Deconstructing Commodity Storage Clusters

Deconstructing Network Attached Storage systems

Network Attached Storage (NAS) has been gaining general acceptance, because it can be managed easily and files shared among many clients, which run different operating systems. The advent of Gigabit Ethernet and high speed transport protocols further facilitates the wide adoption of NAS. A distinct feature of NAS is that NAS involves both network I/O and file I/O. This paper analyzes the layere...

Visualization Clusters using Commodity Hardware

Cluster storage for commodity computation

Standards in the computer industry have made basic components and entire architectures into commodities, and commodity hardware is increasingly being used for the heavy lifting formerly reserved for specialised platforms. Now software and services are following. Modern updates to vir-tualization technology make it practical to subdivide commodity servers and manage groups of heterogeneous servi...

Storage Costs in Commodity Option

Unlike derivatives of financial contracts, commodity options exhibit distinct particularities owing to physical aspects of the underlying. An adaptation of no-arbitrage pricing to this kind of derivative turns out to be a stress test, challenging the martingale-based models with diverse technical and technological constraints, with storability and short selling restrictions, and sometimes with ...

Welfare Losses in Commodity Storage

We develop a game theoretic model of a shared commodity storage facility whose injection/ejection and space resources have been allocated to multiple selfish firms. We assume a setting where each firms injectability and deliverability depend on overall inventory within the store. This is most common in settings that involve the storage of liquids or gases such as natural gas or oil. We analyze ...
