Glusterfs's new tiering feature helps assure that data is available and accessible at the correct performance level thus satisfying both cost and performance concerns. This presentation will explain the Glusterfs's automated tiering feature followed by a live demonstration, and provide performance benchmark results from different hardware configurations. Glusterfs tiering monitors and identifies the activity level of the data and automatically promotes active data to hot SSD based storage and demotes inactive data to cold SATA based storage. Hence, the data movement can happen in either direction, based on the access frequency. The demonstration from Quanta/QCT labs (commodity x86 hardware) will show how to implement a hot tier based on SSD drives (optimized for performance) and attach it to an Erasure coded Glusterfs volume that is based on SATA drives (optimized for cost/capacity).
