The initial number of cache nodes that the cache cluster will have. For a Memcached cluster, valid values are between 1 and 20. If you need
            to exceed this limit, please fill out the ElastiCache Limit Increase Request form at  . For Redis, only single-node cache clusters are supported at this
            time, so the value for this parameter must be 1.
