raid Introduction: RAID (Redundant array of inexpensive Disks) is called a redundant array of inexpensive disks. The basic principle of RAID is to put multiple inexpensive small disks RAID level description; generally used RAID class, Are

Graphic RAID 0, RAID 1, RAID 5, RAID 10 RAID (Redundant Array of Independent Disk Independent Redundant Disk Array) technology was proposed by the University of California at Berkeley in 1987, initially to combine small cheap disks to replace large expensive disks, at the sa

When the Iomega device has no small display and no external video interface to connect the monitor, it is necessary to discover the IP address of the device over the network. This article describes how to discover the IP address of a device through the client's ARP list. First, the RJ-45 network interface of the Iomega device is directly connected with the RJ-45 network interface of the client PC, and

Access to Iomega storage through the Linux operating system often uses the NFS protocol. Linux host if you want to access the Iomega on the share, you need to do the following settings: Take the 4.1.102.29716 version of the Iomega px4-300d model for example, first find and enable NFS items in the Protocol feature; After the NFS feature is turned o

Question: What is a RAID level? What does the raid level mean? RAID technology is divided into several different levels, offering different speeds, security, and price/performance. Choose the appropriate RAID level to meet the user's requirements for storage system availability, performance, and capacity, depending on

In the 4.0.8.23976 firmware version of the Iomega device set up a copy of the job plan, to the time after the plan does not work properly, but manual clicks can be normal operation. Solution: This is the 4.0.8.23976 firmware version of the bug, the solution is to update the user device firmware version to the latest version. Take the 4.1.102.29716 version of the Iomega PX12-450R model for example, click "

Take the 4.1.102.29716 version of the Iomega px4-300d model as an example, first we log into the Iomega Device Management page, open the "network" management functions; In the network settings, open "Connect network interface", the other network card selected, select "Apply". Click "Modify Network Settings", in the bounce out of the dialog box can choose multiple network adapter binding

1, first open the SSH port settings interface Https://x.x.x.x/manage/diagnostics.html Note: x.x.x.x is the Iomega storage of the management port IP Set the root user password, such as admin 2. Use Remote connection tool to login Iomega storage, such as putty Note: x.x.x.x is the Iomega Storage management port IP 3, enter

IX-Series Iomega storage by modifying the URL of the Web admin interface. html? "The previous field is" diagnostics ", why not enter the Support diagnostics interface? Solution: Unlike the Iomega PX series, the IX-series Iomega storage needs to be modified in the URL ". html" If it needs to go into the support diagnostic mode for dump log downloads or to turn o

The management of Iomega Device subfolder security permissions is done through domain management mechanisms. Take the 4.1.102.29716 version of the Iomega px4-300d model as an example, first we log into the Iomega Device Management page, open the "domain Management" function; Select "Enable" Domain management, enter the name of the domain to be joined, a

Normal user role when using a browser to log on to Iomega's PX family home page, the default is to not be able to view its own user data, and the home page can only modify its own password. You can modify the default settings to enable the normal user role to access user data on the browser interface. Take the 4.1.102.29716 version of the Iomega px4-300d model for example, first open the Home Settings feature item. Enable the Confi

When you mount the Iomega Storage shared NFS file directory with the Mount command, there is a possibility that the error message "Mount:wrong FS Type,bad Option,bad block on ..." appears.Solution: First, the connectivity of the network is confirmed; If the error is still, check the/sbin directory is not/sbin/mount.nfs files, installation nfs-utils can (request can connect the Internet); Using the command to install, Ubuntu commands

Solution: Unlike the Iomega PX series, the IX-series Iomega storage needs to be modified in the URL ". html" If it needs to go into the support diagnostic mode for dump log downloads or to turn on SSH functionality. "The previous field is" support ". Also, the IX series does not allow users to enter user names and passwords for SSH logins when setting up support for SSH logon access. The username/password

Shares created automatically for users when creating users cannot be displayed in the Content manager, this is a product bug, and it is recommended that you do not select Add protected shares to this user at the same time when creating a user.

The display language of the Iomega management interface can also be set on the local monitor. Please note that only the Iomega device hardware has VGA and other video connectors to connect the monitor to set up. Connect the monitor, keyboard and mouse on the equipment, turn on the power of the equipment, turn on the monitor, find and turn on the "language" function in all functions; Choose Sim

The administrator first needs to open the Iomega Support diagnostic mode, specific reference Knowledge Base number: 138287 Open an SSH tool that supports Chinese, such as putty; According to the diagram, select UTF-8; Back to the session interface, input Iomega device IP, click "Open"; Enter the password after landing,VI device/etc/profile file, add the following two lines in t

Raid implementation:Raid: cheap redundant disk array, which turns several hard disks into a wholeLater, because it lost its original cheap purpose and became very expensive, it changed its nameIndependent redundant disk arrayAlthough we cannot implement raid on hardware, we can still implement raid because of our limited strength and we didn't buy those devices.N

Iomega Device export dump logs need to go into the support Diagnostics interface and need to modify the URL in the URL ". html?

Recently, I was thinking about a cheap and convenient way to integrate cinder with LVM driver, that is, a raid hard disk consisting of cinder + LVM + multiple disks. In this case, you need to consider what raid should be used based on read/write requirements and available resources, and how to choose the raid mode. There are two

Raid 10 Vs. RAID 5 performance provides a Performance Data graph that uses sqlio. EXE to generate 8 KB random reads and writes, with a performance gap nearly doubled. Disk access time = disk seek time + latency Latency = 1 minute/RPM/2 The main factor determining iops is the array'sAlgorithm, Cache hit rate, and number of disks. The array algorithms vary depending on the array. For example, in hds
