Calculating the storage throughput
The data transfer rate, or throughput, is the rate at which data can be read from or written to the storage device, and is typically measured in MB/s. Storage adapters, connectivity, and array controllers will need to support the storage throughput requirements.
How to do it...
Throughput should be calculated in order to ensure that the storage controllers and disk can support the required data transfer rates. Throughput is also used to correctly size the storage connectivity bandwidth.
To calculate the storage throughput requirements, perform the following steps:
Determine the IO size of the workload.
Determine the number of IOPS required to support the workload.
Calculate the throughput required.
How it works...
Throughput is calculated by multiplying the IO size of the workload by the number of IOPS. Transactional databases and application servers typically have an IO size between 4k and 64k, whereas file archiving applications, backup applications, and media...
