ACM存儲(chǔ)事務(wù)（TOS）是出版存儲(chǔ)研究和實(shí)踐進(jìn)展的主要期刊。存儲(chǔ)領(lǐng)域是數(shù)據(jù)可用性的基石之一。存儲(chǔ)是一個(gè)廣泛的多學(xué)科領(lǐng)域，包括網(wǎng)絡(luò)協(xié)議、資源管理、數(shù)據(jù)備份、復(fù)制、恢復(fù)、設(shè)備、安全性、數(shù)據(jù)編碼理論、密度和能效。由于企業(yè)環(huán)境和數(shù)據(jù)中心的軟硬件異構(gòu)性，設(shè)計(jì)和開發(fā)存儲(chǔ)系統(tǒng)仍然是一個(gè)挑戰(zhàn)。ACMTOS作為一本專注于存儲(chǔ)的同行評(píng)審的綜合性期刊，試圖填補(bǔ)這一空白。ACM TOS的范圍包括但不限于以下方面：存儲(chǔ)系統(tǒng)體系結(jié)構(gòu)、設(shè)計(jì)和驗(yàn)證：并行、分布式、對(duì)等和網(wǎng)格存儲(chǔ)系統(tǒng)、存儲(chǔ)區(qū)域網(wǎng)絡(luò)（SAN）、網(wǎng)絡(luò)附加存儲(chǔ)（NAS）、性能評(píng)估和監(jiān)控、預(yù)測(cè)和自適應(yīng)技術(shù)、多媒體計(jì)算應(yīng)用支持、大容量存儲(chǔ)系統(tǒng)、正式和經(jīng)驗(yàn)驗(yàn)證方法。存儲(chǔ)網(wǎng)絡(luò)：用于網(wǎng)絡(luò)存儲(chǔ)系統(tǒng)、存儲(chǔ)交換機(jī)和結(jié)構(gòu)設(shè)計(jì)的協(xié)議。存儲(chǔ)資源管理：虛擬化、管理、發(fā)現(xiàn)、存儲(chǔ)資源調(diào)配、安全性、可靠性、可擴(kuò)展性、基于策略的管理、基于對(duì)象的存儲(chǔ)設(shè)備，以及對(duì)系統(tǒng)、設(shè)備和軟件異構(gòu)性的互操作性支持。復(fù)制、備份和恢復(fù)：連續(xù)備份方法、實(shí)時(shí)和基于策略的恢復(fù)、卷、文件和應(yīng)用程序級(jí)恢復(fù)、災(zāi)難容限。操作系統(tǒng)和應(yīng)用程序支持：緩存、文件系統(tǒng)、互操作性和應(yīng)用程序編程接口的設(shè)計(jì)。信息生命周期管理（ILM）：基于可配置的策略和法規(guī)遵從性、數(shù)據(jù)存儲(chǔ)、安全和存儲(chǔ)中間件（包括數(shù)據(jù)管理系統(tǒng)）的流程和工作流來管理數(shù)據(jù)存儲(chǔ)介質(zhì)和設(shè)備：光學(xué)、磁性、聲學(xué)、基于MEMS的存儲(chǔ)設(shè)備、MRAM、生物/納米存儲(chǔ)設(shè)備、設(shè)備抽象和I/O協(xié)議。理論：高數(shù)據(jù)率、密度和低功耗的編碼算法和信號(hào)處理技術(shù)。貢獻(xiàn)可以擴(kuò)展在會(huì)議和講習(xí)班上發(fā)表的原著，也可以基于全新的未發(fā)表的作品。歡迎提供和詳細(xì)處理新興和既定主題的教程和調(diào)查文章。

ACM Transactions on Storage (TOS) is the premier journal for publishing advancements in storage research and practice. The field of storage is one of the cornerstones for data availability. Storage is a broad and multidisciplinary area that comprises of network protocols, resource management, data backup, replication, recovery, devices, security, theory of data coding, densities, and energy-efficiency. Designing and developing storage systems continues to be a challenge due to both software and hardware heterogeneity in enterprise environments and data centers. ACM TOS seeks to fill an important void as a peer-reviewed comprehensive journal focused on storage.The scope of ACM TOS includes, but is not limited to, the following areas:Storage Systems Architecture, Design, and Validation: parallel, distributed, peer-to-peer, and GRID storage systems, Storage Area Networks (SAN), Network-Attached Storage (NAS), performance evaluation and monitoring, predictive and adaptive techniques, support for multimedia computing applications, mass storage systems, formal and empirical validation methods.Storage Networking: Protocols for networked storage systems, storage switch and fabric design.Storage Resource Management: virtualization, management, discovery, provisioning of storage resources, security, reliability, scalability, policy-based management, object-based storage devices, and interoperability support for heterogeneity in systems, devices, and software.Replication, Backup, and Recovery: continuous backup methods, real-time and policy-based recovery, volume, file, and application-level recovery, disaster tolerance.Operating System and Application Support: Caching, file systems, interoperability, and design of application programming interfaces.Information Lifecycle Management (ILM): management of data based on configurable policies and regulatory compliance, processes, and workflow for data storage, security, and storage middleware including data management systemsStorage Media and Devices: optical, magnetic, acoustic, MEMS-based storage devices, MRAM, Bio/Nano-storage devices, device abstractions, and I/O protocols.Theory: Algorithms for coding, and signal-processing techniques for high data rates, densities, and low power.Contributions may extend original work published in conferences and workshops, or may be based on entirely new unpublished work. Tutorial and survey articles that provide and detailed treatment of emerging and established topics are welcome.
