摘要： In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.

摘要： Embodiments of the present invention are directed to a method and apparatus for receiving an input/output (I/O) request from a host computer that specifies an operation to be performed on a content addressable storage (CAS) system and determining which operation is specified by the request before receipt of the I/O request by a content addressable storage system. In another embodiment, an I/O request from a host computer is received by a first CAS which determines if the request is to be processed by another CAS system. When it is determined that the request is to be processed by another CAS system, the first CAS system may forward the request to the other CAS system. In another embodiment, an appliance receives an I/O request from a host computer to perform an operation that accesses a unit of content. The appliance may set up a communication session between the host and a CAS system so that the unit of content may be transmitted between the host and the CAS system without passing through the appliance.
摘要翻译：本发明的实施例涉及一种用于从主计算机接收指定要对内容可寻址存储（CAS）系统执行的操作并确定指定了哪个操作的输入/输出（I / O）请求的方法和装置通过内容可寻址存储系统接收到I / O请求之前的请求。在另一实施例中，来自主计算机的I / O请求由第一CAS接收，其确定该请求是否由另一CAS系统处理。当确定请求由另一个CAS系统处理时，第一个CAS系统可以将该请求转发给另一个CAS系统。在另一个实施例中，设备从主计算机接收I / O请求以执行访问内容单元的操作。设备可以在主机和CAS系统之间建立通信会话，使得可以在主机和CAS系统之间传送内容单元而不通过设备。

摘要： One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.
摘要翻译：一个实施例是用于修改存储系统中的保留周期的方法和装置，其中可以减少用于数据单元的先前定义的保留期。在另一个实施例中，可以通过更新先前定义的保留时段来响应于事件的发生来修改数据单元的保留期，直到检测到事件的发生。如果检测到事件的发生，则可以针对数据单元建立与该事件相关联的保留期。在另一个实施例中，保留类别用于定义数据单元的保留期，使得可以在不修改数据单元本身的情况下修改数据单元的保留期。在另一实施例中，对存储系统的减少保留期限的请求包括存储系统可用于验证请求的认证信息。

摘要： In one aspect, two ways of accessing a content unit stored on a CAS are provided, wherein the content unit has a content address that is computed based, at least in part, on at least a portion of its content. A first interface is provided to a file system in which the content unit is logically stored as a logical unit identified by a logical identifier, wherein the content unit is accessed in response to a request to the first interface to access the logical unit and identifying the content unit via the logical identifier. A second interface is provided through which the content unit can be accessed via the content address, wherein the content unit is accessed in response to a request to the second interface to access the content unit and identifying the content unit by the content address.

摘要： Caching techniques for use in a computer system comprising a core and at least one edge device. The core comprises at least one object addressable storage (OAS) system that stores a plurality of content units and provides an interface that enables content units to be accessed via object identifiers. The at least one edge device is configured to access at least some of the content units. At least one cache is configured to be disposed logically between the core and the at least one edge device and to temporarily store a subset of the content units. The at least one cache is further configured to have a limit on a maximum number of content units that can be stored on the at least one cache simultaneously.
