Article Title: how to create, delete, and restore hard RAID 1 in SunV440. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. On the Sun Fire V440 server, you can use the onboard Ultra-4 SCSI controller to configure the hardware disk image. It performs better than conventional software images that use volume management

deploying expensive fibre switch networks to connect traditional storage devices.In recent years, the transmission bandwidth of Gigabit Ethernet (1000Mbps, 125MB/S) has gained popularity and is expected to evolve towards Gigabit Ethernet. By then, the transmission bandwidth of the Ethernet will be 10 times times the transmission bandwidth of the various SCSI and Fiber channel protocols that the San relies on to survive. EMC company Celerra Products s
Introduction iSCSI (Internet SCSI) technology developed by IBM Research, is a hardware device used by the upper layer of the IP protocol can run the SCSI instruction set, which can be implemented on the IP network to run the SCSI protocol, Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines e
device, which generally corresponds to a specific driver. The secondary device number is generallyDifferentiate different attributes, such as different usage methods, different locations, and different operations. This device number is obtained from the/proc/devices file, so the driver is usually in the kernel first,In the directory. The main function of this device number (especially the main device number) is to declare the driver used by the device. Drivers correspond to device numbers one b
can be more convenient to build a disk array. Serial data lines due to only the use of four-pin structure, so compared with the mouth installed more convenient, more conducive to reducing the cable in the chassis, conducive to heat dissipation. Scsi SCSI (Small Computer system Interface) is a kind of storage cell interface model specially designed for small computer system, which can carry out dynamic di
(i) The concept of hard disk and its composition First of all, the concept of the hard disk: RTHK called the HDD, English name: Hard disk Drive, referred to as HDD, hard disk is one of the computer's main storage medium, consisting of one or more aluminum or glass-made discs. This is a hard drive: most of the hard drives are made up of a head arm bracket, a rotating shaft, a read-write head, a head arm, a track, a sector, a cylindrical surface, a disk surface. (ii)

Method 1:1. In the boot state, after inserting the disk, execute the command: echo "---" >/sys/class/scsi_host/host0/scan2. See if the command for step 1 is valid and can be verified in/var/log/messages3, execute fdisk-l command to see if you can see the new disk, if not see, you can change the above host0 to Host1 or host2, and so try againMethod 2:1.

operational expenses related to power, cooling and maintenance.2. Hybrid RAID SolutionFrom a hardware perspective, building a hybrid RAID solution can use any capacity SSD and HDD (though the number of SSDs and HDDs must be the same). If the RAID array uses a different drive size, the drive capacity is the smaller one. For example, a RAID 1 With 1 128GB SSDs and 2TB HDDs, the logical device is 128GB. A RAID 10 uses 2 128GB SSDs and 2 2TB HDDs, and the logical device is 256GB. The remaining HDD

Advantages of Optical Fiber As the successor of SCSI technology, fiber channel technology has three main advantages compared with its predecessor: Connection distance, scalability and performance. 1. Advantages of connection distance We all know that SCSI Cables cannot exceed 25 m at most, and this is only a theoretical value. In practice, when the number of devices on the
