    • There is provided a multi-shaft kneading disc, kneading disc block, and a multi-shaft extruder containing the same. The kneading disc and each kneading disc in the kneading disc block having a disc shape with a central section defining an extruder shaft mounting bore and at least one lobe extending radially from said central section and having a crest end. The at least one lobe has a radius X which defines an outer diameter of the kneading disc. The central section has a radius Y which defines an inner diameter of the kneading disc. At least one other lobe extends radially from the central section and has a radius Z. The radius Z defines the outer diameter of at least one other lobe. The radius Z of the other lobe is equal to Y+⅞(X−Y) to Y+¼(X−Y).

    • A system, method, and computer-readable medium that facilitate optimized data storage and migration are provided. Storage device zones are tested and assigned respective speed quality ratings. The frequency with which data is accessed within the system may be periodically monitored and a corresponding access frequency quantifier assigned to the data is updated accordingly. The data access frequency quantifier may be associated with a storage device zone speed quality rating. The association between data access frequency quantifiers and the storage device zone speed quality ratings may be made in a hierarchical association such that quantifiable differentials may be ascertained between a particular access frequency quantifier and a storage device zone speed quality rating. In this manner, when no storage zone having a speed quality rating that is associated with data having a particular access frequency quantifier is available for storage of the data, a storage zone having a speed quality rating more proximate the speed quality rating associated with the access frequency quantifier may be identified for migration of the data for storage thereby.
    • 提供了一种促进优化的数据存储和迁移的系统,方法和计算机可读介质。 测试存储设备区域并分配相应的速度质量等级。 可以周期性地监视在系统内访问数据的频率,并且相应地更新分配给数据的对应的访问频率量化器。 数据访问频率量化器可以与存储设备区域速度质量等级相关联。 数据访问频率量化器与存储设备区域速度质量等级之间的关联可以以分级关联进行,使得可以在特定接入频率量化器和存储设备区域速度质量等级之间确定可量化的差分。 以这种方式,当没有具有与具有特定接入频率量化器的数据相关联的速度质量等级的存储区域可用于存储数据时,具有更接近于与访问相关联的速度质量等级的速度品质等级的存储区域 可以识别频率量化器用于数据的迁移,以便存储。
