Explain various raidRAID0:It's usually done with two plates.Write a file on two plates, respectively.This improves read and write speed.But it is not redundant and cannot be recovered by backup after data lossRAID1:It's done with two plates.That's what they call a mirror.Backup for each otherOnce a piece of data is lost, it can be recovered by another pieceRAID5:At least three plates requiredRAID5 is a compromise between RAID0 and RAID1.So it's 10/2=5.20170713l08-00 old boy Linux OPS training-de

If the total capacity of the hard disk is greater than 2T, the system cannot be installed in MBR format.Use GPT formatYou can't use Fdisk to partition it at this time.To use parted to partitionMore than 2t hard disk partition, the old boy video used to 5 pieces of 600G hard diskThere are several ways to install the systemI only remember two of them.Method One: Take 2 pieces of RAID 1 for the remaining 3 pieces to do RAID5Method Two: All made RAID5, then the logical partition installation system2

the utilization of system resources can be very high, thus reducing the performance of systems. Software RAID is not required to add any additional hardware devices, because it relies on your system-primarily the CPU's functionality-to provide all available resources. • Hardware RAID is usually a PCI card, and you will see the processor and memory on the card. Because the processor on this card can already provide all the necessary resources for rai

Dellr710 server, there are 4 450G hard drives, the default do RAID5. Our aim is to take one of the 3 hard drives to do RAID5, leaving a hard drive to do hot standby. Here, let me give you a concrete explanation. ① 4 Hard drives made of RAID5 ② 3

Memory overflow and Memory leakage, memory overflow and Memory leakage Basic Concepts Memory overflow out of memory means that the program does not have enough memory space for use when

When we use C + + as the underlying driver, we often encounter a warning of insufficient memory, the reason is often because of memory overflow, leakage or cross-border and other reasons. So what's the connection between them? memory overflow (out of memory) Refers to a program that does not have enough

when we use C + + to do the underlying driver, often encounter memory shortage warning, the reason is often because of memory overflow, leakage or cross-border reasons.

Http://bbs.gameres.com/showthread.asp? Threadid = 57428 The excerpt is as follows: Three types of memory, such as the local memory and system memory of the video card, all of us know that the local memory of the video card is the memory of the video card, and the system

Memory-Working set: the sum of the amount of memory in a private working set and the amount of memory that the process is using and can be shared by other processes. Memory-Peak Working set: The maximum number of working set memory used by the process.

Android obtains the total memory and available memory of the mobile phone. In Android development, sometimes we want to obtain some hardware information about the mobile phone, such as the total memory and available memory size of the Android phone. How can this be implemented?By reading the "/proc/meminfo" file, you c

How to set the optimal 4G memory virtual memory ?, 4G memory virtual memory Memory is one of the important components in the computer and serves as a bridge to communicate with the CPU. So, do you know how much virtual memory sho

From the compiler perspective, memory is divided into three situations: 1. The memory area that has been determined during system initialization and will not change. It generally refers to global variables and static variable arrays. 2. memory on the stack: generally refers to the local variables in the function. The memory
