The ZEO Raid storage [1] is a proxy storage that works like a RAID controller by creating a redundant array of ZEO servers. The redundancy is similar to RAID level 1 except that each ZEO server keeps a complete copy of the database.

This proposal aims to help and improve gocept.zeoraid, fixing bugs, testing and implementing needed features - for example, some included in the project's roadmap [2].
