reach bits, but the working method is different from the single-channel memory control technology of bits. Because the two memory controllers in the dual-channel system are independent and complementary Intelligent Memory controllers, both memory controllers can operate at the same time without waiting for each other. For example, when controller B is preparing for the next access to the memory, Controller A reads/writes the primary memory, and vice versa. This complementary "nature" of the two

High-performance storage layer on top of the Low-performance storage layer As the ecosystem continues to evolve, this series of products will be integrated into many other systems in the future. What is the product size? Half-height md2 PCIe insertion card What modes does this product support? This series of products can be used as an extension of persistent storage mapped directly to hosts (random small access can achieve tens of millions of iops ), it can also be used as an n

the memory controller and the DDR3 memory module is a point-to-point relationship, or point to the two-point relationship, thereby greatly reducing the address/command/control and data bus load. In the memory module, similar to the DDR2 category, there are standard DIMMs, So-dimm/micro-dimm, fb-dimm2, where the second-generation FB-DIMM will adopt a higher-speci

) Relationship (dual physical bank module), thus greatly reducing the load of address/command/control and data bus. In memory modules, similar to the DDR2 category, there are standard DIMMs (desktop pcs), So-dimm/micro-dimm (laptops), fb-dimm2 (servers), where the second generation of FB-DIMM will adopt a higher-specification AMB2 (Advanced memory buffers )。 DDR

The dual-channel memory technology is actually a kind of memory control and management technology. It depends on the memory controller of the chipset. Theoretically, it can double the bandwidth provided by the two memory of the same specification. It has long been used in servers and workstation systems, but it has come to the technical front-end to solve the increasingly embarrassing Bandwidth bottleneck of desktops. Dual-channel memory installation has a lot of attention. For boards using i865

Length measurementA test technique called TDR (Time Domain reflection measurement) was used to measure the length of copper cables. The tester emits a pulse wave from one end of the coppe

In addition to the three variables, I would also like to discuss the special variable arguments, which is slightly different from Function. prototype. arguments (discarded.

of an application with different browsers on different devices, because it is too costly to establish a lab and deploy human resources without a large number of devices. Crowdsourcing testing activities can help to cope with certain difficulties, such as getting users from different places and testing versatility on multiple devices. Crowdsourcing testing has been gaining momentum recently because the value produced by groups can be achieved by an internal testing team. Group testing cannot rep

in this particular network environment. The network standard defines the end-to-end connection specifications for the cable medium used in the network. Network standards are especially useful when you need to know whether a network fault is caused by a cable. Currently, most common networks run at 10 Mbps. 650 or 652 of existing low-price cable testers, such as Fluke, is used to test whether these cables comply with network standards. These cable testers provide automated testing capabilities t

1. When do testers need to participate in requirement analysis? In principle, the deeper the tester understands the requirements, the more favorable the testing work. Therefore, it is best to participate in the requirement analysis work from the very beginning. This can bring the following benefits: Testers participate in the demand analysis throughout the process and have a deep understanding of the requirements, which reduces the interaction with de

Testing Instruments and testing standards Before testing, we need to select appropriate testing instruments and testing standards. Generally, we use internationally recognized testers for testing. For example, when testing copper cables, we use a cable test table for basic connectivity (on) testing. When testing Category 5 lines, we used the Mi

Sympathy tests during product development: Therefore, tests during product development should not be blunt. In fact, at this time, the program staff also know that the product is not mature, so they should tell the test execution staff: ● Do not submit simple UI errors or usability bugs at this stage (you can record them and submit them at the end of the project). Otherwise, developers may question the tester and only find simple bugs. ● Empathy, unde

So how to master the quality of these media to ensure unimpeded transmission of information, it is necessary to rely on cable testing equipment verification. In addition, in the cause of network failure, more than 90% of the fault is due to cable link problems, but these problems are not only visual or multimeter can be in the shortest possible time to check out. In the process of building the network, we must pay attention to the use of the normal cable tes
