+<p>It is possible to run Trafodion on a single-node sandbox environment. Typically, any sandbox running a Hadoop distribution

+<p>For multi-node end-user clusters, your typical HBase environment should suffice for Trafodion.
+Typically, memory configuration range between 64-128 GB per node with minimum requirement of 16 GB.
+The cluster size can span from 1 to <em>n</em> nodes; a minimum of two nodes is recommended.
+A minumum of two cores is required regardless of whether you&#8217;re deploying Trafodion on a bare-metal or virtual environment.</p>
