Patent abstract
Systems and techniques for varying the spindle speed of a hard disk drive are disclosed. In some embodiments, the systems and techniques involve a hard disk drive (HDD) that is accessible to a storage controller. A spin speed of the HDD is set to a full spinning speed, and an amount of time that the HDD is unassigned is compared to a threshold. After detecting that the threshold is exceeded, the spin speed of the HDD is decreased to a reduced spinning speed. Likewise, upon determining that the HDD is assigned, the spin speed of the HDD is increased to the full spinning speed. In various such embodiments, assigning the HDD may include assigning the HDD to a volume group or assigning the HDD operate as an in-use hot spare.
