Intel has recently been exerting its power at the channel end, and the computer stores, 3C stores and the manufacturers of the manufacturers have been pushing the pole. However, in the face of "super extreme" this jerky vocabulary, a large number of users do not understand their meaning. Many consumers think "ultra-extreme" means super lightweight and super performance. There are many consumers do not understand the use of expensive SSD, there are a l

(generally four months after the software is delivered to the user for the accidental failure period. Generally, the number of failures per 1000 hours indicates the quality of the software in a stable State. D. Average time before expiration (MTTF)The average statistical time of normal software operation before the failure. E. Average failure interval (MTBF)The average statistical time for normal operation of the software between two successive failu

from a technical point of view, NAND Flash Flash Media Although there is a problem of the number of erase times, but with software algorithms, system-level data protection technology,NAND flash life is no longer a difficult problem, and NAND flash More advantages have become an important driving force for the technology to move forward. SSDs built with NAND Flash are rapidly replacing traditional disks, have been widely used in the Internet, and continue to penetrate into the enterprise-class m

which AZ the user can guarantee high reliability by creating virtual machines in multiple AZ.Haz also divides a batch of compute nodes with a common attribute into the same Zone, which can be further subdivided into AZ, an AZ can have multiple HAZ. machines in the same HAZ have some common properties, such as high-performance computing, high-performance storage (SSD), high-performance networking (Sriov support, etc.). The other difference between Ha

Bcache is the Linux kernel block layer cache. It uses 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. If you can have both of them, isn't it easy? Bcache can do this. Bcache uses SSD as the cache for other Block devices. Similar to the L2Arc of ZFS, bcache also add

7200RPM mechanical hard disk, also added a 2G memory, let it serve 2 years. According to the "Moore's Law" of integrated circuit components every 18-24 months to increase the number of times, performance will be nearly one more times, my "little black" is almost three times times the mainstream of the market. And now a variety of software volume and the hardware operating environment required space resources is also more and more high (those software manufacturers, you do not think the hardware

With the popularization of SSD solid-state drives, now with the cache of SSD prices are gradually accepted by users, although we know that there is no cache of SSD in the price will be slightly more expensive than the cache, but the cache on the SSD solid state hard drive how the role played by not every user is aware.

Yesterday I helped a colleague install a Samsung computer, which gave me a new understanding of system installation, Record this and hope to help you. As a computer enthusiast, installation is a required skill and a source of confidence that reflects your own abilities or understanding computers. Model:

Pukot px-128m6s (m6s series) 128GB Reference Price: 419 RMB Pukot solid-state hard disk in the industry has a very good reputation, belong to the first-line SSD brand camp. Today for you to recommend the first 120GB-128GB SSD is today recommended 6 of the most expensive products, but the comprehensive performance of this product is undoubtedly the most prominent. This Pukot px-128m6s solid-state drive is s

of load determine that all storage devices must have the highest possible performance to cope. The ideal goal is that both types of load can achieve the same performance as the top-level memory in Figure 2. At the same time, it is also expected that it has a non-volatile external memory as shown in the bottom layer of the figure to make up for the problem that data is easy to lose when there is a power failure in the inner. From the memory to the external storage level, we can see that the idea

Last Saturday, I attended a Baidu technology Salon held by infoq. The topic is about MySQL. There were a lot of people present on that day. Some of them were unexpected, maybe because they were free of charge :) There are two speakers, the first from Baidu, who mainly introduced Baidu's work on SSD/flash and the second from terradata. The topic is about spatial database. Frankly speaking, the first speech was very good. We can see that Baidu has done

What is a solid-state drive? How do you use it? Correct use of solid-state hard disk method Guess what you like: the difference between m.2 and SATA3 SSD In general, the proper use of solid-state drives is nothing more than 4K alignment and the ability to turn on the hard drive AHCI. In addition there are a few people will not notice the details, the previous article has not been detailed with you, the following article to explain in detail under

in 2015 years, TLC SSD has gradually become the market leading role, with the ultra-high cost performance of the SSDs launched a popular campaign. In the TLCSSD Gongchenglvede, many SSD companies began to play "EMLC", and TLC SSD Camp also appeared "ETLC" branch. So what exactly are these prefixes with "e" flash particles? Here's a chat about the difference betwe

NVMe SSDs are the evolution direction of storage disks, and NVMe SSDs have more than ten times the performance growth compared to SATA/SASSSD. This is mainly due to the NVMe SSD Multi-queue technology, through the multi-queue technology can be IO access parallelization, so as to improve the overall performance of the system. in theNVMein the storage ecosystem,Ssdstechnology has become very mature.

The following describes the Linux clusterFirst, the Linux cluster Foundation1. Linux cluster type: LB, HA, HP, DS(1), LB: Load Balancing clusterDefect: A single point of failure, its scheduler can become a performance bottleneck(2), HA: High Availability ClusterMean time between failures (MTBF), mean time to repair (MTTR).RMS ==mtbf/(mtbf+mttr)-------------Increa

the scheduler becomes a performance bottleneck; Ha is known as a highly available cluster, where MTBF (mean time to failure) and MTTR (mean time to repair) and availability=mtbf/(MTBF+MTTR) are the concept, and once we tend to make MTTR time 0, Cluster high availability will be good, for different business, the availability requirements are different, generally

open source software enterprises. The probability of failure not occurring: R (x/t) = exp {-[m (t + x)-M (t)]}R (x/t) indicates the probability that the software will not fail in a given interval (t,t+x). MTTF (Mean time to Failure, mean time-to-failure), which is the average duration of the system's failure-free operation, taking all the average of the time period between the start of the system's normal operation and the occurrence of the failure.
