Historically, applications usually interface with persistent storage systems through protocols, abstractions and interfaces. Protocols define a series of actions that can be taken on the storage such as reading, or writing and have an implicit abstraction model such as blocks or objects. Interfaces such as general or dedicated storage networks transport protocol messages. While protocols and interfaces simplify storage system design, both impact performance by the use of abstraction models and limited operations. Emerging storage class memory has low latency and granular operations, greatly increasing the relative impact of the overhead of protocols, abstractions and interfaces. This project is re-imagining the storage interface as programmable storage, where the defined protocol involves sending encapsulated programs to the actual storage where their effect is applied. This will improve the performance of distributed systems as well as storage applications, both of which are central to Internet applications.The intellectual challenge in this project is the design of the new storage abstractions, insuring they are suitable for a variety of new storage media and that security is maintained while performance is improved. We are extending an existing storage system to include features of programmable storage while also supporting emerging consensus on low-level components used by distributed systems, such as persistent logs and transactional operations at the memory level. The project is using existing run-time code generation frameworks to insure that the programmable interface generates portable code that is also efficient. Part of the research effort is developing consensus among industry and academic researchers on the necessity and sufficiency of the storage abstractions we propose and developing educational materials to demonstrate how they should be used.

从历史上看，应用程序通常通过协议，抽象和界面与持久存储系统接口。协议定义了一系列可以在存储上采取的动作，例如阅读或写作，并具有隐式抽象模型，例如块或对象。诸如通用或专用存储网络之类的接口传输协议消息。尽管协议和接口简化了存储系统的设计，但通过使用抽象模型和有限的操作来影响性能。新兴的存储类存储器的潜伏期和颗粒状操作较低，大大增加了协议，抽象和接口的开销的相对影响。该项目将存储界面重新构想为可编程存储，其中定义的协议涉及将封装的程序发送到应用其效果的实际存储中。这将提高分布式系统的性能以及存储应用程序的性能，这两者都是Internet应用程序的核心。该项目的智力挑战是设计新存储摘要的设计，确保它们适合各种新的存储媒体，并且在提高性能的同时保持安全性。我们正在扩展一个现有的存储系统以包含可编程存储的功能，同时还支持分布式系统使用的低级组件的新兴共识，例如持续的日志和内存级别的交易操作。该项目使用现有的运行时代码生成框架来确保可编程接口生成也有效的便携式代码。研究工作的一部分是在行业和学术研究人员之间就我们提出的存储摘要的必要性和充分性建立共识，并开发教育材料以证明应如何使用它们。
