In linux, the simple establishment of a scsi shared disk requires that I have spare partitions, or I can add a disk to the virtual machine. I have added a hard disk to the virtual machine to install the required software, it is divided into a primary partition, sdb11G, which is shared with scsi. Modify the simple setup of scsi shared disk in s... linux To shar

First, we will introduce scsiscsi, which is called "Small Computer System Interface" in English and the Chinese name "Small Computer System Interface ". It is a peripheral interface, which is mainly used by hard disks on servers. In addition, this interface is also used for CD/DVD-Rom, CD-r/RW, scanners, and tape drives. In fact, SCSI is not a new interface type. As early as 1986, the SCSI standard was deve

Some time ago, just use a new computer, due to limited funds did not match the long-desired SSD. I did not feel the feeling of flying, always reconciled, think carefully. I'm dead pretty large storage, we can assume that part of the memory as a hard drive to get it out. No faster than SSDs, let's start.First of all. All we have to do is write a hard drive controller driver, we know. The driver of the storage type generally adheres to the structure of Class/port/miniport driver. Microsoft has fin

The SCSI low-level driver is for the host Adapter. When the low-level driver is loaded, you must first add the host adapter. Host adapters can be added when the PCI subsystem completes ID matching, or manually added. All host adapters Based on the hardware PCI interface adopt the previous method, while the unh iSCSI initiator adopts the latter method. Adding a host adapter includes two parts: assigning a data structure to the host adapter and adding t

What are the differences between VGA, DVI, RS232, UART, SCSI, SATA, and other interfaces?Both VGA and DVI are video transmission lines. The former is a traditional analog transmission, and the latter has many types, which only transmits numbers or analog or digital models. In short, the latter's video signal transmission quality is higher than the former, and the transmission speed is faster. At present, many monitors on the market use DVI interfaces

Not every place running Solaris operating System has the resources to backup the solution, and they don't even need those resources, such as expensive tape-changer, tape library, or Tape Silo. What is usually needed is a backup or ufsdump of the root file system, an important database, or a small development entry code. In these cases, external devices such as SCSI DDS tape drives are usually sufficient. The following information is useful for config

Some time ago to do some of the SSD optimization work, SSD's biggest problem is that after a long time use, IO performance will drop dramatically. The main problem is that in order to prevent the "write amplification" problem, SSD firmware uses a similar log algorithm, when the storage resources are basically depleted, in each write operation firmware can only do garbage collection (garbage collection, GC) operations, This introduces a lot of time-consuming operations, such as the erasure of NAN
