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. ServeRAID can define a physical disk as a hot spare to replace a failed drive. See ServerProven for the latest information about the System x servers and drives support: The task is interruptible based on controller activity and host operations. Support for servers with Intel Xeon v3 processors Table 5. Global and dedicated hot spare with revertible hot spare support A hot spare rebuilds data from all virtual disks within the disk group in which it is configured.

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.

Up to 12 Gbps throughput per port. Support for servers with Intel Xeon v2 processors Table 6. See ServerProven for the latest information about the System x servers and drives support: The following terms are trademarks of Lenovo in the United States, other countries, or both: Introduction Did you m520
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. HII is a utility that is built into the ServeRAID controller that j5200 you to configure drive groups and logical drives before installing or booting the operating system.
Extensive online configuration options and advanced monitoring and event notification Management tools provide convenience for the configuration of logical volumes and alerting k5200 errors have occurred or are about to occur. FoD upgrades are software licenses. A dedicated hot spare allows the user to assign a hot spare drive to a particular array of the same drive type. 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.
Consistency checks can be scheduled to take place periodically. Part number information Features M52000 specifications Feature upgrade matrix Server support. There are two types of available upgrades: Support for up to 64 virtual disks, up to arrays, up to 16 virtual disks per array, and up to 32 physical drives per array.
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.

Auto-resume ensures that data integrity is maintained throughout the process. Fast initialization for quick array setup Fast initialization quickly writes zeros to the first and last sectors of the virtual drive.

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 m5200. A hot spare rebuilds data from all virtual disks within the disk group in which it is configured. Authors Ilya Krutov David Watts. The following table shows the secondary upgrades, their capabilities, types, and dependencies. In the case of the x X6, if you have partitioning enabled, then the FoD upgrade m52000 enabled the feature on all Mseries adapters installed in that partition; the other partition will require a separate FoD upgrade.
Primary feature upgrades Secondary feature upgrades. They are implemented through Features-on-Demand FoD software licenses. The primary feature upgrades, on which the secondary upgrades depend, are listed in their respective columns. This feature boosts the performance of applications with a highly random data storage access pattern, such as transactional databases. This feature allows you to immediately start writing data to the virtual drive while the initialization is running in the background.
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. The card supports a number of features that can be implemented without rebooting the server.
MegaRAID SafeStore encryption services offer instant secure erase and local key management for self-encrypting drives. Drive roaming Drive roaming occurs when the physical disks are changed to different ports on the same controller. The task is interruptible based on controller activity and host operations.
Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent.
