MySQL with SSD/HDD
Posted by: Tobias K. ()

Hello,

since our InnoDB database size (75GB) exceeds the RAM size (32GB), we plan to use SSD drives to speed up our MySQL Server.
Hardware specs:
- 32GB ECC RAM
- 2x 1 TB RAID 1
- RAID Controller: LSI Logic / Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05)

MySQL settings:
innodb_flush_method = O_DIRECT
innodb_buffer_pool_size = 26624M
innodb_log_file_size = 256M
innodb_log_buffer_size = 8M

We want to use the free RAID ports to install two 240 GB 6 Gb/s SSD (RAID 1).

After reading some articles about MySQL SSD/HDD performance, I would use the SDD for all innoDB data except for Redo log and ibdata, which I would put on HDD.
Is this a good setup? Is it better to leave the OS (Ubuntu Linux) on HDD, or will performance be better if the OS is installed on SSD?

Thanks!
