Adaptive Data Block Placement Based on Deterministic Zones
This adaptive block placement method is based on deterministic zones, which grows dynamically (zone-by-zone) according to capacity demands. When adapting new storage subsystems, it changes only a fraction of the data layout while preserving a simple management of data due to deterministic placement.
This method uses both a mechanism focused on reducing the overhead suffered during the upgrade as well as a heterogeneous data layout for taking advantage of disks with higher capabilities.

In 1889 38% of Mexicans spoke an indigenous language, down from 60% in 1820. By the end of the 20th century, this figure had fallen to 6%. The three branches of Mayan languages are Cholan, Yucatecan and the more distantly related Huastecan or Tének. The last one also has observed a gradual decrement in the amount of speakers. The idea is the young indigenous can speak and use their mother language interacting with Internet just like Spanish or English speakers do. - So, Nenek architecture includes:
- + A social Network for indigenous languages
- + Online Services in mother lenguage such as mail, storage, contents management and web pages generators
- + Adaptive Collaborative Work for indigenous organizations.
- + Authomatic collector of linguistic/cultural digital assets.
- + Online repositories of linguistic/cultural digital assets.

AdaptStoring
- Defining Storage zones according to the application needs.- + Its own Capacity, I/O performance and Redundancy.
- + Studying the influence on the I/O performance
- + Defining an adequate block size per zone.
- + Moving a fraction of data per storage zone not per data layout.

Maximizing the performance in heterogeneous storage subsystems
Our proposal will try to discover adequate striping unit for heterogeneous adaptive storage sytems, in order to define storage zones acording to the applications features
