Install the raid driver without a floppy disk, whether it is a server2003-2008 or Linux or UNIX, BSD ...... You only need this software once! Easy to use! (The premise is that you must partition the raid disk first !) Usage!1. Download this tool! Decompress the package.2. Download the raid driver file of the correspo

RAID 0 RAID 0 is also called a zone set. It concatenates more than two disks to form a large-capacity disk. When data is stored, segments are distributed and stored in these disks. Because read/write operations can be performed concurrently, RAID 0 is the fastest speed at all levels. However, RAID 0 has neither redunda

the array mode. You can select different array modes such as, and 5, which correspond to RAID 0, RAID 1, raid 4, and RAID 5 respectively. -N2 indicates the number of active disks in the array, and the number of additional disks must be equal to the total number of disks in

disk faults. We recommend that you run all the databases in ARCHIVELOG mode without considering the RAID architecture. Oracle also recommends regular Oracle backup. Remember, the I/O subsystem consists of many components, including controllers, channels, and disk adapters, and the SCSI adapter-any crash of these components will cause irreparable disk errors to your database. Now let's take a look at the mo

I have described in detail in the Linux disk array technology (a) several types of RAID disk arrays, principles and detailed steps for creating RAID 0.

Run the fdisk command to create a partition. # fdisk /dev/sdb After entering the fdisk command line, Run Command n to create a partition, command t to change the partition type, command w to save the partition table and exit, and command m

In the article "use of software RAID in Linux", we talked about the basic concepts of software RAID in Linux and how to use mdadm program to manage software RAID devices, this section describes how to create, delete, stop, and expand a software RAID device, and how to manage its metadata and bitmap data. In this articl

the features that have not been made public. GEOM Background knowledge Before you introduce the configuration steps, it is useful to know the GEOM first. GEOM is the modular disk architecture introduced by FreeBSD 5.0. The module architecture allows you to manipulate the disk by writing a program. The soft RAID program introduced in FreeBSD 5.3 is the best example. Gstripe (8) can be done RAID 0 Gmirro

1. What is RAID1? RAID1, which can be called an image, writes data to multiple disks. For example, if A group of data is called A, data exists like this: A and A. In this way, data security is high, but performance is poor. Two or more groups of N disks are used as images for each other. In some multi-threaded operating systems, the read speed is good, and the write speed is slightly reduced. Unless the primary disk and image with the same data are d

RAID 0 + 1 is a combination of RAID 0 and RAID 1, also known as raid 10. Taking RAID 0 + 1 composed of four disks as an example, the data
