However, PCM's limited write endurance restricts its immediate use as a replacement for DRAM. Recent studies have revealed that a PCM chip which integrates millions to billions of bit cells has non-negligible variations in write endurance. Wear leveling techniques have been proposed to balance write operations to different PCM regions. To further prolong the lifetime of a PCM device after the failure of weak cell, techniques have been proposed to remap failed lines to spares and to salvage a PCM device that has a large number of failed lines or pages with graceful degradation. However, current wear-leveling and salvaging schemes have not been designed and integrated to work cooperatively to achieve the best PCM device lifetime. In particular, a non-contiguous PCM space generated from salvaging complicates wear leveling and incurs large overhead. In this paper, we propose LLS, a Line-Level mapping and Salvaging design. By allocating a dynamic portion of total space in a PCM device as backup space, and mapping failed lines to backup PCM, LLS constructs a contiguous PCM space and masks lower-level failures from the OS and applications. LLS seamlessly integrates wear leveling and salvaging and copes well with modern OSs, including ones that support multiple page sizes. Our experimental results show that LLS achieves 24% longer lifetime than a state-of-the-art technique. It has negligible hardware cost and performance overhead.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122856543","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}

We argue that route selection policies must move beyond static preferences that select routes on the basis of static attributes such as route length or which neighboring AS is advertising the route. We prove that route convergence in the presence of Byzantine misbehavior requires that the route selection metric include the dynamics of route updates as a primary component. We then describe a class of simple dynamic policies which consider the observed “ages” of routes. These gerontocratic policies can be combined with static preferences and implemented without major infrastructural changes. They guarantee convergence when adopted universally, without sacrificing most of the flexibility that autonomous systems enjoy in route selection. We empirically demonstrate that even if adopted unilaterally by a single autonomous system, gerontocratic policies yield significantly more stable routes, are more effective at avoiding prefix hijacks, and are as responsive to legitimate route changes as other policies.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122273231","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}

In this experience report, we present a dense storage case study from a large population of servers housing tens of thousands of disk drives. Previous studies have presented divergent results concerning correlation between temperature and hard disk drive failures. In our paper, we specifically establish correlation between temperatures and failures observed at different location granularities: a) inside drive locations in a server chassis, b) across server locations in a rack and c) across multiple racks in a datacenter. We also establish that temperature exhibits a stronger correlation to failures compared to the correlation of disk utilization with drive failures. Thus, we show that temperature-aware server and datacenter design plays a pivotal role in datacenter reliability. Following our case study, we present a reliability model for estimating hard disk drive failures correlated with the datacenter operating temperature. We use a physical Arrhenius model with empirically derived coefficients for our model. We show an application of the model for selecting the datacenter inlet temperature setpoint for two different server storage configurations. Finally, with the help of a datacenter cost discussion, we highlight the need to incorporate reliability-aware datacenter design for increased efficiency in large scale datacenters.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133937533","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}
