B. What is Lun?
Lun ID is not equal to a device, but a number. It does not represent any physical attribute. In our actual environment, the Lun we encounter may be a disk space or a tape drive, or media changer.The mystery of Lun (compared with some new users) is that it is often not a visible entity, but a virtual object. For example, if a

2. storage devices are formatted to create a Linux File System;
1. Introduction to the Linux File
The first problem with using QT to make a Kindle annotation management software on a MAC is to detect the status of USB devices connected to your Mac. If the development is in Cocoa, there will be a corresponding system API to use, but because I was in the QT platform development, so it is a bit more difficult. Just then, I found a library:libusb

How to disable USB flash drives, disable USB storage devices, and prohibit USB flash drives from copying computer filesUSB flash drives and mobile hard disks are currently widely used USB storage tools, which greatly facilitates work. But at the same time, employees can easily copy computer files through USB flash drives, mobile hard drives, and other security me
This article explains the Zabbix monitoring of Dell Compellent storage devices through the SNMP protocol.The monitoring of the idea and monitoring network equipment is the same: first determine whether the device supports SNMP protocol, if supported, the next step to get the device's private MIB library, usually to the manufacturers to obtain or download online. If you do not get the MIB library, the value
Many versions of common Linux files have been updated. I personally think that common Linux Files are a good file system. I would like to recommend this to you. Today, the technology is constantly updated and all kinds of files used have been eliminated. I think there are still good files, such as common Linux files, which are worth using. In common Linux Files, file system management is extremely important and basic. A storage device can be used only

The Network Storage Device of the embedded Linux operating system-general Linux technology-Linux programming and kernel information. The following is a detailed description.
Network Connection Storage Technology
Network Connection storage is a new storage technology used for network content
Networked storage devices have many different characteristics, and joint de-dupe technology also faces different requirements:
More sensitive to energy efficiency
The use of operational resources is required to decompose data into basic elements and indexed storage, and reverse operation to revert data after repeated deletion to the original state for front-end
The disk array is the most common storage device, from the simplest single control disk array to the complex matrix switching structure of the multiple-control array, can meet the different levels of application requirements. The single control disk array composition is simpler, its core is a RAID controller, in a cabinet can configure more than 10 disks, through the RAID controller implementation raid function. This disk array typically supports the
