Subject Re: solrcloud without faceting, i.e. for failover only

: #1 is a trade off against being possibly more available to writes in the case
: of a single down node. In the cloud case, you're still open for business. In
: the classical replication case, you're no longer available for writes if the
: downed node is the master.

or to put it another way: classic replication lets you use N nodes for 
high availability reads, but you have a single point of failure for 

solr cloud gives you high availability for reads and writes -- including 
NRT support -- at the expense of more network overhead when writes happen.

it is certainly done -- specifically it is a matter of creating a 
collection with numShards=1 and replicationFactor=N.
