One important example of this phenomenon is the relationship between disk seek times and the placement and organization of file system meta-data. In this paper we show that traditional approaches to organizing meta-data in file systems are closely related to assumptions about the physical properties of disks and that for this reason traditional file systems fail to materialize the full benefits of storage virtualization. We go on to propose a different file system organization of data and meta-data designed to exploit the power of virtualized storage.<\/jats:p>","DOI":"10.1145\/1341312.1341340","type":"journal-article","created":{"date-parts":[[2008,2,8]],"date-time":"2008-02-08T15:32:16Z","timestamp":1202484736000},"page":"119-126","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Storage virtualization using a block-device file system"],"prefix":"10.1145","volume":"42","author":[{"given":"Sorin","family":"Faibish","sequence":"first","affiliation":[{"name":"EMC Corporation"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Fridella","sequence":"additional","affiliation":[{"name":"EMC Corporation"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Bixby","sequence":"additional","affiliation":[{"name":"EMC Corporation"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Uday","family":"Gupta","sequence":"additional","affiliation":[{"name":"EMC Corporation"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2008,1]]},"reference":[{"volume-title":"Proceedings of FAST '05","year":"2005","author":"Abd-El-Malek M.","key":"e_1_2_1_1_1"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/350853.350863"},{"key":"e_1_2_1_3_1","unstructured":"Ganger G. and Kaashoek M. \"Embedded Inodes and Explicit Grouping: Exploiting Disk Bandwidth for Small Files \" in Proceedings of the USENIX Winter 1997 Technical Conference January 1997.
