920T, which provides the SAS protocol processing function at 920t. I personally feel that the Code style is not good.
My personal understanding of expander is as follows:
The lsisas2x36 is a 36-port, 6.0-Gbit/s Serial Attached SCSI

It is very easy to burn a CD in Linux. Just enter the following command in the terminal window:

Cdrecord software is generally available in the release version. if the system is not installedIt should be available in your installation disk.

What is SAS?
SAS is a new generation of SCSI technology, and the popular Serial ATA (SATA)Hard DiskSimilarly, serial technology is used to achieve higher transmission speeds and improve internal space by shortening the connection lines. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the efficiency, availability, and scalability of the storage system, and is provided with Serial

How can I change the PIO transmission mode of a hard disk?
Let's talk about how the problem arises. In Windows 2000/XP/2003, there is such a setting: Windows IDE/atapi port driver (atapi. sys) after receiving a total of six timeout or cyclic redundancy check (CRC) errors, the driver will forward the communication speed (transport mode) from the fastest Direct Memory Access (DMA) the mode is step-by-step reduced to a slow DMA mode.
