Rebirth of the Richest Man In Black Technology

Feng Hao didn't care about the dormitory matter, it was nothing but the emotion and amazement of the classmates.

On April 1st, he can now complete the task of system release.

View the system panel.

schedule:. 】

This task has already started seventeen, and there is still one last professional book left, and Feng Hao has also read part of it.

This book is "Flash Design Technology" about flash memory design abroad.

Flash memory has incomparably superior characteristics than traditional storage media and can be stored quickly. Foreign countries have entered the third generation of flash memory NAND, while domestic ones have not yet started.

It is said that in 2005, the sales of flash memory in the whole world has reached 17.5 billion US dollars, and the demand for flash memory is also huge, especially for mobile devices such as mp4, video cameras, and pads.

This book introduces four design patterns of flash memory. The first one is pcie flash memory card. The flash memory method of this mode is the way of moving in blocks, and the storage model cannot be shared. Both the server and the client must be equipped with flash memory cards. CPU performance requirements are very high.

The second is to build storage arrays from flash, shared storage targets on san.

The third is to act as a write-through cache device that offloads the nas or file server at the same time as a file server.

The fourth is the nfs accelerated device, in this design pattern, the flash memory is used as cache, not storage.

crackle!

crackle!

A bottle of Super Coke and a bottle of Super Sprite were opened by Feng Hao one by one.

Gollum, gollum.

Lifting his head slightly, Feng Hao drank the Sprite and Coke that he systematically drew out.

Whoo, whoo!

How cool! Yep, that's how it feels!

At this time, Feng Hao finished drinking Coke and Sprite, and shivered for a while.

His concentration and thinking ability instantly exploded by n levels.

When he opened the page, Feng Hao read it seriously.

Feng Hao carefully absorbed the knowledge in this book, especially his understanding of design patterns.

Two hours later, that special feeling disappeared, and Feng Hao shook his neck without any hesitation.

In the past two hours, he read a lot of content, and also absorbed the technical essence of flash memory.

continue!

After looking at the book in his hand, Feng Hao secretly said.

This flash memory design book has been almost read by him, and it still has less than 30 pages. It is only afternoon, and he still has time!

crackle, crackle!

Feng Hao opened a bottle of Coke and a bottle of Sprite this time.

He estimated that in about half an hour, he could read the rest of the content.

Lifting his head slightly, Feng Hao finished drinking the Sprite and Coke in his hands.

Looking carefully at the book in his hand, Feng Hao was unaware of the passage of time.

When he turned to the last page, Feng Hao felt that he was still unfinished.

It's over!

"Ding, complete the task of storage technology and get an advanced lottery ticket*1, please check it."

"Ding, experience value +750."

"Ding, exchange bonus points +1, current exchange points: 22."

After three consecutive notifications, Feng Hao quickly received a prompt to complete the task.

Feng Hao was looking at the system panel at this time, and a burst of golden light suddenly flashed.

Then, he heard a loud system sound.

"Ding, congratulations to the host's level upgrade to lv21!"

"Ding, congratulations on being promoted to an intermediate programmer!"

"Ding, in view of the upgrade of the host's level, the system has acquired new features, completing different tasks to obtain corresponding points, and opening the exchange store function at the same time."

Level 21, Intermediate Programmer!

Feng Hao first checked the system level, which is his current level.

The corresponding level experience has increased to a certain extent, and the current level is [level: lv21:]

The system panel has been changed. On the basis of the original one, there is an additional store button.

The way of obtaining points has also changed. Instead of only getting one point every time you complete a task, you will get different points according to the difficulty.

This is a good thing!

Feng Hao secretly thought and guessed that it should be easier to get points in the future.

With a secret cry, he opened the exchange.

In a flash, a series of commodities appeared on the virtual system interface.

Battery category: Lithium battery technology (10 points for exchange), super battery technology (50 points for exchange)

Storage category: Flash memory technology (5 points for exchange), ultra-fast flash memory technology (30 points for exchange) \u003c chip design (20 points for exchange), 16mm chip design (150 points for exchange)

Software category: primary source code of intelligent system (20 exchange points), advanced source code of intelligent system (unlocked)

Special Items: Coke (1 redemption point), Sprite (1 redemption point), Beginner Fitness Fluid (10 redemption points), Ultimate Fitness Fluid (unlocked)

Note: Due to permission issues, only some exchange items are currently open and displayed. If more exchange items need to be opened, please upgrade the host as soon as possible to increase the exchange authority.

What the hell!

It's all good stuff!

Feng Hao looked at the related technologies of logic and the introduction to it.

Extremely fast flash memory technology (30 points exchanged), introduction: The newly developed special storage mode, based on the technology developed by sssnvmessd, compared with the traditional stat storage medium, the delay is reduced by 100%, and the performance is improved by 2 times. In addition, the transmission protocol stack has also been optimized twice, and the overall architecture level has also been optimized.

Niubi!

Feng Hao has been researching flash memory technology recently, and naturally knows several aspects of flash memory performance improvement.

The first is the transmission speed of the medium. The better the medium, the faster the transmission.

The second is the overhead-delay ratio of the software stack in the system, that is, the overhead of cpu (chip) reading.

The third is the network delay and transport protocol stack.

The fourth is the overall architectural level.

The stat hard disk is a more traditional storage medium. The actual read and write rate of the sata hard disk is 250mbs and the bandwidth is 6gbs.

If you follow the introduction of ultra-fast flash memory technology, its performance will be improved a lot. Taken together, the read and write speed may reach 1024ms, the bandwidth is 20gs, and the read and write speed will be increased by four times.

To use an inappropriate analogy, Feng Hao is currently using the windosxp system and the stat hard disk, and it takes 60 seconds to boot. But using a hard drive with extremely fast flash memory, it may take more than ten seconds to boot.

Of course, all this has to be developed to know the actual effect.

That's it!

Extremely fast flash memory technology, this is the first item Feng Hao decided to exchange.
