这个过程防止了未知个人再度初始化设备并除去所有已存储的对象(例如，密钥和证书)。
This procedure prevents unknown individuals from re-initializing the device and removing all of the stored objects (for example, keys and certificates).
这说明了EVMS遵循的一个重要原则：它只为它在系统上找到的最终(而不是临时)存储对象创建设备节点。
This demonstrates an important principle that EVMS follows: it will only create device nodes for the final (not intermediate) storage objects that it finds on your system.
但是对象存储设备是智能设备，它能作为目标和启动者，支持与其他对象存储设备的通信和合作。
But object storage devices are intelligent devices that act as both targets and initiators to support communication and collaboration with other object storage devices.
最后，放置组到对象存储设备的映射是一个伪随机映射，使用一个叫做ControlledReplicationUnderScalable Hashing (CRUSH)的算法。
Finally, the mapping of the placement group to object storage devices is a pseudo-random mapping using an algorithm called Controlled Replication Under Scalable Hashing (CRUSH).
于是，对象存储设备成为对象的平面名称空间（flat namespace），必要时，在存储系统栈中的更高层建立层次结构。
Object storage devices then become flat namespaces of objects, where hierarchy (if necessary) is built higher up in the storage system stack.
因为Ceph客户实现CRUSH，而且对磁盘上的文件映射块一无所知，下面的存储设备就能安全地管理对象到块的映射。
Because the Ceph clients implement CRUSH and do not have knowledge of the block mapping of files on the disks, the underlying storage devices can safely manage the mapping of objects to blocks.
另外，使用IBMWebSphereeXtremeScale ObjectMapAPIs的应用程序能够利用XC10设备数据缓存来存储可序列化对象。
In addition, applications using the IBM WebSphere eXtreme Scale ObjectMap APIs can utilize the XC10 appliance data cache to store serializable objects.
从存储角度来看，Ceph对象存储设备执行从对象到块的映射(在客户端的文件系统层中常常执行的任务)。
From a storage perspective, Ceph object storage devices perform the mapping of objects to blocks (a task traditionally done at the file system layer in the client).
客户文件系统向用户提供存储系统的接口，可以与元数据管理系统交互和与对象存储设备直接进行数据交换。
Client file system provides interfaces of storage system to users, can interact with metadata manage system and exchange data with OSDs.
访问OSD设备的途径，可以直接通过OSD设备驱动程序提供的API访问存储设备和通过对象文件系统进行访问。
There are two ways to acess OSD. One is through the API provided by OSD device driver, another way is through the object file system.
