Abstract
The Florida CMS Tier2 center, one of the CMS Tier2 centers, has been using the Lustre filesystem for its data storage backend system since 2004. Recently, the data access pattern at our site has changed greatly due to various new access methods that include file transfers through the GridFTP servers, read access from the worker nodes, and the remote read access through the xrootd servers. In order to optimize the file access performance, we have to consider all the possible access patterns and each pattern needs to be studied separately. In this presentation, we report on our work to optimize file access with the Lustre filesystem at the Florida CMS T2 using an approach based on analyzing these access patterns.

The Florida CMS[1] Tier2 center is one of the CMS T2 centers in the USA
We report on our work to optimize file access with the Lustre filesystem at the Florida CMS T2 using an approach based on analyzing these access patterns
The methodology is not limited to Lustre but can be applied to other storage systems
