following options:
Performance optimization for SSDs: Improved SAS/SATA controller performance to match
an array of SSDs.
Flash tiering enablement: A data-tiering enabler to support hybrid environments of SSDs
and HDDs, realizing higher levels of performance.
MegaRAID recovery: A data recovery feature that works both in preboot and OS
environments.
