Abstract
BeeFS is a distributed file system that harnesses the free disk space of machines already deployed in the LAN. Like some special-purpose rack-aware file systems, it uses a hybrid architecture that follows a client-server approach for serving metadata and manage file replicas, and a peer-to-peer one for serving data. This characteristic allows BeeFS to aggregate the spare space of desktop disks to build a single logical volume on top of which a general purpose fully POSIX-compliant file system is implemented. BeeFS is not only more efficient than the state-of-practice that uses a dedicated server approach (eg. NFS), but also cheaper and naturally scalable.
Resumo. BeeFS é um sistema de arquivos distribuıdo que agrega o espaço ocioso dos discos de estaçoes de trabalho de uma rede local. Utiliza uma arquitetura hıbrida que mistura aspectos cliente-servidor para servir os metadados dos arquivos e as caracterısticas da arquitetura entre-pares para prover os arquivos. Esse conjunto de caracterısticas permite ao BeeFS agregar o espaço dos discos e construir um volume lógico de dados que é compatıvel com a norma POSIX. BeeFS nao é somente mais eficiente do que sistemas de arquivos que utilizam servidores dedicados (ex. NFS), mas é, também, mais escalável e barato.
