Tekmart Africa caveat:

Some ServeRAID M5016, M5110, and M5115 SAS/SATA controllers are susceptible to online resets, early in their life, during heavy Input/Output (I/O). The frequency of online resets varies directly with I/O throughput. This issue has been observed to occur simultaneously with a virtual disk consistency check, and a hard disk drive (HDD) Patrol Read.

A momentary loss of performance for a few seconds could be observed while the controller resets itself.

The firmware level does not contribute to the online resets. This is a recoverable event, and has no impact on data.

Data will be stored in the controller's flash-based memory, and then off-loaded after the reset completes. You can identify if online resets occurred by observing the following MegaRAID Storage Manager (MSM) event: Controller encountered a fatal error and reset
