Recently, the kernel program needs to be debugged under Windows, which was always done using WINDBG+VMWARE+VISUALDDK, but it was a pleasure to discover that vs2012,vs2013 could debug the source code level directly in the IDE. A burst of revelry, build the environment, install vs2013 and wdk8.1 (my space has a newer wdk8.1), but has not been too successful, after a day of tossing, finally can be debugged.(the main reference http://www.livecodenote.com/2014/04/vs2013-vmware-%e8%b0%83%e8%af%95%e9%a

The cause of the matter is simple. I am using the tablet Lenovo Helix last year Sea Amoy, because the discount is good, the configuration is not high. SSD is only 128GB. After Windows 10 Push Installation, the SSD remaining space is smaller than a day, even if I often clean up the disk, still always hovering around 20GB. Suddenly one day, space only left 15GB, who suddenly stole my disk space? In my experie

First step : Select "File"--"new virtual machine"Open the New Virtual Machine Wizard-Select Typical (no other advanced options are used for general learning purposes)Configure the virtual machine platform first, so select "Install the operating system later"Choose the corresponding version based on the Linux version and the number of bits you downloaded, and if it's arch and Kali select "Linux, others"Edit "virtual machine name" can be arbitrarily modified easy to manage the name, "location" is

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,

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

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. For details about bcache reprinting, refer to http://blog.csdn.net/liumangxiongbcache. It uses

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,

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

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

certain requirements. It is best to have 16GB of memory on the development machine so that at least 10GB of it can be allocated to the virtual machine. While you can run a SharePoint 2013 virtual machine on a machine with less memory, it's likely to run fast enough to make you mad. In addition, because running virtual machines has certain requirements for disk I/O performance, it is recommended that you place the disk image files of the virtual machi

First step, upload the necessary documents Here after we have installed the Debian environment, and according to the requirements of the need to partition and set the size of the letter, because the old left test this machine only 10GB hard drive, is not well-off so can only reluctantly partition up. Here we need to prepare 3 files, namely maxdos.img (Http://soft.laozuo.org/iso/MAXDOS. IMG), Grub4dos.tar (

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

For many PC users, now use the SSD and the latest WIN10 operating system, but most users use a solid-state drive capacity of 120GB or 240GB, after installing the WIN10 is prone to the problem of smaller C-disk space. For WIN10 C disk space is getting smaller how to do? Today Xiao Win10 teach everyone to thin body small coup, mainly delete some not too useful large files, to effectively release the system C disk resources.1. Delete windows.old filesIf
