“…Besides the different functionalities that they offer, they handle some patterns much better than others due to their internal design. Both of these aspect of a heterogeneous cluster configuration have been shown in our previous paper [14].…”

“…In our previous paper [14] we looked at the option of offering distinct storage pools using different file systems. In this paper we extend this work and look at the impact of changing a single parameter in the Ceph configuration on the performance when tested through an OpenStack cloud deployment using block storage devices.…”

“…En este caso, la extensión de jumbo frames no está habilitada para las pruebas de esta tesis. El trabajo de Meyer y Morrison Impact of single parameter changes on Ceph Cloud storage performance (Meyer, 2016) concluye que el impacto de los jumbo frames en un cluster grande es poco significativo porque la carga de la replicación se distribuye y la dependencia del ancho de banda es menor; pero cuando el cluster es chico, el ancho de banda entre los nodos es un factor limitante.…”

“…Vamos ahora a testear la performance de la capa RADOS y LIBRADOS. En su trabajo "Supporting Heterogeneous Pools in a Single Ceph Storage Cluster", (Meyer, 2016) los autores plantean que las aplicaciones tienen diferentes cargas de trabajo y patrones de acceso sobre el almacenamiento, y que normalmente el filesystem distribuido provee a esa variedad de aplicaciones una solución bastante homogénea y diseñada para un escenario "genérico", lo que afecta la performance en varios casos. Así, dependiendo de la aplicación, la métrica que tendría mayor importancia puede ser el throughput mientras que en otras podría ser la latencia promedio, o la latencia máxima, o una mezcla de todas.…”
