Plutus: Scalable Secure File Sharing on Untrusted Storage
TLDR
The mechanisms in Plutus to reduce the number of cryptographic keys exchanged between users by using filegroups, distinguish file read and write access, handle user revocation efficiently, and allow an untrusted server to authorize file writes are explained.
File server scaling with network-attached secure disks
TLDR
An analytic model and replay experiments suggest that NetSCSI can reduce file server load during a burst of NFS or AFS activity by about 30% and with the NASD architecture, server load can be reduced by a factor of up to five for AFS and up to ten for NFS.
A cost-effective, high-bandwidth storage architecture
TLDR
Measurements of the prototype NASD system show that these services can be cost-effectively integrated into a next generation disk drive ASK, and show scaluble bandwidth for NASD-specialized filesystems.
Active Storage for Large-Scale Data Mining and Multimedia
TLDR
An analytical model of the speedups possible for scan-intensive applications in an Active Disk system that takes advantage of processing power on individual disk drives to run application-level code is developed.
Object-based storage
TLDR
Object-based storage is described, stressing how it improves data sharing, security, and device intelligence and some industry applications and academic research using objects as a foundation for building even more intelligent storage systems are discussed.
Active Disks for Large-Scale Data Processing
TLDR
This work proposes using an active disk storage device that combines on-drive processing and memory with software downloadability to allow disks to execute application-level functions directly at the device.
A Framework for Evaluating Storage System Security
TLDR
This paper uses a trace from a time-sharing UNIX server used by a medium-sized workgroup to quantify the costs associated with each of the secure storage systems, and shows that encrypt-on-disk systems offer both increased security and improved performance over encrypt- on-wire in the traced environment.
More Than an Interface - SCSI vs. ATA
TLDR
This paper attempts to clarify the differences between SCSI disc drives and IDE (ATA) disc drives by illuminating some of these design choices and their consequences on final device characteristics to allow the community to build better storage systems with better knowledge of the trade-offs being made and the performance characteristics that result.

TLDR
The analysis shows that the majority of characteristics, including request disk arrival rate, response time, service time, WRITE performance, and request size, are environment dependent, however, characteristics such as READ/WRITE ratio and access pattern are application dependent.
Storage performance virtualization via throughput and latency control
TLDR
This paper presents a 2-level scheduling framework that can be built on top of an existing storage utility that uses a low-level feedback-driven request scheduler that is intended to meet the latency bounds determined by the SLO.
