Considerations during I/O Subsystem Design
Question # 1: 10 Marks
In the following table, different parameters (Elapsed time and CPU time) are given in the context of CPU performance; you need to calculate the I/O time and percentage of elapsed time on each I/O operation.
Percentage of Elapsed Time
Question # 2: 10 Marks
In the following table, different parameters (bus request time, arbitration time and average time to complete an operation) are given in the context of Bus Arbitration; you need to calculate the maximum number of IOPS (Input/Output Operations Per Second) and discuss the possibility of performing 30 million IOPS on each bus.
Note: nsec = nano seconds = 10-9 seconds
Bus Request Time
Average Time to complete an Operation
Maximum No. of IOPS
Is possible to perform 30 million IOPS
