Live Optics | Optical Prime | Disk Throughput
Summary: This article discusses Disk Throughput.
Instructions
Disk throughput is used to measure the used bandwidth between the host and its storage devices. Throughput is the measurement of bandwidth consumption of a storage device or subsystem from its host or hosts.
This means an aggregated quantity of read in write data transfers reported in x Bytes/per second in an Optical Prime project
Optical Prime measures throughput in terms of the total bandwidth consumed for reading and writing at a host level. There are other factors to consider in when measuring throughput; however Optical Prime distills this measurement. It leaves little guesswork in understanding what the Host OS must fulfill frontend bandwidth requirements are. For storage design to consider how disk devices, arrays, and SANs can handle the throughput needs of the host. Latency must be kept to a minimum.
General guideline
Avg. Throughput = IOPS * Block size
