and uses shareplex to optimize its performance. Li xuanhui said that fluidcache is suitable for OLTP, ERP, desktop virtualization and other applications with high performance requirements. Fluidcache for DAS is suitable for accelerating a single application, while fluidcache for San is suitable for cluster environments composed of multiple servers and can achieve high-speed access across different servers. On fluidcache, Dell also implements read/write splitting. Pay attention to the following

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are only suitable for laptops or enthusiasts. Of c

Before understanding the basic principle of random access memory, which is mainly through the charge and discharge of the capacitor to ensure the data read and write, when the power loss, the data is lost, this section we mainly learn the basic composition and principle of Flash. Now flash in the embedded system and the status of the hard disk on the PC similar to the system used to save the system, data and application sequence, and memory loss after the power, it can be permanently saved after

The submission form inserts the data with insert into, but always blank, without prompting for an error. Excuse me, is there a problem? @header ("content-type:text/html; Charset=utf-8 "); require_once ' inc/site_config.php '; require_once ' inc/db_connections.php '; require_once ' inc/ Function.php '; mysql_query (' Set character set "UTF8" '); Session_Start (); if ($_request[' action ']== ' Postreg ') {$sql _check_usr= "select * from ' Reguser ' where ' UserId ' = '". $_ session[' uid ']

If you want to keep some of the data to a U disk, then you have to consider the life of U disk, U disk storage environment, temperature, humidity, etc. will be a U disk to a certain life effect, there is a general U disk is the use of the term is wiped 30000-10000 times. The general use of MLC particles of u disk can be erased more than 10,000 times, and the use of SLC particles of U Disk Service life is up to 100,000 times. If your data is stored for

flash memory, so the price of SSDs is also higher. Take the same 1TB capacity as an example, the traditional mechanical hard disk is only about 800 yuan, and SSD needs at least 2000 yuan. So, what is the read-write life of SSD solid-state drives? There are also two parts to be divided. SSD flash particles are usually two particles of SLC and MLC, whereas SLC can read and write about 100,000 times and MLC

characteristics: 1, the speed is slow, the market share is very high. 2, the quality of flash chip is very poor, basic is the use of black film. 3, JS are like sales, because the price is low. Flash manufacturers do not need to compare, Samsung, Intel, Heidelberg, Toshiba are manufacturers. But there are SLC, MLC, TLC points. SLC (Single-level Cell) is 1bit/cell, the speed of long life, the price is e

In previous projects, we understood the wear and loss balance of flash memory, and manufacturers were looking for the cause of the loss around the way they worked. The technology used by the supplier to solve the wear problem aims to make the solid-state hard disk based on flash more predictable, although the implementation is still long, but predictability is the key to the firm's reliance on solid state storage. There is another key factor that affects the storage life of solid-state hard disk

the parameters of SSD, will be labeled with SSD read and write speed, some marked is the average, some marked is the maximum read and write speed, we can through the average and the maximum value to do a comprehensive reference, the larger the number, SSD solid state hard disk performance is better. Three, solid state hard disk particles In the solid state drive parameters, there are also particles, solid-state hard disk particles have three types, respectively,

number of packets in the network at the same time is constant. Only when the "old" packet leaves the network can a "new" packet be sent to the network.. (If the sender receives a duplicate ack, the tcp ack Mechanism indicates that a packet has left the network, so cwnd increments ). Quick recovery steps: 1. When three duplicate ACK packets are received, set ssthresh to half of cwnd, set cwnd to ssthresh + 3, and re-transmit the lost packets. 2. When a duplicate Ack is received, the congestion w

of TCP vegas, it uses network delay for congestion determination. ECN: Explicit Congestion Notification. The idea of this algorithm is to use vro. When a vro detects congestion, it marks the congestion in the TCP or IP address header of the connection, allowing the terminal to handle the congestion by itself. UDT: UDT is an open source reliable transmission protocol based on UDP. However, the congestion algorithm in UDT has nothing to do with UDP or TCP. UDT uses a bandwidth estimation algorith

A few days ago, I downloaded a large file upload example on 51aspx .. I tried it .. it takes only 50 seconds for a 119 M object. I was still thinking about it. study hard. then write a normal upload example and compare it. just modified the configuration file. I tested 119 M and it was also 50 seconds .. only then can we find that this example is truly confusing...CodeTens of thousands of lines are written. How to set all. the upload status does not improve the upload efficiency... Multi-File

The wm8994 debugging was successful in the past two weeks, except for frequent codec exceptions caused by the unstable start of the ldos. I have to lament that sometimes the size of a resistance affects the entire system. You should pay attention to it as a hardware engineer. Wolfson's engineers are also nice. They can answer all my feedback in a timely manner. Thank you. Below we will record several major problems. As for some trivial issues, such as the absence of some mixer controls (MIC bias
