    Abstract: A method for increasing virtual storage capacity in on-demand storage systems utilizes data compression to selectively compress data stored in a storage resource to reduce the utilization of physical storage space whenever such physical resources have been over committed and the demand for physical storage exceeds its availability. In one exemplary embodiment, the utilization of the capacity of a shared storage resource is monitored and data is selected for compression based on the utilization. The compression of the selected data is triggered in response to the monitoring results. In addition, policies and rules are defined that determine which data is selected for compression. For example, the selection of data may be based on one or more of the following: a degree of utilization of said capacity of said shared storage resource, a volume size of said data, an indicator of compressibility of said data, a frequency of use of said data, a manual selection of said data, and a predefined priority of said data. The disclosed methods improve the operation of virtual allocation by further enhancing the availability of physical space through data compression. Virtual allocation and block-based data compression techniques are utilized to improve storage efficiency with a minimal risk to system availability and reliability and with a minimal impact to access time and latency.

    Abstract translation: 一种用于增加按需存储系统中的虚拟存储容量的方法利用数据压缩来选择性地压缩存储在存储资源中的数据，以便每当这样的物理资源被过度提交并且对物理存储的需求超过其可用性时减少物理存储空间的利用 。 在一个示例性实施例中，监视共享存储资源的容量利用率并基于利用率选择数据进行压缩。 响应监测结果触发选定数据的压缩。 另外，定义了确定选择哪些数据进行压缩的策略和规则。 例如，数据的选择可以基于以下中的一个或多个：所述共享存储资源的所述容量的利用程度，所述数据的卷大小，所述数据的可压缩性的指示符，使用频率 所述数据的手动选择，以及所述数据的预定优先级。 所公开的方法通过数据压缩进一步增强物理空间的可用性来改善虚拟分配的操作。 利用虚拟分配和基于块的数据压缩技术来提高存储效率，同时将系统可用性和可靠性风险降至最低，并且对访问时间和延迟的影响最小。

    Abstract: A method for extending the service life of a portable device includes monitoring a battery of a portable device; identifying a problem bank; reconfiguring a connection schema for the battery to replace the problem battery bank with at least one spare bank; conditioning or exercising the problem bank; connecting the portable device to a power supply to recharge the problem bank; and reconnecting the recharged or repaired bank according to the connection schema without the at least one spare bank.
