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

How does the world's largest information storage enterprise view the "cloud" era, and EMC Greater China President Ye Chenghui will tell you: "Cloud is not a dangerous thing, but a paradise of information security, but also a learning to save money." ” This morning, at the 2009 Annual Conference on Information Services innovation, Ye Chenghui not forget to use old-fashioned information asset management to a

Recently, the company has been experiencing a full pool of EMC storage pools, resulting in the need to remove LUNs from VMware to free up storage space, documenting this process for later learning.First, the idea of storage removal from VMware is to remove the LUN from the VMware plane, remove the LUN from the host gro

predicate representation, so it has the "EMC-CBR Fault Diagnosis Research (i.)" The results in a paper. But how is the first-order predicate logic stored in the database? 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
