, the following identification is used: A,b,c,d,e and F-represents a block of data p1,p2,p3-represents a block of parity information RAID 0 RAID 0 Features: A minimum of two disk data stripe distribution without redundancy, the best performance (do not store the image, check information) can not be applied to the high data security requirements of the occasion RAID 1 The following features are RAID 1: a minimum of 2 disks is required to provide da

In the last three years, the incidence rate of bank card crime has been increasing but the rate of detection is still to be improved, "Yesterday, in the province's public security departments to combat and prevent economic crime propaganda day activities, provincial Public security Bureau through the investigation bureau to crack down on bank card crime director Liu received this reporter's interview, detailed bank card crime of the latest trends, He said the public Security Department is workin

only partially compensate for the negative performance of bitmap. 4655 lines, issued bitmap bulk write request.4657 lines, update the serial number of the bitmap bulk write request. 4658 lines, will wait for bitmap to write the strip issued. 4660 raid5_activate_delayed (conf); 4660 lines, look at the function name is the activation of the delay stripe meaning. So why delay the handling of the stripe? I

From a common application, the requirements of the storage system has good IO performance also requires the protection of data security work, so raid10 and RAID5 should be our focus of attention. Simply talking about the advantages of different RAID levels is impractical, and raid is only a complete array with disk binding. The following from the IO performance, data refactoring and the impact on the system performance, data security, etc., combined with the status of the disk to analyze the d

To give you illustrator software users to detailed analysis to share the drawing of linear fringe geometric art patterns of the tutorial. Tutorial Sharing: First, create art brushes To make a stripe pattern, the first thing we need to think about is what tools are used to achieve it more quickly. Because such as stripes, dots, squares ... This kind of basic pattern has the common character that repeats a certain visual law

This article explains the basic principles of disk array raid0,raid1 and RAID5 and their differences, so that you could refer to when configuring the server ... RAID 0: Stripe group without error controlTo implement RAID0 must have more than two hard drives, RAID0 implements the stripe group, the data is not stored on a hard disk, but is divided into blocks of data stored on different drives. Because the da

of the data, prevent a hard disk in the array corruption, resulting in the loss of all data, RAID also provides redundant information, so that the damaged disk in the array can be replaced by other disks. Currently, the more popular raid includes the RAID0,RAID1,RAID5 and their comps. RAID0 provides the functionality of stripe, and simply pieced together the disks in the array, and any one of the disks is destroyed, resulting in a total annihilation;

group with an AU size of 16MB and fine grain striping size 1MB (previously 128KB)This lowers the extent map size to the original 1/16. The AU parameter can only be used when the disk group is set up. When a disk group is established, you cannot change the size of the AU for this disk group In order to change the AU size (that is, the data extent size), you must reset the following ASM implicit parameters: Change from 1MB to 16mb,fine grain stripe siz

types of logical volume mapping modes:Linear mode-maps a range of physical blocks to logical blocks in order, which is the default mapping method. For example, map 1-25 of Le in a logical volume to PV1, and 26-50 of Le to PV2.Stripe mode-the logical block is mapped to a different physical volume in the form of a stripe, which is somewhat similar to the previous RAID 0, which improves the performance of the
