Abstract: A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses a storage array, yet lacks command channels to the storage array. The forwarder media agent forwards commands directed at the storage array to the snap-MA, which receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent. The snap-MA pools storage-array-command devices to avoid capacity limitations in regard to communications channels at the storage array. The snap-MA operating in conjunction with the forwarder media agents enable the illustrative system to consolidate the communication of storage-array commands away from client computing devices and/or proxy media agent hosts and into the secondary storage computing device that hosts the snap-MA.

Abstract: The illustrative systems and methods consolidate storage-array command channels into a media agent that executes outside the production environment. A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses the storage array, yet lacks command channels to the storage array. Likewise, a “forwarder” proxy media agent may operate without command channels to the storage array. No third-party libraries or storage-array-command devices are installed or needed on the host computing device. The forwarder media agent forwards any commands directed at the storage array to the snap-MA on the secondary storage computing device. The snap-MA receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent. The snap-MA advantageously pools any number of storage-array-command devices so that capacity limitations in regard to communications channels at the storage array may be avoided. As a result, the snap-MA operating in conjunction with the forwarder media agents enable the illustrative system to consolidate the communication of storage-array commands away from client computing devices and/or proxy media agent hosts and into the secondary storage computing device that hosts the snap-MA.

Abstract translation: 说明性的系统和方法将存储阵列命令通道整合到在生产环境之外执行的媒体代理。 在与客户端计算设备分离的辅助存储计算设备上配置“快照控制媒体代理”（“snap-MA”）。 “转发器”媒体代理对使用存储阵列的每个客户端计算设备进行操作，但缺少对存储阵列的命令通道。 类似地，“转发器”代理媒体代理可以在没有命令通道的情况下操作存储阵列。 在主机计算设备上没有安装或需要第三方库或存储阵列命令设备。 转发器媒体代理将指向存储阵列的任何命令转发到辅助存储计算设备上的snap-MA。 snap-MA接收并处理由转发器媒体代理转发的针对存储阵列的命令。 来自存储阵列的响应被发送到相应的转发器媒体代理。 snap-MA有利地汇集任何数量的存储阵列命令装置，从而可以避免存储阵列处的通信信道的容量限制。 因此，与转发器媒体代理一起操作的snap-MA使得说明性系统能够将存储阵列命令的通信从客户端计算设备和/或代理媒体代理主机整合到主机的辅助存储计算设备中 snap-MA。
