For small clusters (5-50 nodes)
| Machine Type | Workload Pattern/ Cluster Type | Storage | Processor (# of Cores) | Memory (GB) | Network |
| Slaves | Balanced workload | Four to six 2 TB disks | One Quad | 24 | 1 GB Ethernet all-to-all |
| HBase cluster | Six 2 TB disks | Dual Quad | 48 | ||
| Masters | Balanced and/or HBase cluster | Four to six 2 TB disks | Dual Quad | 24 |
For medium to large clusters (100s to 1000s nodes)
| Machine Type | Workload Pattern/ Cluster Type | Storage | Processor (# of Cores) | Memory (GB) | Network |
| Slaves | Balanced workload | Four to six 1 TB disks | Dual Quad | 24 | Dual 1 GB links for all nodes in a 20 node rack and 2 x 10 GB interconÂnect links per rack going to a pair of central switches. |
