Hi David, ZC sells a commercial product named "ZRS" which eliminates a ZEO storage as a single point of failure. See zope.com for more information. - C On Wed, 2003-07-16 at 15:20, David A. Riggs wrote:
From my understanding of ZEO, a single ZODB is shared between multiple Zope application clients, giving a performance boost by offloading onto the multiple app clients.
This leaves the ZODB machine as a single point of failure. We've had success in the past using DRBD to make relational databases highly available across multiple machines, I'm curious if anyone has done something similar to make the ZODB highly available in this manner, or if I'm misunderstanding a part of ZEO which handles this single point of failure.
Thanks!
