Abstract
Physical storage devices are configured as a redundant array of independent disks (RAID). As such, storage space of the physical storage devices is allocated to the RAID, and each physical storage device is part of the RAID. Where a portion of the storage space of the physical storage devices is not allocated to the RAID, this portion of the storage space from a mixed drive capacity is configured so that it is usable and is not wasted.
Claims18
A method comprising:
- configuring, by a device, a plurality of physical storage devices as a redundant array of independent disks (RAID), such that storage space of the physical storage devices is allocated to the RAID, and such that each physical storage device is part of the RAID;
- and,
- where a portion of the storage space of the physical storage devices is not allocated to the RAID, configuring the portion of the storage space, by the device, so that the portion of the storage space is usable and is not wasted.
A system comprising:
- a plurality of physical storage devices configurable as a redundant array of independent disks (RAID), such that upon configuration of the physical storage devices as the RAID, storage space of the physical storage devices is allocated to the RAID and each physical storage device is part of the RAID;
- and,
- a controller to, where upon configuration of the physical storage devices as the RAID a portion of the storage space of the physical storage devices is not allocated to the RAID, configure the portion of the storage space so that the portion of the storage space is usable and is not wasted.
A hardware controller for a plurality of physical storage devices configurable as a redundant array of independent disks (RAID) such that upon configuration of the physical storage devices as the RAID, storage space of the physical storage devices is allocated to the RAID and each physical storage device is part of the RAID, the hardware controller comprising:
- a unit implemented in hardware to, where upon configuration of the physical storage devices as the RAID a portion of the storage space of the physical storage devices is not allocated to the RAID, configure the portion of the storage space so that the portion of the storage space is usable and not wasted.
A computer program product comprising:
- a computer-readable storage medium having computer-readable code embodied therein, the computer-readable code executable by a processor in relation to a plurality of physical storage devices configurable as a redundant array of independent disks (RAID) such that upon configuration of the physical storage devices as the RAID, storage space of the physical storage devices is allocated to the RAID and each physical storage device is part of the RAID,
- wherein the computer-readable code is to where upon configuration of the physical storage devices as the RAID a portion of the storage space of the physical storage devices is not allocated to the RAID, configure the portion of the storage space so that the portion of the storage space is usable and not wasted.
