摘要： The techniques introduced here provide for efficient management of storage resources in a modern, dynamic data center through the use of virtual storage appliances. Virtual storage appliances perform storage operations and execute in or as a virtual machine on a hypervisor. A storage management system monitors a storage system to determine whether the storage system is satisfying a service level objective for an application. The storage management system then manages (e.g., instantiates, shuts down, or reconfigures) a virtual storage appliance on a physical server. The virtual storage appliance uses resources of the physical server to meet the storage related needs of the application that the storage system cannot provide. This automatic and dynamic management of virtual storage appliances by the storage management system allows storage systems to quickly react to changing storage needs of applications without requiring expensive excess storage capacity.

摘要： Fault isolation capabilities made available by user space can be provided for a embedded network storage system without sacrificing efficiency. By giving user space processes direct access to specific devices (e.g., network interface cards and storage adapters), processes in a user space can initiate Input/Output requests without issuing system calls (and entering kernel mode). The multiple user spaces processes can initiate requests serviced by a user space device driver by sharing a read-only address space that maps the entire physical memory one-to-one. In addition, a user space process can initiate communication with another user space process by use of transmit and receive queues similar to transmit and receiver queues used by hardware devices. And, a mechanism of ensuring that virtual addresses that work in one address space reference the same physical page in another address space is used.

摘要： A distributed object store in a network storage system uses location-independent global object identifiers (IDs) for stored data objects. The global object ID enables a data object to be seamlessly moved from one location to another without affecting clients of the storage system, i.e., “transparent migration”. The global object ID can be part of a multilevel object handle, which also can include a location ID indicating the specific location at which the data object is stored, and a policy ID identifying a set of data management policies associated with the data object. The policy ID may be associated with the data object by a client of the storage system, for example when the client creates the object, thus allowing “inline” policy management. An object location subsystem (OLS) can be used to locate an object when a client request does not contain a valid location ID for the object.
摘要翻译：网络存储系统中的分布式对象存储使用与存储的数据对象的位置无关的全局对象标识符（ID）。全局对象ID使数据对象无缝地从一个位置移动到另一个位置，而不会影响存储系统的客户端，即“透明迁移”。全局对象ID可以是多级对象句柄的一部分，其还可以包括指示存储数据对象的特定位置的位置ID，以及标识与数据对象相关联的一组数据管理策略的策略ID。策略ID可以由存储系统的客户端与数据对象相关联，例如当客户端创建对象时，从而允许“内联”策略管理。当客户机请求不包含对象的有效位置ID时，可以使用对象位置子系统（OLS）来定位对象。

摘要： Methods and system for securely capturing workloads at a live network for replaying at a test network. The disclosed system captures file system states and workloads of a live server at the live network. In one embodiment the captured data is anonymized to protect confidentiality of the data. A file system of a test server at the test network is mirrored from a captured state of the live server. An anonymized version of the captured workloads is replayed as a request to the test server. A lost or incomplete command is recreated from the states of the live server. An order of the commands during replay can be based on an order in the captured workload, or based on a causal relationship. Performance characteristics of the live network are determined based on the response to the replayed command.
