Drive roamingDrive roaming occurs when the physical disks are changed to different ports on the same controller.A dedicated hot spare allows the user to assign a hot spare drive to a particular array of the same drive type. A global hot spare allows any physical drive to be designated as a hot spare. Hot spares can be configured as either global or dedicated. ServeRAID can define a physical disk as a hot spare to replace a failed drive. Global and dedicated hot spare with revertible hot spare supportA hot spare rebuilds data from all virtual disks within the disk group in which it is configured. ![]() Patrol read can be activated by a manual command or automatically. 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. The task is interruptible based on controller activity and host operations. 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. Patrol read for media scanning and repairingPatrol read is a background sentry service that pro-actively discovers and corrects media defects (bad sectors) that arise normally as a disk drive ages.Extensive online configuration options and advanced monitoring and event notificationManagement tools provide convenience for the configuration of logical volumes and alerting when errors have occurred or are about to occur.Consistency checks can be scheduled to take place periodically. The consistency check mirrors data when an inconsistent stripe is detected for RAID 1 and re-creates the parity from the peer disks for RAID 5 or RAID 6. Consistency check for background data integrit圜onsistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent.This feature allows you to immediately start writing data to the virtual drive while the initialization is running in the background. Fast initialization for quick array setupFast initialization quickly writes zeros to the first and last sectors of the virtual drive.System availability and application functionality remain unaffected. Online RAID Level MigrationOnline RAID Level Migration, which is also known as logical drive migration, can migrate a virtual disk from any RAID level to any other RAID level without requiring a reboot.Online Capacity ExpansionOnline 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.Applications, such as email and web server, benefit from avoiding downtime during the transition. The card supports a number of features that can be implemented without rebooting the server. Auto-resume ensures that data integrity is maintained throughout the process. Auto-resume on array rebuild or array reconstruction after the loss of system powerAuto-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.The ServeRAID M5210 and M5210e SAS/SATA controllers have the following standard features: ![]()
