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

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
If you have not installed a USB storage device on your computer, pair the user or component with the "deny" permission for the following files: Amp; #8226; % SystemRoot % infusbstor. PNF Amp; #8226; % SystemRoot % infusbstor. infIn this way, you will not be able to install USB storage devices on your computer. To "deny" permissions on the user or component pair u
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 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
Networked storage devices have many different characteristics, and joint de-dupe technology also faces different requirements:
