Design division, Knut Grimsrud said the SATA3.0 transmission rate was 6Gbps.
Now seven years later, the speed of solid-state hard disk has changed dramatically, many excellent SSD read and write speed has reached 550mb/s, this is already the limit speed of SATA3 interface, so many manufacturers choose to develop new interface solid-state hard disk.

SAS 8408E, which optimizes raid performance with high-performance Intel I/O processors and increases bandwidth through the Pci-express host interface, provides an intelligent and robust raid solution. In addition, this adapter supports 256MB DDRII SDRAM for data caching and supports the smart Portable battery backup module (ITBBU), which saves cached data under a 72-hour full power outage. The portable caching module can even be moved to a new MegaRAID adapter, while preserving the full
I believe that the AVADirect mini game PC has a general understanding of the following for you to share an article, the relevant industry to carry out a specific analysis and evaluation of the article.
Overview article
For SFF (minicomputer), chassis design is particularly important, so AVADirect chose BitFenix prodigy Fire Bird MINI-ITX chassis. In the following article we will give a detailed description of it, the present first to tell you about

5. 2 Cabling Intelligent Management System content
In the prophase construction and operation Maintenance management of the integrated wiring, the data and information related to the wiring system mainly include:
(1) Equipment and cable use, use of departments, LAN topology, information transmission rate, terminal equipment configuration status.
(2) Hardware number, col
. Hardware DesignThe hardware connection of the MCP2515 and s3c2416 is shown in Figure 3. If the hardware schematic diagram shows that the MCP2515 chip is connected to the s3c2416 chip SPI0, interrupted on GPF1, MCP2515 output connection sn65hvd230 can bus transceiver, sn65hvd230 is Texas Instruments produced by the 3.3V can transceiver. In order to save power and reduce the circuit volume, the logic level
ADSL Cat LED Description
ADSL Cat indicator is an important tool to judge ADSL faults. Different brands of different models of cat led numbers vary. But they all have link lights, LAN lights and power lights.
Link Light Status Description
Link lamp for the cat and the local Dslam device connection indicator, usually link lights have a rhythm flashing, indicating ADSL data link is trying to sync, at this time the link is not connected. Under normal circumstances, ADSL cat after a minute of syn
The new version of Eggplant Express Computer version has increased the classic two transceiver mode, in this mode, in addition to supporting the file with the Android device to send and receive, while also supporting the computer (Windows system) and computer (Windows system) between the file transceiver, computer (Windows system) Send and receive files between iOS devices (note: Only pictures and music are
this time the link is not connected. Under normal circumstances, ADSL cat after a minute of synchronization process, after the success of the link lights often bright, some brand model cat link lamp has the role of the data transceiver led, will be flashing with data transmission.
In the Internet, if the link lamp has a rhythm flashing, indicating that ADSL is not synchronized, then the network is in a state of interruption, in most cases, there is
standard for applications that have a frequency range between 2G to 10G Hertz. We can see that 802.16.1 is responsible for very high frequencies, and its work is at the forefront of these three groups. Because of its unique bandwidth, 802.16.1 is most likely to attract industry interest in the future. The role of the 802.16 wireless service is to establish a communication path between the user site and the core network, which can be a public telephone network or an Internet. The IEEE 802.16 s
worker thread (recall how the Java program is executed in the Tomcat thread, how the task is performed in the Dubbo worker thread), As a result, you can increase the number of worker threads by increasing the concurrency capability, and the main focus today is "how much of this model worker thread is set to maximum concurrency".Pure Asynchronous Threading ModelThere is no blocking anywhere, this threading model only needs to set a very small number of threads to achieve very high throughput, LI
IO transceiver function, the specific IO transceiver function and the use of the event model and operating system related;Assign a socket address (SOCKADDR), and copy the Accept to the end of the address, and save it in the Sockaddr field;Save the local socket address in the LOCAL_SOCKADDR field because the value is available from the listening structure ngx_listening_t, and the listener structure holds on

IntroductionTraditional manual Office is unable to meet the needs of modern office, transceiver management system as to improve work efficiency, standardize Office system, enhance the transparency of office, realize the unified management of information and document resources, facilitate leadership decision-making, and gradually realize the paperless office of important tools, more and more people pay attention to.

Help coal mine customers adjusted for many years terminal resistance, summed up some of the experience for everyone to reference, no reference theory, but are the result of practice.
About the terminal resistor: We always remember can terminal to add 120 euro, but that is a short distance impedance matching results, if in the long-distance or add 120 kohm will be very harmful to the signal, because the can transceiver drive capacity is certain, trans
interface is also a two-wire interface, it is two lines through a complex logical relationship between the transmission of data, communication speed is not high, the program is also more complex to write. The general SCM system is mainly used to connect with small easy memory such as 24C02.SPI: High-speed synchronous serial port. All-in-line interface, independent transceiver, can be synchronizedUART: Universal asynchronous serial port. Two-way commu
the network port, from the SD card, start the application, the whole transplant process is smooth, unexpected smooth, I drop off the bottom transceiver function after the transplant, soon can use, but I am not satisfied with the "official boot" Serial transceiver is a blocking way, as if very backward, I use the LPC1788 on the non-blocking mode of receiving and sending. However, the official boot function
is high, and in the use of the process will inevitably bump, therefore, in the use of a certain period of time, the test of the performance of the mobile phone transceiver will appear to varying degrees of decline. Under the same test conditions, the test results for the use of the new mobile phone and the old one are likely to differ significantly, which will result in a different assessment if the assessment requirements are severe. When the DT roa

In the whole optical network, the backbone of the network generally uses quartz fiber network equipment to ensure the transmission distance. and between the Working Group and the workgroup, between the Working Group and the user, uses the plastic optical fiber equipment, realizes entire local area network uses the light to transmit the information.
