Data Flash Memory

The hybrid flash array is superior in performance to an array based on traditional hard drives, with lower latency and cheaper prices than most pure flash arrays. However, their prices are still higher than those based on traditional hard disks, and their structures are much more complex. 　　Given the price and complexity, what kind of applications and environments can derive the most benefit from a hybrid flash array? First, let's look at the purpose of developing a Flash array: High data growth rates have had a huge impact on the data center. Analysis of this problem can start from "3V", namely: Volume (volume) 、...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

Shared Flash array Vendor Violin Memory today announced the launch of 3 new products, compared to existing products, new products in both capacity and performance improvements. The existing 3000 series of products from two 3U rack box, 3200 of the storage capacity of 10TB, the use of Single-stage unit Flash, can provide 220000 continuous write iops;3140 storage capacity of 40TB, using 2-bit multistage unit flash. This is a violin array of products that were available in the market before yesterday. Now, violin launched 3220, single level single ...

Fujitsu's chief technology officer Dr Joseph Reger Flash is just one of our central stations for developing a memory storage architecture--a point that Dr. Joseph Reger, Fujitsu's chief technology officer, recently raised. Flash is facing some unresolved problems, according to Dr. Joseph Reger, chief technology officer of Fujitsu's technology solutions. He says the density of flash memory is increasing, but this is in exchange for the ability to read and write data. With the improvement of manufacturing process, the durability of flash is decreasing inversely, ...

In order to maximize the speed advantage of solid-state storage, more and more vendors are moving flash storage to the CPU that is closer to processing http://www.aliyun.com/zixun/aggregation/17326.html "> Storage data." Stec and OCZ Marvell Group also launched a flash memory device based on the pci-express (PCIe) bus interface last week. STEC Company is the first to enter the market, and launched a ...

Absrtact: With the rapid popularization of mobile phone, digital camera, tablet computer and vehicle navigation equipment, users ' demand for high speed and large capacity memory card is more and more, and Toshiba company, as the founder of Flash World, has been leading the development of storage industry. With the rapid popularization of mobile phones, digital cameras, tablet computers and vehicle navigation devices, the demand for high speed and high-capacity memory cards is increasing, and Toshiba, the creator of Flash memory, has been leading the development of storage industry. Toshiba Electronics (Shanghai) Co., Ltd. was founded in 1996, is responsible for Toshiba Semiconductor devices ...

At present, more and more people are using U disk or mobile hard disk frequently, import and export data between different terminals, such as pictures, movies and music, etc. people begin to want a service that ensures that data is consistent across devices so that the latest data can be invoked on any terminal at any time. Multiple people can also collaborate to edit the same file; It is also recognized that data may be lost when storage devices are lost or updated, and that data is secured if the data is synchronized to a network server. Now cloud storage has become a trend, a fashion, a new life ...

With the industrial revolution, the rapid development of science and technology, people choose the storage medium has also undergone a great change, hard disk began to become People's daily work in the necessary products, and in the data storage plays an important role. But in recent years, because of the popularity of social networking sites and intelligent mobile terminals, the amount of data created by people is staggering, according to statistics in 2013, the total amount of data produced in China has exceeded 0.8ZB (equivalent to 800 million TB), under the pressure of massive data, how will the data storage media change? Enterprises face massive data how to upgrade the traditional data center ...

Lead: US it website CNET wrote today that with the development of cloud computing and virtualization technology, traditional mechanical hard drives have been unable to meet current usage requirements, and faster flash memory will gradually become the main storage market. The following is the full text of the article: Flash memory will become an important part of cloud computing and virtualization, and it is time to discard traditional hard drives. Cloud computing and virtualization have dramatically changed the server infrastructure, but the real push for a recovery in the storage industry is the rise of solid-state drives and flash memory. Flash will continue to bring much-needed impetus to the enterprise sector. From the Fusi ...

Tcl's founder, academician of the American Academy of Engineering, and ACM fellow John Ousterhout are currently teaching at Stanford University, and his main research projects in recent years have been ramcloud--memory clouds. As the name suggests, Ramcloud is such a new data center storage system, which is a large-scale system composed of thousands of ordinary server main memory, at any time, all information is stored in these fast dram (dynamic random access memory, commonly known as memory), Memory replaces the traditional system in the hard drive, the hard drive only ...
