Having two datacenters with two virtual servers at each, what is the suitable redis topology for high availability?

pk flag

I have two data centers, A and B, which has two virtual servers at each site. We have connectivity between the two sites. I'm planning to deploy one redis HA cluster with two masters and two slaves. One master, one slave on A and vice-versa at the other site.

Will it work in a disaster situation where a data center is not available? Redis recommendation is to have a 3 master server cluster. I'm confused with the concept and actually how the topology should be in this scenario. If I need more servers, how should the redis cluster be configured to handle disaster situation of loss of one site?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
