The level of consistent low latency it provides should go far beyond disk-based object storage systems.The Flashblade design uses 15 aligned blades in 4U space, and the device is capable of achieving petabytes of storage

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 server using MySQL, the server memory is recommended not less than 2GB, recommended to use more than
