Cisco offers Unified Computing System.
Cisco's Unified Computing System (UCS) is anchored by the C240 M3 server (the 2U rackmount server pictured above). Up to 16 of these servers fit in racks together with redundant Cisco UCS 6200 Series Fabric Interconnects. A single rack offers 168 terabytes of storage in a performance configuration, 384 terabytes in a balanced configuration, or 768 terabytes in a capacity-optimized configuration. Up to 10 racks can be connected in a single UCS domain for a total of 7.68 petabytes of storage. The configuration pictured is for MapR, but Cisco also offers reference architectures for Cloudera and Hortonworks Hadoop distributions.
