Auto-resume uses non-volatile RAM NVRAM to save the rebuild progress during a host reboot or power failure to automatically resume from the last checkpoint. Consistency check for background data integrity Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent. 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. System availability and application functionality remain unaffected. WebBIOS configuration utility for pre-boot array configuration and management WebBIOS 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.

No, create an account now. Fast initialization quickly writes zeros to the first and last sectors of the virtual drive. 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 m51110 using power from the flash power module.

Auto-resume ensures that data integrity is maintained throughout the process. Server support The following tables list the servers that support the M and Me.

ServeRAID provides the ability to define a physical disk as a hot spare megaraaid replace a failed drive. Mar 13, Messages: Up to 63 drives are supported in a JBOD configuration. The primary feature upgrades, on which the secondary upgrades depend, are listed in their respective columns.

Patrol read for media scanning and repairing Patrol read is a background sentry service designed to pro-actively discover and correct media defects bad sectors that arise normally as a disk drive ages. Some upgrades do not depend on other upgrades and can be applied to “out-of-the-box” controllers we call them primary upgrades.
