Solution: Many of the problems encountered by users using EMC storage are host-related, such as the inability of the host to access back-end disks, a large number of LUN transitions (lun trespass), sudden slow performance of access storage, and so on. By running a software tool on the host, EMC report or

On the 122th page of the foundation for Artificial intelligence, the author presents a simple semantic network and a first-order predicate representation of the semantic network, which describes a method of storing predicates as columns of data tables. But there is a problem with t

When an administrator first starts using the Docker container, it is often surprising that the container itself takes a non-persistent storage. When the container is removed, the container's storage is also removed. Of course, if there is no way to implement permanent storage, the use of container applications will be very limited. Fortunately, some methods can i
