The key to storage manageability is adaptation. In tradi­
tional storage systems, adaptation is performed by a hu­
man administrator, who must assess problems, and then
manually adjust various knobs and levers to bring the be­
havior of the system back to an acceptable level. Future
storage systems must themselves adapt, and in doing so,
reduce the need for manual intervention.
In this paper, we describe the Wisconsin Network Disks
project (WiND), wherein we seek to understand and de­
velop the key adaptive techniques required to build a truly
manageable network­attached storage system. WiND
gracefully and efficiently adapts to changes in the envi­
ronment, reducing the burden of administration and in­
creasing the flexibility and performance of storage for an
