large number of IO wait. But I already said at the beginning that the machines in the cluster have the same configuration and the deployed programs have the same rsync as before. Is the hard disk broken? I have to check the problem with the O M personnel. The final conclusion is: Sdb is a dual-disk RAID 1 with a RAID card of "LSI Logic/Symbios Logic SAS1068E" and no cache. Nearly 400 of IOPS has reached the hardware limit. The raid cards used by oth

Disk array is a long-standing technology on the server, it is widely used by most server OEMs to make reasonable use of space and performance in different array modes to match the cost-effective disk array. Among them, LSI Company's MegaRAID SAS products are widely used in various brands (except HP) x86 servers.Why is there a cache?Array Card core technology consists of three parts: 1, Data stripe, 2, data
