Systems and methods for sampling a set of block IDs to facilitate estimating an amount of data stored in a data set of a storage system having one or more characteristics are provided. According to an example, metadata (e.g., block headers and block IDs) may be maintained regarding multiple data blocks of the data set. When one or more metrics relating to the data set are desired, an efficiency set, representing a subset of the block IDs of the data set, may be created to facilitate efficient calculation of the metrics by sampling the block IDs of the data set. Finally, the metrics may be estimated based on the efficiency set by analyzing one or more of the metadata (e.g., block headers) and the data contained in the data blocks corresponding to the subset of the block IDs and extrapolating the metrics for the entirety of the data set.

Creation and use of an efficiency set to estimate an amount of data stored in a data set of a storage system having one or more characteristics

A management system is described. The management system includes an interface coupled to a plurality of infrastructure appliances and one or more processors to monitor each of the plurality of infrastructure appliances, detect a malfunction at a first of the infrastructure appliances, and transmit a display message to one or more of the plurality of infrastructure appliances that are adjacent to the first infrastructure appliance, wherein a display message indicates one or more activity light indicators to be activated at an adjacent infrastructure appliance.

Malfunctioning system identification mechanism

A management system is described. The management system includes an interface coupled to a plurality of infrastructure appliances and one or more processors to monitor each of the plurality of infrastructure appliances, detect a malfunction at a first of the infrastructure appliances, and transmit a display message to the first infrastructure appliance including a message to be displayed at one or more activity light indicators at the first infrastructure appliance.

Infrastructure appliance malfunction detection

Systems and methods for sampling a set of block IDs to facilitate estimating an amount of data stored in a data set of a storage system having one or more characteristics are provided. According to an example, metadata (e.g., block headers and block IDs) may be maintained regarding multiple data blocks of the data set. When one or more metrics relating to the data set are desired, an efficiency set, representing a subset of the block IDs of the data set, may be created to facilitate efficient calculation of the metrics by statistically sampling the block IDs of the data set. Finally, the metrics may be estimated based on the efficiency set by analyzing one or more of the metadata (e.g., block headers) and the data contained in the data blocks corresponding to the subset of the block IDs and extrapolating the metrics for the entirety of the data set.

Disclosed are systems, computer-readable mediums, and methods for transforming data in a file system. As part of a recycling process, a determination is made that transformations should be attempted. A data block is determined to be in use by at least one user of the storage system. If a transformation should be attempted on the data block is determined. Parameters associated with the performance of the file system can be used in this determination. A type of transformation to be done is determined. The data block is transformed based upon the selected transformation. The transformed data block is written to the storage system. As part of the recycling process, the transformation requires no additional input/output requests.

Data transformation during recycling

A golf putting practice apparatus comprising a rectangular frame defining a putting area. A rebound member is located at one end of the putting area, and a locating cord with three locating beads moveably mounted thereon extends between the ends of the frame. A putting stroke is established by setting the locating beads at designated locations to define the limits of the backstroke and follow through, as well as the position of the ball. Alignment locating clips are provided.

Golf putting improvement and teaching apparatus and method

A golf exerciser comprising a handle to be manually grasped, a stretchable cord assembly attached to one end of the handle, with the other end of the cord assembly attached to a doorknob. The person assumes a golfing stance and grasps the handle in the lead hand (which for a right handed golfer would normally be the left side), and pulls the handle away from the doorknob, thus strengthening the muscle in the left hand. The cord assembly desireably comprises one cord of a shorter unstretched length, and a second cord of a greater unstretched length, so that there is a lead-in exercise motion with lesser resistance, followed by a power mode where a handle is pulled and rotated by the wrist to give isometric exercise.
