Raja Appuswamy, David C. van Moolenbroek, Andrew S. Tanenbaum
2011 2011 IEEE 27th Symposium on Mass Storage Systems and Technologies (MSST)  
In this paper, we extend Loris to support file volume virtualization.  ...  In earlier work, we presented Loris, a reliable, modular storage stack, that solved several problems with the traditional storage stack by design.  ...  FILE VOLUME VIRTUALIZATION IN LORIS Like traditional file systems, Loris-V1 does not support virtualized file volumes.  ...

Loris - A Dependable, Modular File-Based Storage Stack

Raja Appuswamy, David C. van Moolenbroek, Andrew S. Tanenbaum
2010 2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing  
The arrangement of file systems and volume management/RAID systems, together commonly referred to as the storage stack, has remained the same for several decades, despite significant changes in hardware  ...  In this paper, we evaluate the traditional storage stack along three dimensions: reliability, heterogeneity and flexibility. We highlight several major problems with the traditional stack.  ...  File volumes in Loris will be able to provide functionalities similar to ZFS since files belonging to any volume can be allocated from any physical module. 2) Policy Assignment Flexiblity: Loris provides  ...
