The following results were achieved during measurements with 12 tasks on 6 volumes, using FastDPAV with 6 base davices and 6 alias devices. Hence. for each task one free base or alias devices was available. First measurements were conducted using only 1 channel path. For the second measurement run with the same load another channel path was added.
Channels | Vol. | Tasks | seq. read | seq. write | random25 | |||
IO/s | Mbyte/s | IO/s | Mbyte/s | IO/s | Mbyte/s | |||
1 | 6 | 12 | 27,603 | 1,015 | 27,060 | 1,299 | 27,230 | 1,200 |
2 | 6 | 12 | 43,923 | 2,012 | 38,070 | 2,037 | 42,262 | 2,085 |
With 2 channel paths, the throughput and IO rates are significantly higher than with only one. They aren't doubled, as also the IO system of the SU710 and the storage system limit the performance.
However, depending upon the particular appication scenario, IO performance can be increased by connecting further channels.
