Single System Image is a desirable property for all services provided by a cluster environment. Coherently with this principle, cluster file systems should make data distribution transparent to the application, giving rise to a heavy communication workload induced by I/O activity. Hence, I/O performance greatly depends on communication performance and on how the storage and network subsystems interact at all levels. The authors present a detailed performance analysis of the storage and network subsystems of a properly configured cluster node. In particular, we consider the case of an Ultra2 SCSI controller with multiple attached disks sharing the I/O bus with a Gigabit LAN adapter. The analysis helps to understand how the several hardware and software components interact, which are the potential bottlenecks, and how these bottlenecks affect the overall performance.

Abstract
Single System Image is a desirable property for all services provided by a cluster environment. Coherently with this principle, cluster file systems should make data distribution transparent to the application, giving rise to a heavy communication workload induced by I/O activity. Hence, I/O performance greatly depends on communication performance and on how the storage and network subsystems interact at all levels. The authors present a detailed performance analysis of the storage and network subsystems of a properly configured cluster node. In particular, we consider the case of an Ultra2 SCSI controller with multiple attached disks sharing the I/O bus with a Gigabit LAN adapter. The analysis helps to understand how the several hardware and software components interact, which are the potential bottlenecks, and how these bottlenecks affect the overall performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
