    Abstract: Exemplary embodiments for increased in-line deduplication efficiency in a computing environment are provided. Embodiments include incrementing the size of data samples from fixed size data chunks for each nth iteration for reaching a full size of an object requested for in-line deduplication, calculating in nth iterations hash values on data samples from fixed size data chunks extracted from the object, and matching in a nth hash index table the calculated nth iteration hash values for the data samples from the fixed size data chunks with a corresponding hash value of existing objects in storage, wherein the nth hash index table is built for each nth iteration of the data samples belonging to the fixed data chunks.

    Abstract translation: 提供了用于在计算环境中提高在线重复数据删除效率的示例性实施例。 实施例包括从每固定大小的数据块中增加数据样本的大小，以达到用于进行在线重复数据消除所请求的对象的全部大小的第n次迭代的全尺寸的数据样本的大小;在从对象中提取的固定大小数据块的数据样本上进行第n次迭代计算散列值 ，并且在第n个散列索引表中匹配来自具有存储中的现有对象的相应哈希值的固定大小数据块的数据样本的计算的第n个迭代散列值，其中第n个散列索引表是针对 属于固定数据块的数据样本。

    Abstract: Methods, systems, and computer program products are provided for optimizing selection of files for eviction from a first storage pool to free up a predetermined amount of space in the first storage pool. A method includes analyzing an effective space occupied by each file of a plurality of files in the first storage pool, identifying, from the plurality of files, one or more data blocks making up a file to free up the predetermined amount of space based on the analysis of the effective space of each file of the plurality of files, selecting one or more of the plurality of files as one or more candidate files for eviction, based on the identified one or more data blocks, and evicting the one or more candidate files for eviction from the first storage pool to a second storage pool.

    Abstract translation: 提供了方法，系统和计算机程序产品，用于优化从第一存储池中排出的文件的选择以释放第一存储池中的预定量的空间。 一种方法包括分析第一存储池中的多个文件的每个文件所占用的有效空间，从多个文件中识别构成文件的一个或多个数据块，以便基于该文件释放预定量的空间 分析所述多个文件中的每个文件的有效空间，基于所识别的一个或多个数据块，将所述多个文件中的一个或多个作为一个或多个候选文件进行选择，并且驱逐所述一个或多个候选文件 从第一个存储池逐出到第二个存储池。

    Abstract: Embodiments for medical condition communication management by one or more processors. A maturity score and medical condition acceptance score relating to a medical condition of a user may be estimated according to data collected from one or more devices associated with the user. The maturity score may represent a measure of an emotional state, age, and cognitive reasoning ability. The medical condition acceptance score may represent a measure of understanding and acceptance capability of the medical condition. One or more search results responsive to a search query related to the medical condition submitted by the user may be adjusted according to the maturity score, the medical condition acceptance score, and an appropriateness of communications for the one or more search results based on a plurality of identified contextual factors.

    Abstract: Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and in response to the secure deletion of the file not being complete during the disconnection event, indicating on a table a remote inode number assigned to the copy associated with the file at the home site, a name under which the copy is saved, and a list of data chunk tuples specifying selected data of the copy to undergo secure deletion.
