In order to export the words accumulated in youdao dictionary and then import them to another English learning software named 91, the format exported from youdao dictionary is different from that required by 91 English language software, you must adjust the settings before importing data. For this reason, I spent half a day studying the word replacement function, especially the use of wildcard characters. For example:
Youdao export format:

The quality assurance of the hard disk, this is a problem that almost all people have to consider when buying things. Hard work is always running at a high speed, and the hard drive is actually very fragile things, no one wants all of their important data easily to ashes. In the domestic, for the hard disk after-sales service and quality assurance in this respect, each manufacturer is also good, especially the boxed brands also prov

What if the laptop fan doesn't turn?
Generally speaking, the notebook after a long time, the notebook CPU fan inside easily accumulate a lot of dust, so it is easy to cause the fan due to the accumulation of dust too much, causing the fan does not turn, this situation is also very common.
Solution: If the computer is still under

Each server

of the data center is redefined, rather than storage. But now so-called hyper-convergence, although the emphasis is on the data center computing, storage and network integration, but in my opinion also fused the computing and storage parts.

for some scenarios, such as virtual machine active image storage, or virtual machine hard disk file storage, as well as large data processing and other scenarios, object storage is stretched. The file system has outstanding performance in these areas, such as Nutanix's NDFs (Nutanix distributed Filesystem) and VMware's Vmfs (VMware Filesystem) perform well in virtual machine image storage, Google File System GFs and its open source implementation HDFs
at present, the "Hyper-integration scheme" is better, the traditional data center gradually transition to the new data center, so-called traditional data center HDDC refers to the data center superimposed by the hardware resources, and the new data center SDDC refers to the software-defined data center, Mainly refers to software-defined computing, software-defined storage and software-defined networks, the pursuit of a set of data center software to achieve centralized management and control of

The first solution is typically a data center rack: Companies involved in virtualization combine to create a pre-built and tested hardware platform that is supported by a single vendor. The most famous of these solutions may be the Vblock provided by Cisco, EMC, and VMware, but other companies have taken action, as Dell offers Vstart solutions.
