How do you choose the right filesystem for your database management system?
Administrators have a variety of filesystems to choose from, as well as volume management and hardware or software RAID. This talk will examine how different the performance of filesystems really are, and how do you go about systematically determining which configuration will be the best for your application and hardware.
This talk will present data generated by a group of volunteers running performance tests for database tuning. We were curious if the file systems would really behave like we expected them to, especially when used in conjunction with RAID or volume management.
There is also more to file systems than how fast we can read to or write to them. Reliability is critical for production environments, and proving that is a key part of evaluating performance.
The talk will review and confirm or deny assumptions that many system administrators and developers make about filesystems and databases.
Data shared will include baseline throughput determined with exhaustive fio tests.
