Performance of one task

The tables below show the performance which one user task can achieve without a competitive load in the case of disk accesses to the ETERNUS DX600 S3 storage system:

• I/O rate in the number of IOs per second (IOs/s)

• Throughput in Mbyte/s

The performance was measured for the standardized load types with different block sizes and a read hit rate of 100%: The Mbyte figures are rounded to 1 Mbyte/s.
