Dynamic file allocation in disk arrays

File Allocation over Disk Arrays forVideo - On -

A Video-on-Demand (VOD) server needs to store hundreds of movie titles and to support thousands of concurrent accesses. This, technically and economically, imposes a great challenge on the design of the disk storage subsystem of a VOD server. Due to diierent demands for diierent movie titles, the numbers of concurrent accesses to diierent movie titles can diier a lot. We deene access proole as ...

DADA : Dynamic Allocation of Disk Area

With current estimates of data to be managed and made available increasing at 60% per annum, disk space utilization is becoming a critical performance issue for high end users, including but not limited to IT solutions, Storage Area Networks and Virtual Machine environment. We propose Dynamic Allocation of Disk Area (DADA), a disk management framework that performs on-demand disk area allocatio...

A File Allocation Strategy for Energy-Efficient Disk Storage Systems

Exponential data growth is a reality for most enterprise and scientific data centers. Improvements in price/performance and storage densities of disks have made it both easy and affordable to maintain most of the data in large disk storage farms. The provisioning of disk storage farms however, is at the expense of high energy consumption due to the large number of spinning disks. The power for ...
