    Abstract: Techniques to managing non-disruptive SAN availability in a partitioned cluster comprising one or more components configured to determine whether to separate a cluster into two or more partitions, notify one or more responsive cluster nodes to separate the cluster into a first partition and a second partition, update one or more access states, notify the host that access states of one or more network paths has been updated, and provide the one or more access states. Other embodiments are described and claimed.

    Abstract: Method and system for detecting migration of a virtual machine are provided. The method detects that a first identifier for identifying a virtual machine and a second identifier identifying a source computing system hosting the virtual machine that accesses a storage space via a logical object have changed, when the virtual machine is migrated from the source computing system to a destination computing system. Thereafter, a storage device at the destination computing system is initialized to operate as a caching device for the migrated virtual machine.

    Abstract translation: 提供了一种用于检测虚拟机迁移的方法和系统。 该方法检测到当虚拟机从源计算系统迁移到一个虚拟机时，用于识别虚拟机的第一标识符和标识识别经由逻辑对象访问存储空间的虚拟机的源计算系统的第二标识符已经改变 目的地计算系统。 此后，将目的地计算系统的存储设备初始化为用于迁移的虚拟机的缓存设备。

    Abstract: Methods and systems for a copy-offload operation are provided. A soft range lock is placed for a data container for generating a token for a copy-offload operation for copying the data container from a source location to a destination location, where presence of the soft range lock indicates that content of the data container has not changed during the copy-offload operation. A token for the copy-offload operation represents the content of data container and includes information regarding the soft range lock. The token with the soft range lock information is provided to the client that requests the copy-offload operation. If the soft range lock exists, then the data container is copied without using a point in time copy of the data container.

    Abstract translation: 提供了用于拷贝卸载操作的方法和系统。 为数据容器放置软范围锁，用于生成用于将数据容器从源位置复制到目标位置的拷贝卸载操作的令牌，其中软范围锁的存在指示数据容器的内容没有 在复制卸载操作期间更改。 用于拷贝卸载操作的令牌表示数据容器的内容，并包括有关软范围锁定的信息。 带有软范围锁定信息的令牌被提供给请求复制卸载操作的客户端。 如果存在软范围锁定，则不使用数据容器的时间点复制数据容器。
