and write disk can be imagined. Therefore, the disk I/O is generally considered to be one of the biggest constraints on MySQL performance, for the average daily access to more than 1 million PV discuz! forum, due to disk I/O constraints, MySQL performance will be very low! To address this constraint, consider the following solutions: Using the raid-0+1 disk array, it is important not to try to use Raid-5,mysql on the RAID-5 disk array as quickly as you might expect.②CPU for MySQL applications,

constraint, consider the following solutions: Using the raid-0+1 disk array, it is important not to try to use Raid-5,mysql on the RAID-5 disk array as quickly as you might expect.②CPU for MySQL applications, it is recommended to use S.M.P. Architecture's multi-symmetric CPU, for example: two Intel Xeon 3.6GHz CPUs can be used, now I would rather recommend 4U servers dedicated to database server, not just for MySQL.③ physical memory for a database se

Background environment:Two servers, configure 4u (per U6 core), 48G memory, install a good system;Problem:SQL Server clusters cannot be installed properly, and the cluster does not support 24-core CPUs.Workaround:After the CPU is changed to 8 cores, it can be successfully installed and then upgraded to the SP3 patch to support 24 cores.Reference:http://903706.blog.51cto.com/893706/406110This article comes from the "Ricky's blog" blog, please be sure t
