What are the two biggest factors that determine IOPS when using SSDs in a Dell EMC SC Series array?
The reason there is such a large range in the number of IOPS delivered by SSDs is the IOPS are truly dependent on the type of traffic the SC Series was designed to handle. The two biggest factors that will determine IOPS in an SSD environment are block size of the application and overall throughput.
