ZRS Version 2: Cluster servers ZRS Version 2 will provide higher performance by allowing multiple ZRS primary servers for to committing client transactions. This It eliminates the primary server as the single bottleneck for large clusters and highly dynamic sites. Cluster servers will also increase availability. If a server fails, clients automatically failover to another server. Since clients will be distributed across all servers, few clients will experience any disruption if a server fails. This architecture reduces the disruption caused by failover to a standby server in ZRS 1. as a passive secondary storage that only stores data. -----Original Message----- From: Chris Withers [mailto:[EMAIL PROTECTED] Sent: vendredi 9 décembre 2005 19:23 To: Fabrice Monaco Cc: [EMAIL PROTECTED]; zope3-dev@zope.org Subject: Re: [Zope3-dev] RE: Load Balancing Fabrice Monaco wrote: > yes, but is necassary for clustering No it isn't. A cluster of ZEO clients can run quite happilly of a storage server, and you can keep a 1hr-hot backup of the storage server with no need for ZRS. There's also DirectoryStorage and rsync. Or you could even have two totally seperate setups where content is replicated at the application level.
