page in InnoDB Buffer The ratio in the pool, as well as the instant I/O status, determines the period of the pages flush. if the scale of the dirty page in InnoDB Buffer pool reaches the percentage threshold set by the innodb_max_dirty_pages_pct (default 75) parameter, the INNODB database engine will follow the Innodb_io_ Capacity_max (default 2000) the number of parameter settings synchronizes this dirty page to disk . When disk I/O performance is insufficient and the innodb_io_capacity set

You may have touched a lot of mobile hard disk, u disk, such as mobile storage devices. While virtual storage may be more or less used by all of you, the most common one may be a network hard disk (that is, a network disk). Tencent Micro Cloud can be said to be one of the cloud storage-related products. Micro Cloud Network disk is a collection of file synchronization, backup and sharing functions of the cloud storage applications, so that your mobile phone and computer automatically sync files,

It is well known that after the upgrade of SSD, the speed and performance of the computer have been greatly improved. However, some users upgrade SSD, speed and performance improvement is not obvious. The reason is that the SSD is not properly used and the operating system is installed. The common problem is that the 4K is not aligned, does not turn on the trim,

Q: Vsan needs to use SSD, what's the use of it? A: SSD is used for read caching (70%) and write Buffering (30%). Each write will go to SSDs first, and then cancel the staging to the HDD later. Q: When you create a VSAN virtual machine storage Policy, when should you use the "allowed number of failures", when should use "stripe width". A: The number of allowed failures is related to availability, and you c

Jar question: We all know that ESXi 5 supports using SSD disk as host cache, and today I have a simple experiment, I use a Samsung 830 SSD disk, I found that can identify the drive type of SSD. and the SSD host cache has been successfully enabled with this disk. My understanding is that when the host memory is not enou

the difference between SSD and common hard disk In fact SSD solid-state drives are solid-state storage, belong to flash memory, long service life, not easy to damage, strong earthquake resistance. The disadvantage is: The price is expensive, the capacity is small. Ordinary hard drive inside a platter, work through high-speed rotation to read and write information, very afraid of vibration, easy to damage,

For details about bcache reprint, refer to http: blogcsdnnetliumangxiongbcache as the Linux kernel block layer cache. It uses the class amp; 20284; SSD as the cache of the HDD hard disk to accelerate the operation. HDD disks are cheaper and have a larger space. SSD is faster but more expensive.

m.2 and SATA3 solid state hard Drive area Don't What do you mean, m.2? M.2 is a new solid-state hard disk interface, is an alternative msata new interface specification, which we used to refer to NGFF, English is all called: Next Generation Form Factor. M.2 Interface SSD The main advantage is that the volume is smaller than the traditional SATA3.0 and mSATA, and the reading speed is faster, which is better for some mobile device compati

2018 Storage Technology Hotspots and trends summary Over the past six months, I have read more than 30 papers and insisted on writing a Newsletter every 1-2 weeks, most of which are related to storage. Here is a summary today for you as a reference to understand the hotspots and trends in storage technology. This article contains new technical areas, such as Open-channel Ssd,machine Learning for Systems, as well as recent developments in the old topi

Solid state storage not only changes the storage industry, but also affects the entire computer field. We have seen that flash memory has completely changed the consumer electronics field, replacing rotating disk drives in almost every category of consumer electronics.This enthusiasm is also extending to the data center. Database Administrators, System administrators, and application system owners have begun to realize the benefits of solid state storage. They see the advantages of solid state s

For work requirements, read some flashcache content and record it as follows: Implementation Flashcache is a new open-source project developed by the Facebook Technical Team. It uses SSD hard disks to cache data to accelerate a MySQL kernel module. We can see that it was initially used for database acceleration, but it was also designed as a general cache module for any application built on Block devices. Working principle. Based on device Mapper,

The benefits of solid-state drives: 　　Benefits 1. Solid State Drives Fastspeed is the biggest advantage of solid-state drives, especially the random read and write speed is hundreds of times times the average hard drive. 　　Benefits 2. Solid-state HDD power consumption is lowerthe maximum power consumption of a common hard disk is about 5-10w, while solid-state drives are usually less than 3W and more environmentally friendly. 　　Benefits 3. Solid State Drive Completely noiselessMany people wil

How to pick a solid state drive? Open a large electric dealer website SSD Solid State hard disk Display page, currently can see 40 different brands. This may confuse many people, how can there be so many brands? To know, the mechanical hard disk market after the brutal competition baptism, currently left several famous brands: Seagate, Western Data (west), Toshiba, Hitachi, which Hitachi has also been acquired by the West. Mechanical hard disk manufa

How to build an Android development environment on a single machine Old saying: to do good deeds, you must first sharpen your tools. To learn about Android development, I lost my blood and changed my computer. As the saying goes, it is a bit paranoid to sharpen the knife without mistake and make good use of the steel on the knife. In order to maximize the potential of the new book, I spent a long time doing configuration and optimization. However, the old saying goes completely correct from the

　　 disk features and application scenarios The disk is divided into local SSD disk and cloud disk, in which the cloud disk is divided into efficient cloud disk, SSD cloud disk and ordinary cloud disk. The following is an introduction to the characteristics and usage scenarios of these disks. High Efficiency cloud Disk SSD Cloud Disk Common Cloud Plate Local

Here's how to use a solid-state drive system and some things to note: 1. Why the need for solid-state hard disk loading system Solid-State hard drive systems can lead to rapid computer performance, especially for day-to-day operations, because the system disk is responsible for the computer's main reading and writing operations. Traditional hard drive due to the internal transmission rate of the problem, read and write speed on average only in 100mb/s, and

With the innovation of storage technology, solid-state hard disk (SSD) plays an increasingly important role in enterprise application. The advantages of SSD performance are obvious compared with traditional hard disk, whether it is read-write or random access speed. But traditional hard drives are mature products that have existed for decades as mainstream storage media and have been supported by a series o

What are the optimization techniques for solid-state drives? Solid-State hard disk is called fixed disk, is a solid-state electronic memory chip array made of hard disk, its chip operating temperature range is very wide, business regulation products (0~70℃) of the product ( -40~85℃). Although the cost is high, but also is gradually popularized to the DIY market. The new generation of solid-state drives generally adopt SATA-2 interface, SATA-3 interface, mSATA interface and Cfast interface. Let

Ceph environment setup (2)1. There are three layout hosts: node1, node2, and node3. Each host has three osdks, as shown in figure. osd1, and 8 are SSD disks, 4 is the SATA disk. Each of the three hosts has a Monitor and an MDS. We use osd1, 3, and 4 to create a pool named ssd, in the form of three copies, osd0, and 2, 4 to build a Pool named sata, in the form of Erasure code, k = 2, m = 1, that is, use two
