Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent. Consistency checks can be scheduled to take place periodically. Management tools provide convenience for the configuration of logical volumes and alerting when errors have occurred or are about to occur.
Patrol read is a background sentry service that pro-actively discovers and corrects media defects bad sectors that arise normally as a disk drive ages. The service issues a series of verify commands, and if a bad block is discovered, the card's firmware uses RAID algorithms to re-create the missing data and remap the sector to a good sector. The task is interruptible based on controller activity and host operations. The firmware also provides an interface where the patrol read task can be initiated, set up for continuous operation, and terminated from a management application.
Patrol read can be activated by a manual command or automatically. A hot spare rebuilds data from all virtual disks within the disk group in which it is configured. ServeRAID can define a physical disk as a hot spare to replace a failed drive. Hot spares can be configured as either global or dedicated. A global hot spare allows any physical drive to be designated as a hot spare. A dedicated hot spare allows the user to assign a hot spare drive to a particular array of the same drive type.
Drive roaming occurs when the physical disks are changed to different ports on the same controller. When the drives are placed on different channels, the controller detects the RAID configuration from the configuration data on the drives. HII is a utility that is built into the ServeRAID controller that allows you to configure drive groups and logical drives before installing or booting the operating system. It allows you to configure, monitor, and maintain drive groups, virtual drives, and advanced features with an intuitive GUI, reducing administrative efforts and simplifying troubleshooting.
This is a Features on Demand upgrade and one upgrade is needed per server; all M and M series adapters installed in the server will have this upgrade enabled automatically.
MegaRAID SafeStore encryption services offer instant secure erase and local key management for self-encrypting drives. This technology represents a step forward in securing data on a disk drive from any unauthorized access or modification resulting from theft, loss, or repurposing of drives.
Instant secure erase permanently removes data when repurposing or decommissioning SEDs. SafeStore local key management provides the necessary management and protection of SEDs by using a simple pass phrase, security key identifier, and security key file that can be set and applied to all SEDs that are assigned to a ServeRAID adapter.
To avoid the possibility of data loss or corruption during a power or server failure, flash cache protection technology transfers the contents of the DRAM cache to NAND flash using power from the offload power module.
This feature boosts the performance of applications with a highly random data storage access pattern, such as transactional databases. This is a Features on Demand upgrade and only one upgrade is needed per server; all M and M series adapters installed in the server will have this upgrade enabled automatically.
CacheCade software tracks data storage access patterns and identifies the most frequently accessed data. Additional optional functional upgrades are available to expand the standard capabilities. Some upgrades do not depend on other upgrades and can be applied to standard controllers we call them primary upgrades. Certain upgrades cannot be applied to standard controllers and require that other upgrades are enabled before applying these upgrades we call them secondary upgrades.
Hardware upgrades contain physical parts for example, cache module or supercapacitor. FoD upgrades are software licenses. The following table lists the available primary upgrades, their capabilities, and types.
The following table shows the secondary upgrades, their capabilities, types, and dependencies. The primary feature upgrades, on which the secondary upgrades depend, are listed in their respective columns. In the case of the x X6, if you have partitioning enabled, then the FoD upgrade will enabled the feature on all Mseries adapters installed in that partition; the other partition will require a separate FoD upgrade.

Online Capacity Expansion Online Capacity Expansion OCE allows the capacity of a virtual disk to be expanded by adding new physical disks or making use of unused space on existing disks, without requiring a reboot.
Fast initialization for quick array setup Fast initialization quickly writes zeros to the first and last sectors of the virtual drive. Consistency check for background data integrity Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent.
