The company's ERP system has a large amount of data, with 40 GB of data and 90 + concurrent users and 1000 + connections. The original IO performance cannot meet users' operation response requirements, and report query is slow, all the indexes have been done, and the index is re-built once a week, but the problem still cannot be solved. To this end, the company purchased the dell poweredge R720xd server, which supports two arrays and 24 hard disks, dual-CPU, 64 GB memory, more awesome. We have c

How to adjust the boot sequence of SSD after installing solid state hard disk in computer
1, after the computer restart, point del into the motherboard interface, go to boot, you can see the start of the sequence of display;
2, the problem is not seen in the startup preferences of solid-state drives, and then enter hard disk Drive BBS priorities;
3, in the choice of the inside can see solid state hard drive and mechanical hard dri
To the introduction of solid-state drives, compared to the old mechanical hard drive, SSD solid state hard disk is said to be the same as the rocket speed, the installation of solid state hard drive after the Win7 system, whether the boot or operation has a quality upgrade, but many friends may not know, the use of solid-state drives there are some need to know the optimization methods, Allows your solid-state drives to perform optimally in Win7 syste
Sometimes the read/write speed of the OS reduces the performance of the MySQL server, especially when the OS and MySQL use the same disk. Therefore, it is better to make MySQL use a separate disk and use SSD. To achieve

Select the SSD attention and purchase skills sorted out to the small white user for reference, and Samsung 300e5k to replace the SSD process as an example for everyone real machine demo.
Before you decide to upgrade SSDs, you first need to evaluate whether your computer is suitable for SSD installation. Here need to explain, not that

ObjectiveBecause the mechanical hard disk (HDD) on the notebook has already installed the WIN10. Although previously installed 128G SSD but afraid of WIN10 system occupied space is too large to do system migration, so some time SSD only do entertainment with ... Now because of the need for work and learning, I intend to install a Linux system on a solid state drive (SSD
share with you the key points of three settings for SSD drives
The key to opening AHCI is:
AHCI, all called Serial ATA Advanced Host Controller Interface (serial ATA Advanced Master Interface)
The potential acceleration capability of SATA drives, which can increase the read/write speed of 30% hard disk. When installing a solid-state drive, turn on AHCI to give full play to hard drive performance.
The current mainstream motherboards are
Because recently want to try a cow break the target detection algorithm SSD. As a matter of fact, I have made thousands of data (actually only hundreds of, using data expansion algorithms such as mirroring, noise, cutting, rotation, etc. to expand to thousands of, actually still is not enough). So on the Internet to find the relevant introduction, their own processing of data into the VOC data set format, in the conversion to XML format and so on. Her
MySQL Enable SSD storage Chszs, All rights reserved, without consent, not reproduced. Blogger Home: Http://blog.csdn.net/chszsSometimes OS read-write slows down the performance of the MySQL server, especially when the OS uses the same disk as MySQL. So it's best to let MySQL use a separate disk, to use SSDs better. To do this, you need to mount the SSD new disk to the server, assuming the new disk is/dev/sd
This paper introduces the preparation, transformation and the whole process of using SSD to train the data set in target detection. Contents include:
1, Data set preparation
1) Image callout
2) make VOC DataSet
3) Convert VOC data set to LMDB format
2, how to use SSD for training
3, use SSD to do test environment: Win7, compiled Caffe, P

What should I do if the system runs fast? Group raid? Ssd solid state drive? No, these are all tricks. The method to be introduced today is almost ready for windows xp to be started in an instant. Opening the program is like flying-it is to load windows xp into the memory!
First, you have to have enough memory to accommodate Windows XP, and now the memory is not expensive, 2 GB is enough. I directly used 4 GB, 32-bit system can use m

No Zuo no die, which is not upgraded to Yosemite, and then found that trim activated in mavericks is not working here, and prompts that trim enable is not suitable for this version.
Then, the tragedy began. I found an old post and changed the kernel file according to the command. It was not suitable for Yosemite. Then I restarted the file and couldn't get in...
A prohibited logo is everywhere, so it's cool. I haven't even done mavericks's USB flash drive installation disk yet. I can't even drop

Many of the new friends, long ago for their love machine with the SSD, enjoy it brings the speed of response and program load, and for some old computers, upgrade SSD can significantly improve the efficiency of the machine, but also more investment than the replacement of other accessories relatively low. However, for most ordinary users, it is natural to upgrade the lower the better, in a limited budget, i
