The Omni Cube is a Hyper-Converged Platform. SimpliVity currently offers this infrastructure on Dell server hardware. This also includes the OmniStack Accelerator, which is a specially designed PCIe card that handles all phases of the data lifecycle. I believe they offer licensing options for additional x86 platforms.
The OmniCube appliance combines storage, compute and VMware ESXi hypervisor in one box. Each 2U OmniCube has CPU, memory, SSD, HDD and inline deduplication, compression acceleration w/multiple 10GbE interfaces. OmniCube supports a horizontal, scale-out design allowing simplified performance and capacity scaling in 2U increments. We have a Federation, or cluster, made up of 3 OmniCubes.
