Existing storage-virtualization systems either do not support a complete set of possible storage types, do not provide flexible data-placement policies, or do not support per-file conversion (e.g., encryption). This results in suboptimal utilization of resources, inconvenience, low reliability, and poor performance. We have designed a stackable file system called redundant array of independent filesystems (RAIF). It combines the data survivability and performance benefits of traditional RAID with the flexibility of composition and ease of development of stackable file systems. RAIF can be mounted on top of directories and thus on top of any combination of network, distributed, disk-based, and memory-based file systems. Individual files can be replicated, striped, or stored with erasure-correction coding on any subset of the underlying file systems. RAIF has similar performance to RAID. In configurations with parity, RAIF's write performance is better than the performance of driver-level and even entry-level hardware RAID systems. This is because RAIF has better control over the data and parity caching.","PeriodicalId":109619,"journal":{"name":"24th IEEE Conference on Mass Storage Systems and Technologies (MSST 2007)","volume":"10 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131805457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For application-driven, periodic checkpoint operations, the state-of-the-art does not provide a solution that scales to next-generation systems. We demonstrate this by using mathematical modeling to compute a lower bound of the impact of these approaches on the performance of applications executed on three massive-scale, in-production, DOE systems and a theoretical petaflop system. We also adapt the model to investigate a proposed optimization that makes use of \"lightweight\" storage architectures and overlay networks to overcome the storage system bottleneck. Our results indicate that (1) as we approach the scale of next-generation systems, traditional checkpoint/restart approaches will increasingly impact application performance, accounting for over 50% of total application execution time; (2) although our alternative approach improves performance, it has limitations of its own; and (3) there is a critical need for new approaches to fault tolerance that allow continuous computing with minimal impact on application scalability.","PeriodicalId":109619,"journal":{"name":"24th IEEE Conference on Mass Storage Systems and Technologies (MSST 2007)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132630900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chiueh","doi":"10.1109/MSST.2007.14","DOIUrl":"https://doi.org/10.1109/MSST.2007.14","url":null,"abstract":"Mariner is an iSCSI-based storage system that is designed to provide comprehensive data protection on commodity ATA disk and gigabit Ethernet technologies while offering the same performance as those without any such protection. In particular, Mariner supports continuous data protection (CDP) that allows every disk update within a time window to be undoable, and local/remote mirroring to guard data against machine/site failures. To minimize the performance overhead associated with CDP, Mariner employs a modified track-based logging technique that unifies the long-term logging required for CDP and short-term logging for low-latency disk writes. This new logging technique strikes an optimal balance among log space utilization, disk write latency, and ease of historical data access. To reduce the performance penalty of physical data replication used in local/remote mirroring, Mariner features a modified two-phase commit protocol that in turn is built on top of a novel transparent reliable multicast (TRM) mechanism specifically designed for Ethernet-based storage area networks. Without flooding the network, TRM is able to keep the network traffic load of reliable N-way replication roughly at the same level as the no-replication case, regardless of the value of N. Empirical performance measurements on the first Mariner prototype, which is built from gigabit Ethernet and ATA disks, shows that the average end-to-end latency for a 4KByte iSCSI write is under 1.2 msec when data logging and replication are both turned on.","PeriodicalId":109619,"journal":{"name":"24th IEEE Conference on Mass Storage Systems and Technologies (MSST 2007)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131997828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fueling this growth are new federal regulations which warrant longer data retention and a general increase in the richness of data content. To cope with this growth, high performance computing and enterprise environments are making use of large disk-based solutions that consume power all the time, unlike tape-based solutions. As a consequence, the energy consumption of the storage solutions has grown significantly. In this work we propose a storage solution called GreenStor, which makes use of application hinting on top of massive arrays of idle disks (MAID) to improve energy efficiency. GreenStor is centered on MAID, but with more efficient data movement to aid in energy conservation. Specifically, we propose an extent-based metadata manager that achieves better space efficiency without sacrificing cache utilization and an opportunistic scheduling scheme that helps provide better use of application hints in a MAID system. Results show that our proposed opportunistic scheme for application hint scheduling consumes up to 40% less energy compared to traditional non-MAID storage solutions, whereas use of standard schemes for scheduling application hints on typical MAID systems is only able to achieve a smaller energy savings of about 25% versus non-MAID storage.","PeriodicalId":109619,"journal":{"name":"24th IEEE Conference on Mass Storage Systems and Technologies (MSST 2007)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133082055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
