Co-state throttling (Ac-connected inductor)
In the filter circuit, the common mode Throttling is connected in series on the FireWire (L) and Neutral Line (n) to eliminate online low-pass common state and RF noise of power supply. Some power supply input lines will be wound around the core design, can also be considered as a simple co-state throttling.

Due to the lack of some key features, reliability has not been tested for a long time, it is not suitable for the need to provide 24-hour uninterrupted service product environment. Currently suitable for the use of large data offline applications, let's look at the Glusterfs Distributed File system installation configuration

being unavailable, a phenomenon known as service avalanche effect. The service avalanche effect is a process in which the service consumer is not available and will not be usable due to the unavailability of the service provider.As shown in: A as a service provider, B is a service consumer, C and D are service consumers of B. A unavailability causes the unavailability of B and will not be available as a snowball to C and D, the avalanche effect is formed.In this case, the whole service is requi

To use the Distributed file system to reduce costs, we searched for open source Distributed file systems. After the installation of deployment and testing, I encountered in the use of some of the problems summed up, I hope to help you, I also have some problems do not understand, I hope to communicate with you, and common progress.

I searched for some materials on the Internet, saying that CEpH has the highest performance, C ++ compiled code, supports

Sometimes it was unsuccessful to use the download tool and related software to burn and write the fuse, this can easily cause the chip to be "decommissioned ". I did not test the firmware of each version of usb isp and the host computer progra

CentOS6.3 Mount Read/Write NTFS partition (NTFS-3G) CentOS is not like Fedora, by default is not automatically mounted NTFS, and it can use NTFS-3G to achieve mount and read/write. NTFS-3G is an open source software that can realize NTFS read and write support in Linux, Free BSD, Mac OSX, NetBSD and Haiku operating systems. It can read and write NTFS partitions in Windows safely and quickly without worrying about data loss.
