Abstract: A system for storing data includes a rack, one or more data storage drive assemblies coupled to the rack, and a data control module coupled to the rack. The data storage drive assemblies include one or more drive mechanical modules configured to store data and one or more drive control modules coupled to the drive mechanical modules. The drive control modules control mechanical operations in the drive mechanical modules. The drive mechanical modules and the associated drive control modules are separable from one another without removing the other module from the at least one data storage drive assembly.

Abstract: In response to receiving a request from a client to store an object, a key-durable storage system may assign the object to a volume in its data store, generate a key for the object (e.g., an opaque identifier that encodes information for locating the object in the data store), store the object on one disk in the assigned volume, store the key redundantly in the assigned volume (e.g., using a replication or erasure coding technique), and may return the key to the client. To retrieve the object, the client may send a request including the key, and the system may return the object to the client. If a disk fails, the system may determine which objects were lost, and may return the corresponding keys to the appropriate clients in a notification. The system may be used to back up a more expensive object-redundant storage system.

Abstract translation: 响应于从客户端接收到存储对象的请求，密钥持久存储系统可以将对象分配给其数据存储中的卷，生成对象的密钥（例如，编码用于定位对象的信息的不透明标识符 对象在数据存储中），将对象存储在分配的卷中的一个磁盘上，将密钥冗余地存储在分配的卷中（例如，使用复制或擦除编码技术），并且可以将密钥返回给客户端。 为了检索对象，客户端可以发送包括密钥的请求，并且系统可以将对象返回给客户端。 如果磁盘发生故障，系统可能会确定丢失哪些对象，并可能会在通知中将相应的密钥返回给相应的客户端。 该系统可用于备份更昂贵的对象冗余存储系统。
