title: Do you run your Sybase environment in simplex or multiplex mode
body: <p>Evaluating a BI option for a client, wanted to check common approaches.</p>
  
  <p>If the answer is 'multiplex' then a couple of additional questions</p>
  
  <p>a) why does SAP insist this is neither a share-nothing, nor share-everything architecture, while the rule of - a node going down doesn't affect the cluster - implies you are running in the latter (share-everything). Unless every node is required to have a single failover</p>
  
  <p>b) how complicated in your experience was the administration of a multiplex</p>
  
  <p>I have run Sybase, where each instance would have a single dedicated node in multiple replication and standby configurations, but never in this "hybrid" cluster.</p>
