HP SmartCache, the disk subsystem was able to process approximately four times as many requests than without HP
SmartCache.
Figure 6. Transaction volume through database volume.
Looking at the data another way, we see the
differences in the number of input/output
transactions performed per second (IOPS) with
and without HP SmartCache (Figure 7). Without
HP SmartCache, the disk subsystem was able to
process approximately 5000 requests per second
combining both read and write traffic. With HP
SmartCache, the disk subsystem was able to
process approximately 22,000 requests per
second of both reads and writes. This shows that
the disk subsystem with HP SmartCache is able to
process four times as much data than the system
without HP SmartCache.
