Auto-rebuild
A virtual disk rebuild will begin on system boot automatically if the native virtual disk is degraded and a valid rebuild target is present. A valid
rebuild target is any functional drive attached to the BOSS-S1 device which is not part of the native virtual disk and is of equal or greater
storage capacity. An auto-rebuild occurs without prompting the user, and any data on the rebuild target is overwritten.
Non-RAID disks support
By default, all disks are in an unconfigured state.
NOTE:
•
For BOSS-S1, unconfigured drives are automatically non-RAID drives. To convert RAID drives to non-RAID drives, delete the virtual
disk.
•
BOSS only supports one configured (RAID) and two unconfigured states. BOSS does not break
unconfigured
drives into RAID
and non-RAID states.
TRIM (Non-RAID physical disk)
TRIM allows an operating system to delete a block of data that is no longer considered in use from SSDs. For supported operating systems,
the TRIM command resolves the Write Amplification issue. When an operating system deletes a file, the file is marked for deletion in the file
system, but the contents on the disk are not actually erased. As a result, the SSDs do not know the LBA (Logical Block Addressing)
previously occupied can be erased. With the introduction of TRIM, when a file is deleted, the operating system sends a TRIM command
along with the LBAs that do not contain valid data to the physical disk.
Quick initialization
Quick initialization is a feature that enables you erase the files and file systems from the virtual disk while keeping the virtual disk
configuration intact.
Erase physical disk
Erase physical disk feature deletes metadata from the physical disk. This feature can be enabled only when the physical disk is not part of
any virtual disk.
