Data compression technology boosts the network copy speed of the protection card 100M environment to exceed 1G!
The computer room is responsible for the important tasks of teaching and experimenting with various courses in the school. How to quickly and efficiently deploy the computer room's computer environment is one of the important job responsibilities of the computer room administrator. At present, the deployment of computer room software environment is generally achieved through the network copy function of the hard disk protection card. As we all know, in the case of data copying in a 100M network environment, the theoretical maximum speed that can be achieved is 750M / min, but in practical applications, due to technical limitations and various losses, the speed that can be achieved is generally 400-600M / Minutes, such data transmission speed is far from meeting the needs of rapid deployment of large amounts of data in the school computer room at this stage.
So, is there a technology that can break through the barrier of 750M 100M network copy speed? The answer is of course yes!
We recently learned from Wuhan Oiyi Technology Co., Ltd., which specializes in R & D and production of computer room maintenance products, that the company ’s R & D department has spent six months of intensive research and development and successfully implemented the upper layer differential copy operation mode based on the Windows system environment The network copy speed of 100M environment exceeded 1G! After the field test in the school computer room, the stable value of the copy speed is 1.2G / minute, and the fastest can reach 3.5G / minute!
According to the company's director of research and development, the current data copy of computer room maintenance products are generally based on the Dos operating system environment, and Dos is a 16-bit operating system. In the 16-bit operating system, the important hardware for the data copy process- -The network card driver (NDIS driver and packet driver) is not efficient, and only supports single task sequencing during transmission, and the memory utilization rate of the computer itself is relatively small, so the copy speed can only reach 400-600M in a 100M network environment. /minute. The research and development staff of Wuhan Oiyi Technology has innovatively ported the data copy function to the Windows operating system, which is in a 32-bit operating system environment. It is extremely efficient for the network card driver (network card driver under Windows), and supports multi-task synchronization. The utilization of computer memory is maximized, so its copy speed breaks through the theoretical barrier of 750M / min in one fell swoop, reaching more than 1G / min!
In addition, on the basis of data copying based on the Windows operating system environment, the research and development personnel of Ohi Technology also used a multi-level compression mechanism, that is, multi-level high-strength compression when reading hard disk data, and when writing data to the hard disk Perform hierarchical decompression, which will further increase the speed of data copying. In the case of a good network environment and a high hard disk speed (which affects the reading speed of data), the peak speed of data copying can even reach 3.5G / minute.
At present, Wuhan Oiyi Technology has successfully applied this technology to its two series of products, Oiyi Computer Room BOSS System and Oiyi Free Card.
