摘要： A method, system and program product for enabling migration of Virtual Machines with concurrent access to data across two geographically disperse sites to enable load balancing across the two geographically disperse sites, by presenting over a network a read writable logical volume at a first site, presenting over a network a read writable logical volume at a second geographically disparate site; wherein the first volume and the second volume are configured to contain the same information, and enabling read write access to the volume at the first site or the volume at the second site for a first virtual machine while keeping the data consistent between the two sites to enable transparent migration of the virtual machine to load balancing across the two sites according to at least one load balancing metric.
摘要翻译：一种方法，系统和程序产品，用于通过在两个地理上分散的站点之间并行访问数据来实现虚拟机的迁移，以通过在网络上呈现第一站点上的可读写逻辑卷来呈现跨两个地理分散站点的负载平衡，呈现通过网络在第二地理上不同的站点上的可读写逻辑卷; 其中所述第一卷和所述第二卷被配置为包含相同的信息，并且对于第一虚拟机启用对所述第一站点处的卷的读取写入访问或第二站点处的卷的读写访问，同时保持所述两个站点之间的数据一致启用虚拟机的透明迁移，以便根据至少一个负载均衡度量来跨两个站点进行负载平衡。

摘要： A reclaim system frees previously allocated, but currently unused, storage space in a thin or virtual provisioning environment. The reclaim system may be used in connection with a maintenance operation performed upon determining that significant allocated space of a thin device is no longer being used or may be performed periodically to analyze a thin device and free appropriate space back to a thin device storage pool. In an embodiment, the reclaim system may run online while user applications are accessing a target storage volume.
摘要翻译：回收系统可以在瘦或虚拟配置环境中释放以前分配的但是当前未使用的存储空间。回收系统可以在确定薄设备的重要分配空间不再被使用或周期性地执行以分析薄设备并将适当的空间释放回薄设备存储池时执行的维护操作结合使用。在一个实施例中，回收系统可以在用户应用程序访问目标存储卷时在线运行。

摘要： Methods and systems are disclosed that relate to identifying an appropriate logical unit for a requested application storage allocation. An exemplary method includes receiving a request for storage allocation comprising a plurality of storage attributes including capacity and at least one performance and/or availability criterion. The method further includes identifying a logical unit having at least one designated storage characteristic that satisfies the at least one criterion and having an available storage space that satisfies the capacity and allocating at least a portion of the identified logical unit for storage associated with the request.
摘要翻译：公开了涉及为所请求的应用程序存储分配识别适当的逻辑单元的方法和系统。一种示例性方法包括接收包括包括容量和至少一个性能和/或可用性标准的多个存储属性的存储分配请求。所述方法还包括识别具有满足所述至少一个准则的至少一个指定存储特性的逻辑单元，并且具有满足所述容量的可用存储空间并且分配用于与所述请求相关联的存储的至少一部分所识别的逻辑单元。
