Deep analysis of disk caching mechanism under Linux and the problem of SSD's writing amplification

Some time ago in developing a system that uses SSD for caching, a large amount of disk caching occurs when writing data at high speed. Too much disk caching is very dangerous if there is a problem with the machine if it is not written to disk in a timely manner, which can result in a lot of data loss, but if the data is brushed into the disk in real time, the write efficiency is too low. In order to understand the Linux system of this disk write chara

Must SSD be PCIe for enterprise-level servers?

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are o

Mac Pro after replacing the SSD, enable the Achi method under Win7 AHCI

After replacing the SSD under Mac Pro, it is cumbersome to change the SSD to AHCI mode if Win7 is installed. This article describes how to change the SSD in Mac Win7 to AHCI mode driver and the processing of several common problems.How to change the SSD drive mode of Win7 to AHCI when Lion and Win7 dual system coexist1

4K corresponds to 4096HDD Mode:First, let the SSD run in AHCI mode:AHCI, the full name Advanced host controller Interface, which is the high-level hosting controllers interface, is more suitable for SSD SATA storage device communication protocols than the older "IDE" virtual mode. In AHCI and IDE mode, the SSD's performance gap percentage is around 65%. Therefore, it is recommended that

Application of SSD in SQLServer

I. first, review the read and write features of SSD (1) Limited write times; (2) best random read performance; (3) Good sequential read performance; (4) Poor sequential write performance; (5) the random write performance is the worst. In terms of storage, different content of SQLServer has its own unique personality. The following lists TempDB, Data, indexes, and transaction logs respectively. I. first, review the read and write features of

PostgreSQL Introduction and performance improvement of PCIe SSD

In the relational database area, PostgreSQL is a very popular open source database software. Since its release in 1996, it has accumulated nearly 20 years of practical experience, both in PostgreSQL itself and in community ecology. Not only small and medium-sized enterprises, many large industry customers will also use PostgreSQL to build their own database system. This article focuses on PostgreSQL and compares the SAS disks in the PCIe SSD (this art

SSD (Solid StateDisk) and HDD (Hard Disk Driver) Simulator Researc

files are in use. DiskSim is initially separated from a large, system-level simulator, so it can be easily transplanted to the entire system simulator (such as porting to SimOS ). What DiskSim Does Not Do?DiskSim only simulates and reports storage subsystem performance-related aspects. It does not simulate the behavior of other computer system components, or the interaction between components and the storage system. DiskSim simulates the performance of the hard disk system, but does not save th

Performance comparison of mechanical HDD SSD USB drive

in sequential read and write performance, sequential reading can reach the 82.4mb/s, basic and mechanical hard disk performance level, the random read and write performance slightly improved, not very obvious. Considering the high requirements of TC for Random Read and write performance, the USB drive with 3.0 interface is still difficult to meet the performance requirements.2.3 Test Result AnalysisCombined with the above test results, slow write speed is the main performance bottleneck of the
