Abstract:

EH ＊ g is a high-available scalable distributed data structure. To add the availability of a system, the technique of record grouping is adopted. Every record which requires to insert must insert in a primary file and in a parity file. When a record is lost or destroyed in the primary file , the reco rd can be restored using the information of other records in the record group and the information that is saved in the parity file to win high availabil  ity.

Key words: （distributed, scalability, high availability, record-group）
