ServeRAID M5000 Series Performance Accelerator Key for IBM System x 7
RAID 0 random workload performance
With MegaRAID FastPath enabled, SSD configurations tuned for small, random block-size IO activity —
typical of transactional database applications — can sustain over 150,000 I/O reads per second in RAID 0
configurations. This is two times the transactional performance of identical configurations when the
MegaRAID FastPath software is disabled. This is particularly evident in 4 K random reads and random
writes, as well as 4 K and 8 K OLTP transaction-oriented benchmarks.
In Figure 5, note that in the standard mode where MegaRAID FastPath software is not enabled, arrays
are able to reach more than 80,000 IOPs. This is due to additional performance tuning optimizations over
previous 6 Gbps MegaRAID SATA+SAS generations. However, with the MegaRAID FastPath software
enabled, users can experience more than a 70% increase in IOPs throughput.
