»Filesystem Statistics - Selena Deckelmann & Gabrielle Roth
Biography
Selena Deckelmann works for End Point Corporation from her home in Portland, OR, where she is a database management systems consultant. She is the User Group liaison for the PostgreSQL Global Development Group. She currently leads PDXPUG, a PostgreSQL Users Group, and has helped start a programming group, Code-n-Splode, whose goal is to get more women involved in open source. In her spare time, she collects eggs from her chickens, gardens and occasionally mixes drinks for her local Perl Mongers group.
Gabrielle Roth is a Network Engineer, but is still a biology geek at heart. She lives in Portland, OR with a small but ambitious Monstera deliciosa, Mia. After OSCON 2007, she started Code-n-Splode as an effort to get more women involved in open source projects. When she's not tinkering with networks or databases, she enjoys crashing her mountain bike & practicing parade formations with the PostgreSQL Army of Smurfs. She has been recently engaged in performance benchmarking in the Portland hosted PostgreSQL performance lab.
Abstract
The Linux operating system provides a number of file systems that can be used, as well as volume management and hardware or software RAID. We are running performance benchmarks for database tuning, and are curious if the file systems really behave like we expect them to, especially when used in conjunction with RAID or volume management. Are these file systems being used in manners for which they were designed? There is also more to file systems than how fast we can read to them or how fast we can write to them. How reliable is the file system, and how do be prove it? We have collected data and will have a server available for development during the conference.
