Abstract: One or more techniques and/or systems are provided for managing configuration updates used to replicate configuration of a primary storage virtual machine to a partner storage virtual machine. For example, the partner storage virtual machine may be configured to provide failover operation in place of the primary storage virtual machine in the event the primary storage virtual machine fails. Configuration updates are queued and replayed on the partner storage virtual machine to replicate objects of the primary storage virtual machine to the partner storage virtual machine (e.g., replay of create, modify, or delete object commands for synchronizing volumes, logical unit numbers, and/or other configuration objects of the primary storage virtual machine to the partner storage virtual machine). Configuration updates may be retained, modified, or discarded/removed based upon consolidation rules, which improves computing resource utilization by consolidating configuration updates and/or removing stale configuration updates while achieving a similar replication consistency result.

Abstract translation: 提供一个或多个技术和/或系统用于管理用于将主存储虚拟机的配置复制到伙伴存储虚拟机的配置更新。 例如，伙伴存储虚拟机可能被配置为在主存储虚拟机发生故障的情况下提供故障切换操作来代替主存储虚拟机。 配置更新在伙伴存储虚拟机上排队和重播，以将主存储虚拟机的对象复制到伙伴存储虚拟机（例如，重播创建，修改或删除对象命令，用于同步卷，逻辑单元号和/ 或主存储虚拟机的其他配置对象到合作伙伴存储虚拟机）。 可以基于合并规则保留，修改或丢弃/删除配置更新，这通过整合配置更新和/或删除过时的配置更新来提高计算资源利用率，同时实现类似的复制一致性结果。

Abstract: One or more techniques and/or systems are provided for clone volume merging. For example, a parent volume may be exposed to users for read and write access to data stored within the parent volume. The parent volume may be cloned to create a cloned volume of the parent volume. The cloned volume may be exposed to users for data access. Responsive to receiving a clone volume merge command, data blocks within the cloned volume may be compared with data blocks within the parent volume to identify delta data blocks within the cloned volume that are not within the parent volume. The delta data blocks may be copied from the cloned volume to the parent volume, which may increase performance and/or decrease time taken to generate a volume with both common data blocks and the delta data blocks, as compared to copying data from the parent volume to the cloned volume.
