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
hardy Architect Technical Alliance The all FLASH/SSD storage trend is unstoppable, as is the case with NAS services in the future, with a number of startups supporting all-SSD NAS storage services, including EMC Isilion, all-flash nodes.High IOPS capability under

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

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
The storage market has been stable for many years, and the top six vendors in the market are stable. However, in recent years, with flash memory becoming the biggest innovation point in the storage field, A large number of storage start-ups have started to rise and attracted the attention of a large amount of capital.
Fault Description:A hospital in Beijing EMC FC AX-4 storage crashes, due to the failure of 2 hard drives in the RAID5 array, when only one hot spare is successfully activated, resulting in the RAID5 array paralysis, the upper LUN is not working properly, the entire storage space consists of 12 1TB stat of hard disk, Of these, 10 drives form a RAID5 array, and the
