Abstract: A beverage crate include a base, a pair of opposed side walls extending upward from the sides of the base and a pair of end walls extending upward from ends of the base. The end walls each include a pair of spaced apart end columns. A handle extends across the pair of spaced apart columns at each end wall. The height of the handle is aligned with a portion of the bottle having a reduced diameter. For example, some bottles have a tapered or contoured middle portion to facilitate grasping the bottle. This allows the handle to be positioned closer to the bottles, which reduces the overall length of the crate. The reduced length of the crate then permits a reduced width of the crate per the required ratio for cross-stacking. The reduced width then permits a full bottle capture on the bottom surface of the crate.

Abstract: Allocation process that allows erasure coded data to be stored on any of a plurality of disk drives, in a pool of drives, so that the allocation is not tied to a fixed group of drives. Still further, the encoded data can be generated by any of multiple different erasure coding algorithms, where again storage of the encoded data is not restricted to a single group of drives based on the erasure algorithm being utilized to encode the data. In another embodiment, the encoded data can be "stacked" (aligned) on select drives to reduce the number of head seeks required to access the data. As a result of these improvements, the system can dynamically determine which one of multiple erasure coding algorithms to utilize for a given incoming data block, without being tied to one particular algorithm and one particular group of storage devices as in the prior art.
