Abstract: A subset of drives with protection groups that have D data members and P parity members is created with (W+1) drives each having W partitions where W=(D+P). A single partition protection group is created in the lowest numbered partition of the W lowest numbered drives. Spares are created at drive X partition Y that satisfy X+Y=W+2. Members of additional protection groups with W members are symmetrically distributed on remaining partitions such that the protection group member at drive X partition index Y belongs to protection group N: if (X+Y)<(W+2), then N=(X+Y?2); and if (X+Y)>(W+2), then N=(X+Y?W?2). The spares are used to rebuild partitions in the event of drive failure. When a new drive is added the first W protection group members in the lowest numbered unrotated partition are rotated onto the new drive. The single partition protection group is excluded from rotation. Partitions vacated by rotated protection group members and a rotated spare are used to create a new protection group.

Abstract: In various embodiments, a technique can be provided to address debug efficiency for failures found on an operational system. The approach can make use of an existing pin on a memory device with added logic to respond to a trigger signal structured different from a signal that is normally sent to the existing pin on the memory device such that the memory device performs a normal or routine function of the memory device in response to the signal. In response to detecting one or more error conditions associated with the memory device, a system that interfaces with the memory device can generate the trigger signal to the memory device. In response to receiving the trigger signal, the memory device can dump an error log of the memory device to a memory component in the memory device. The error log can later be retrieved from the memory component for failure analysis.
