Abstract: Methods, systems, and devices for power control for boot-up of memory systems are described. A memory system may be configured to boot-up using two different power modes: a lower-power mode, and a higher-power mode. The memory system may perform a series of evaluations to determine whether the memory system is to switch to the lower-power mode during boot-up operations, or stay in the higher-power mode. For example, the memory system may check one or more of: a history of previous boot-up failures, a voltage of an associated power management integrated circuit, a history of asynchronous power loss at the device, a power-mode configuration of the host device, or a history of host-initiated power-down commands. In some examples, by switching to the lower-power mode, the memory system may avoid repeatedly failing multiple boot-up cycles and may instead successfully boot-up the memory system.

Abstract: In a storage system that implements RAID (D+P) protection groups a drive subset initially has (D+P) drives plus a spare drive with (D+P) splits. Spare splits are distributed with drive index and split index adjacency such that no single drive or split index contains multiple spare splits. When the drive subset is incremented by one drive a group of selected splits are relocated to the new drive based on drive index and split index adjacency such that no single drive or split index contains multiple members of a new protection group. If one of the drives is failing or fails, then an adjusted spare split index value is calculated for each protection group member on that drive so that the protection group members are rebuilt or relocated without placing more than one member of any protection group on a single drive. Adjusted spare split index values may be calculated in steps using the data split indices in ascending order and the largest drive indices in descending order.
