-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, we are currently investigating options for a large-scale solution where the machines (ZEO clients and ZEO server) should be separated across two data centers. Incoming traffic should be balanced between both data centers. Automatic failover and online-replication are desirable - "high-performance" is a must. The well-known options are: ZRS (ZEO) Relstorage on top of some RDBMS-related clustering/replication mechanism NEO DRDB ZEORaid Has anyone worked on such a setup or may share some experiences - especially by using one of the options above across data-centers (with a limited bandwidth inbetween and a higher latency compared to LAN).
