In recent years, customers have always asked original storage engineers about the storage RAID plan (RAID, 5, 6 ....): "How many RAID are used? What RAID level is used? Why is RAID at this level used? What are the benefits of this level? Wait, "the storage engineer may be ti
As we all know, CPU chip and graphics subsystem performance is soaring, but the corresponding disk subsystem performance is becoming more and more serious performance of the overall system bottlenecks. While disk technology is ata/100 today DMA66 tomorrow, none of these specifications can fundamentally improve the capabilities of the disk subsystem. It's only raid (here we refer specifically to IDE RAID tec
In addition to using RAID cards or chips on the motherboard to implement disk arrays, we can directly use software to implement RAID functions in some operating systems, for example, the RAID function is built in Windows 2000/XP.Before learning about RAID in Windows 2000/XP, let's take a look at Dynamic Disk management
In the current era of large data explosion, more and more enterprises pay more attention to the data security of enterprises, the integrity of data, then how to protect the enterprise data bank security, lossless? Then we use RAID technology, which is now a very hot virtualization, cloud computing, the bottom of the raid storage is used to complete. So what is RAID
Early due to raid is often used to combine some inexpensive SATA interface hard disk devices to complete redundancy.So the early full name is: redundant array of inexpensive Disks (inexpensive redundant disk array). Today, RAID is also used by most businesses to combine SCSI and SAS interface hard disk devices.So now the full name is:redundant array of independent Disks (independent redundant disk array).

increases fault tolerance.Level classification for RAID:RAID 0: The data is evenly distributed across the array's disks in strips, so that the system has data requests that can be executed in parallel by multiple disks, each of which performs its own portion of the data request. The parallel operation on this data can make full use of the bus bandwidth, and significantly improve the overall disk access performance.Hardware requirements: Minimum of 2 disksPerformance advantages: Very high disk r
What problems should individual users pay attention to when building RAID, or a disk array?1. Q: What RAID solution should I choose, and the motherboard With RAID function? RAID Controller? Or software RAID?A: In fact, RAID soluti
Early due to raid is often used to combine some inexpensive SATA interface hard disk devices to complete redundancy.So the early full name is: redundantarray of independent Disks (independent redundant disk array). The primary function of RAID is to combine multiple hard disks on the motherboard in a specific way, organized into a logical whole with specific characteristics, and then output to the operatin
RAID Mode IntroductionThe Orico 3559RUS3 HDD enclosure provides five types of disk array build modes, including RAID 0, Raid 1/10, RAID 3, RAID5, Combine, which have different functions, as explained below.RAID, the English "Redundant Array of independent Disks" abbreviation
:6.0gb/smedia type:hard Disk devicedrive temperature:30c (86.00 F) ..... ............ In the command results message, note the status of Firmware state: If the status is online, the disk has been made into a RAID array, and if the status is unconfigured (good), the disk is not made into a RAID array. But the status OK. The above command shows that the first 2 disks of 4T were made into
RAID Basic Concepts, Special terminology introduction We offer RAID cards to support a variety of commonly used RAID levels, such as 0,1,5,10,50, you can choose based on the importance of the data, before starting to use the RAID card, we hope you can have a deeper understanding of the following concepts, so as
Raid 10:
Make at least four hard disks into RAID 1. If there are four hard disks, there will be two to rand1 disks. If there are eight hard disks, there will be four to raid 1 disks, the biggest purpose of raid1 is to ensure high data security and high read/write speed, but to sacrifice half of the disk space. If the number 12345678 is written to a request, the w
Server RAID 5 Data recovery caseThis shared case is a RAID disk array in a server, with 12 disks in the disk array, a single-disk capacity 500g,ext3 file system, and a Linux platform for the system platform. Raid in 2nd and 6th, two hard disks reported yellow lights, management personnel after the check on the 6th plate has been forced on-line operation, forced o
A. RAID Technology detailedRAIDis Englishredundant Array of independent Disksthe abbreviation, translated into Chinese means"Redundant array of independent disks", sometimes referred to as a disk array (Disk Array). Simply put, RAID is a combination of multiple separate hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), providing higher storage performance tha
The raid:redundant Arrays of inexpensive disk is an inexpensive redundant array of disks that can be organized in different ways to improve IO capabilities, or improve durability, for multiple hard drives. RAID can be divided into soft raid and hard raid, soft raid through software implementation, hard

Author:Small PFrom:Linuxsir. orgAbstract:Data damage and loss caused by various disasters and errors cause losses and inconvenience to people. Data on personal and website servers must be backed up. Raid is a feasible and effective method. Raid is divided into soft RAID and hard
Enterprise-level database applications are mostly deployed on RAID disk array servers, which can improve disk access performance and implement fault tolerance and Disaster Tolerance. RAID (redundant disk array ),
Enterprise-level database applications are mostly deployed on RAID disk array servers, which can improve disk access performance and implement fault tol
For a long time, we have seen a lot of competition over the performance of RAID 5 and raid 10. Even many people have come up with test data, but who is the right. Here, I will analyze the internal operating principles of these two raid types. Under what circumstances should we choose which raid mode.
