Bigtable: A Distributed Storage System for Structured Data
The simple data model provided by Bigtable is described, which gives clients dynamic control over data layout and format, and the design and implementation of Bigtable are described.
File server scaling with network-attached secure disks
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
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.

This paper presents two new network-attached storage architectures, and presents a sketch of repartitionings of distributed file system functionality, including a security framework whose strongest levels use tamper-resistant processing in the disks to provide action authorization and data privacy even when the drive is in an physically insecure location.

These five RAID evolutions and the testbeds in which they are being implemented and evaluated are described.
Automatic I/O hint generation through speculative execution
The approach is to speculatively pre-execute the application’s code in order to discover and issue hints for its future read accesses, and to exploit whatever processor cycles are left idle while an application is stalled on I/O by using these cycles to dynamically analyze the application and predict its future I/Os.

Myriad, a new approach for achieving disaster tolerance in large, geographically-distributed storage systems, can achieve the same level of disaster tolerance as a typical single mirrored solution, but uses considerably fewer physical resources, by employing cross-site checksums (via erasure codes) instead of direct replication.
Energy-Driven Statistical Sampling: Detecting Software Hotspots
This work presents a dynamically adaptive hardware texture mapping system that can perform adaptive texture mapping based on a model of human visual perception which is less sensitive to the details of moving objects, which may result in significant power savings without noticeable quality degradation.
Using speculative execution to automatically hide i/o latency
A new approach to generating accurate and timely prefetches without programmer involvement is put forth, based on binary modification and requires no operating system support specific to this approach, and the viability of this approach is investigated.
