Abstract: Systems, methods and/or devices are used to store metadata in a storage system. In one aspect, an indication of data to be stored by the storage system is received by a computing device including non-volatile memory and a tiered data structure. A leaf having a first leaf type is selected from the tiered data structure. Leaves of the first leaf type include locations of variable-length data stored in the non-volatile memory. At least one criterion is used to determine whether to convert the selected leaf to a converted leaf having a second leaf type. Leaves of the second type include locations of fixed-length data. In response to a determination to convert the selected leaf to a converted leaf, first location information is stored in the converted leaf. In response to a determination to not convert the selected leaf, second location information is stored in the second leaf.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for grouping storage ports based on distance. A distance module may be configured to assign distance values to a plurality of ports. Distance values may be for data communications between a node and ports. A group module may be configured to assign one or more ports of a plurality of ports to one of a first port group and a second port group based on assigned distances. A selection module may be configured to select a second port group for data communications between a node and a non-volatile storage medium in response to a first port group being unavailable.

Abstract: A signal projecting device wearable on an athlete about to throw a projectile, such as shooting a basketball. The device incorporates a leveling sensor arranged to provide an input signal to the projecting device so that a signal indicative of a body part on which the projecting device is mounted being horizontal with respect to a floor or ground surface. The projecting device may project a generally cruciform light beam of one characteristic, such as color or light pattern, when the horizontal condition is sensed. A second light beam of a different characteristic may be projected when the horizontal condition is not sensed.
