Web12 okt. 2016 · That triggers write IOPs to the aggregate in that 4-10ms range as described above. Thus a long as disk is keeping up bandwidth-wise with the total combined write load of the volumes, volume writes can get really good latency performance in the sub millisecond range while the disks are steady at 4-10ms per backend IOP. WebThese scenario tests simulate OLTP and VDI workloads measuring IOPS and latency while additional workloads including decision support system (DSS) are started across other nodes in the cluster. Consistently high IOPS and consistently low latency after the other workloads are introduced indicate better performance. WebIOPS represents how quickly a given storage device or medium can read and write commands in every second. The “back end” IOPS relates to the physical constraints of the media itself, and equals 1000 milliseconds / (Average Seek Time + Average Latency), with the latter two also measured in milliseconds. chilled movie
